|
|||
Some changes have been made to COPY since the manual was written. |
|||
Comparison of dates with Existence testing ON has been changed to |
|||
use the Creation date when no Modified date exists, and print |
|||
"Undated" when neither exists, yet both source and destination |
|||
disks support file date stamping. Additionally, the /X option |
|||
has been re-defined, and a new /R option has been added to |
|||
Version 1.4. Please replace Paragraph 4.1.2.9 on page 55 of your |
|||
ZSDOS manual with the following two paragraphs describing the new |
|||
options. |
|||
|
|||
|
|||
4.1.2.9.1 ERASE SOURCE FILE AFTER COPY. |
|||
|
|||
When you want to "move" a file from one area to another, the "X" |
|||
option may be used. This option causes a file or group of files |
|||
to be copied in the manner described by the default or specified |
|||
options, but after the copy and optional verify, the source file |
|||
or files are erased. You will be notified that the file has been |
|||
erased by the status "(X)" being printed on your console. To |
|||
minimize the possibility of deleting a good file when errors |
|||
exist in the copy, the Verify option should always be active, |
|||
either by default, or specified. When Verify is active, any |
|||
errors detected will disable the "X" option for that file so that |
|||
a good source file will not be deleted. The "X" option has no |
|||
configurable value, and is always assumed to be "Off" requiring |
|||
the option in the command line list to be effective. |
|||
|
|||
|
|||
4.1.2.9.2 COPY ONLY FILES WHICH EXIST (REPLACE). |
|||
|
|||
Occasionally, you may wish to update selected files to a destina- |
|||
tion in a simpler manner than naming each file, or using the |
|||
Inspect option. The "R" (Replace) option, when active, tells |
|||
COPY to transfer only files which exist on the destination direc- |
|||
tory. If the Archive option (A) is added in conjunction with the |
|||
Replace option, only files which have not been archived, AND |
|||
already exist on the destination will be archived. It should be |
|||
noted that the No Replacement (N) option is incompatible with |
|||
both the Replace and Archive options, and is disabled when either |
|||
"R" or "A" are active. |

DDTZ v2.7 |
|||
by C.B. Falconer |
|||
edited by George A. Havach |
|||
|
|||
Introduction: |
|||
============ |
|||
DDTZ v2.7 is a complete replacement for DDT, Digital Research's |
|||
famous Dynamic Debugging Tool, with improved functionality, bug |
|||
extermination, and full Z80 support. In general, DDTZ is fully |
|||
compatible with the original utility, but it has extra and |
|||
extended commands and many fewer quirks. All Z80-specific |
|||
instructions can be (dis)assembled, though in Intel rather then |
|||
Zilog format. Furthermore, DDTZ will correctly trace ('T' and 'U' |
|||
commands) both 8080 and Z80 instructions, depending on which CPU |
|||
is operating. On startup, the program announces which CPU it is |
|||
running on. |
|||
|
|||
DDTZ v2.7 now handles the 64180 added opcodes. It does NOT test |
|||
for a 64180 CPU, since this cannot be done without executing |
|||
illegal Z80 instructions, which in turn will crash some |
|||
simulators. However v2.7 does not execute any 64180 instructions |
|||
internally, only in the subject program. |
|||
|
|||
This issue supplies the "M" version assembled, to avoid errors |
|||
when switching between MSDOS and CPM systems. The command table |
|||
is updated accordingly. Most CPM users are also MSDOS users, but |
|||
not vice-versa. |
|||
|
|||
The program is invoked by typing |
|||
|
|||
ddtz<ret> |
|||
or |
|||
ddtz [d:]filespec<ret> |
|||
|
|||
In the second form, DDTZ will load the specified file into |
|||
memory starting at 0100H, unless it's a .HEX file that sets its |
|||
own load address. Besides reporting the NEXT free address and |
|||
the PC (program counter) after a successful load, DDTZ also shows |
|||
the number of memory pages needed for a SAVE. Instead of having |
|||
to write all this down, just use the 'X' command at any time to |
|||
redisplay these three values for the current application. |
|||
|
|||
NOTE: loading more code above the NEXT pointer revises these |
|||
values. |
|||
|
|||
As in DDT, when a program is loaded above the area holding the |
|||
'A' and 'U' (and now 'W') command code, these commands are |
|||
disabled, and the extra memory is released to the user. Thus, |
|||
DDTZ can occupy as little as 3K total memory space. Unlike DDT, |
|||
however, DDTZ will not overwrite itself or the system on program |
|||
loads (except .HEX files). |
|||
|
|||
At initialization, the stack pointer (SP) points to a return to |
|||
DDTZ, just like for the CCP. Thus, programs that normally return |
|||
to the CCP will be returned to DDTZ. The 'B' command |
|||
reinitializes this condition. |
|||
|
|||
|
|||
The intercept vector copies the BDOS version number, etc., so |
|||
an object program does not know that DDTZ is running (except |
|||
for BIOS-BDOS vector size). Thus, programs that check the version |
|||
number should execute correctly under DDTZ. |
|||
|
|||
All input parameters can now be entered in any of three formats: |
|||
|
|||
(1) hexadecimal (as in DDT), |
|||
(2) decimal, by adding a leading '#' character, |
|||
(3) ASCII, by enclosing between either single or double |
|||
quotes; either one or two characters are allowed. |
|||
|
|||
Leading blanks in command lines and parameters are absorbed. |
|||
Either a comma or a (single) space is a valid delimiter. |
|||
Either uppercase or lowercase input is accepted. |
|||
|
|||
The default command (for anything not otherwise recognizable) |
|||
is 'H'. This allows convenient calculation, along with the other |
|||
features described below. So, to convert a number, just enter |
|||
it! |
|||
|
|||
As in DDT, the prompt character is '-', and the only error |
|||
message is the query ('?'), which generally kicks you back to |
|||
command mode. |
|||
|
|||
New Commands (Over DDT): |
|||
======================= |
|||
|
|||
NOTE: letters in parenthesis, e.g. "(U)", show the equivalent |
|||
command for DDTZM version (compatible with MSDOS debug). |
|||
|
|||
@ Sets or shows (with no parameter) the internally stored |
|||
"base" value. Also used with the 'S' and 'D' commands as |
|||
an optional parameter (though without the '@') to display |
|||
memory from an arbitrary base marker (offset). When set to |
|||
zero (the default), it does not affect any screen displays. |
|||
|
|||
B B)egin: resets the USER stack pointer to its initial value, |
|||
such that any program that exits by an RET will return to |
|||
DDTZ. DDTZ provides a default stack space of |
|||
approximately 24 bytes for user programs. |
|||
|
|||
C C)ompare first_address,last_address,against_address: shows |
|||
all the byte differences between two memory areas, in the |
|||
format |
|||
|
|||
XXXX aa YYYY bb |
|||
|
|||
where XXXX and YYYY are the comparative memory addresses, |
|||
and aa and bb are the corresponding byte values. Can be |
|||
used to verify the identity of two files by first |
|||
loading them into different memory areas with the 'R' |
|||
command (see below). |
|||
|
|||
|
|||
W Write: stores the modified memory area to disk under the |
|||
(K) filename specified by the 'I' command, overwriting the |
|||
original file from which it was loaded (the user is queried |
|||
before doing so). By default, the image of memory from |
|||
0100H through the "NEXT" value -1 is saved. "K first_addr, |
|||
last_address" overrides this and allows writing ANY memory |
|||
area to a file. Almost a necessity for CPM 3.0 (no SAVE!). |
|||
K)eep on DDTZ |
|||
|
|||
X eXamine: redisplays the "NEXT PC SAVE" report at any time. |
|||
(Q) Q)uery size on DDTZ. |
|||
|
|||
S S)earch first_address, last_addr, value: searches the |
|||
(W) specified memory area for the value (a 16-bit word, not a |
|||
byte) and shows the locations of all such. Very useful for |
|||
finding CALL's or JMP's to a particular address, etc. |
|||
W)here on DDTZ |
|||
|
|||
Y Y)our_option parm1,parm2,address: executes an arbitrary |
|||
routine at the specified address, with the BC and DE |
|||
registers set to parm1 and parm2, respectively. |
|||
|
|||
Z Displays (but does not alter) the Z80's alternate register |
|||
set, including the index registers (disabled if running on |
|||
an 8080). On Z80's, automatically included as the last |
|||
part of the display by the 'X' command. |
|||
|
|||
|
|||
Based (Offset) Displays: |
|||
======================= |
|||
|
|||
The 'D' and 'E' commands can use a stored base value (offset), |
|||
as set by the '@' command. The current @ value may be |
|||
overridden for a single execution of these commands by adding the |
|||
base as an extra parameter in the command line. The effect is |
|||
to add this value to the first/last address and display |
|||
accordingly. The address listing on the left becomes XXXX:YYYY, |
|||
where XXXX is the offset address and YYYY is the actual memory |
|||
address being displayed. For example, if you have a data area |
|||
located at 42B7H and wish to preserve easy access, just enter |
|||
"@42b7". Now, "d0,3f" will dump memory starting at 4237H. |
|||
|
|||
|
|||
Further Changes from DDT: |
|||
======================== |
|||
|
|||
A A)ssemble now accepts the full Z80 as well as 8080 |
|||
instruction set, although it expects them in Intel rather |
|||
than Zilog format (see notes below under the 'L' |
|||
command). When in doubt, see the mnemnonic list below. |
|||
|
|||
D D)isplay or D)ump will accept an optional third parameter |
|||
to set the base value for a single execution only. Format |
|||
has been cleaned up. |
|||
|
|||
H H)ex_arithmetic on two values also shows their |
|||
difference in decimal. With only one value, converts to |
|||
hexadecimal, decimal, and ASCII (low-order byte only). |
|||
|
|||
|
|||
N N)ame now allows drive specification (d:...) and sets up |
|||
(I) the complete command line, including both FCB's (at |
|||
addresses 005CH and 006CH). The tail (stored at 0081H up) |
|||
is NOT upshifted. |
|||
I)nput on DDTZ |
|||
|
|||
U U)nassemble now displays the raw hexcode, especially handy |
|||
(L) when examining non-code areas. Intel (8080 style) mnemonics |
|||
are used, so some disassembled instructions may look |
|||
strange. E.g., the Z80's 'IN B,(C)' and 'OUT (C),B' become |
|||
'INP B' and 'OUTP B', respectively; 'LD (nnnn),BC' becomes |
|||
'SBCD nnnn', 'ADD IX, BC' becomes 'DADX B', and 'JP (IX)' |
|||
becomes 'PCIX'. |
|||
L)ist on DDTZ |
|||
|
|||
L L)oad now permits loading a file into memory with an |
|||
(R) offset, which is added to the default load address of |
|||
0100H. When reading in a .HEX file with a preset bias, |
|||
the 'R' command will not transfer control to an invalid |
|||
execution point. Another execution of the 'R' command will |
|||
reread the input file, e.g.: |
|||
|
|||
n blah<ret> |
|||
l<ret> |
|||
...modify the code and generally mess about... |
|||
l<ret> |
|||
|
|||
The original file is reloaded, and the modifications are |
|||
removed. |
|||
R)ead on DDTZ |
|||
|
|||
E E)nter, like D)isplay, now accepts an optional second |
|||
(S) parameter to set the base value for a single execution |
|||
only. |
|||
S)ubstitute or S)et on DDTZ |
|||
|
|||
T T)rap/trace on termination now shows the complete CPU |
|||
state. Traps and traces no longer lock up when a user RST |
|||
7 instruction is executed. Tracing of BDOS/BIOS calls is |
|||
heavily trun cated, avoiding clutter and preventing system |
|||
crashes. |
|||
|
|||
NOTE: Most of the UNDOCUMENTED Z80 op-codes are handled. Others |
|||
can crash the system. |
|||
|
|||
R R)egisters also shows what two-byte values the HL and SP |
|||
(X) registers are actually pointing to. On Z80's, displays the |
|||
alternate register set. |
|||
eX)amine on DDTZ |
|||
|
|||
NOTE: Any use of the 'W' or 'L' command resets the system DMA |
|||
transfer address to the standard default value of 0080H. |

FILEATTR |
|||
Version 1.6 |
|||
|
|||
Gene Pizzetta |
|||
January 18, 1992 |
|||
A ZSDOS utility, copyright (c) 1988 by Carson Wilson. |
|||
|
|||
|
|||
FILEATTR (FA) is a utility that allows rapid settin, resetting, |
|||
or displaying of file attributes under ZSDOS, ZRDOS, and CP/M |
|||
2.2. Several additional features are available under ZCPR3, |
|||
including error flag setting, error handler invocation, an |
|||
enhanced display, and better error detection. |
|||
|
|||
FA will not run under CP/M 3.0 or Z3PLUS. |
|||
|
|||
USAGE: |
|||
|
|||
FILEATTR {dir:}{afn} {{/}options} |
|||
|
|||
If a DIR or DU specification is not given, the current directory |
|||
is assumed (under vanilla CP/M only the drive is significant). |
|||
If no ambiguous or unambiguous filename is given, all files |
|||
("*.*") are matched. |
|||
|
|||
If no attribute options are given, FILEATTR merely displays the |
|||
current state of each file's attributes. Files are displayed in |
|||
the order that they appear in the directory. |
|||
|
|||
Once operation begins, FA cannot be aborted by the user. If a ^C |
|||
is entered at the keyboard, all screen output stops, but file |
|||
attribute operations continue to completion. If that was not the |
|||
case, attributes might be set on some entries for a file and not |
|||
on others. Nevertheless, suppressing screen output speeds things |
|||
up a bit. |
|||
|
|||
OPTIONS: A leading slash is required unless the option list is |
|||
the second parameter on the command line. Options may be |
|||
separated by spaces, commas, or nothing at all. |
|||
|
|||
ATTRIBUTE OPTIONS: These options set (turn on) corresponding |
|||
attributes on files matching the file specification. Attributes |
|||
not specified by an attribute option remain unchanged. |
|||
|
|||
If the option is preceded by a minus ("-") or by an "N", the |
|||
corresponding attribute is reset (turned off). |
|||
|
|||
1 F1. This is a user attribute which has no predefined |
|||
meaning. |
|||
|
|||
P Public (f2). Under ZSDOS, when this attribute is set, |
|||
a file is available from any user area of the disk on |
|||
which it resides. A file cannot be made public if |
|||
another file with the same name exists in any other |
|||
user area on that drive. In that case FA will issue an |
|||
error message and leave the attribute off. |
|||
|
|||
D Inhibit access datestamp (f3). Under ZSDOS, when this |
|||
attribute is set, the file's access datestamp will not |
|||
be updated, which may speed file access slightly. If |
|||
the attribute is turned off, normal access datestamping |
|||
resumes. |
|||
|
|||
4 F4. This is a user attribute which has no predefined |
|||
meaning. |
|||
|
|||
W Wheel protect (f8). Under ZSDOS, when this attribute |
|||
is set, the file becomes read-only when the wheel byte |
|||
is off and cannot be erased. If the wheel byte is on, |
|||
the file can be erased normally. |
|||
|
|||
R Read only (t1). When this attribute is set, the file |
|||
cannot be erased or modified by most programs. |
|||
|
|||
S System (t2). When this attribute is set, the file |
|||
becomes a "hidden" file that will not be found by most |
|||
directory programs or by most well-behaved utilities |
|||
that accept ambiguous filenames. (FA must find system |
|||
files, of course.) |
|||
|
|||
A Archive (t3). When this attribute is set, it signals |
|||
some archival programs that the file has not been |
|||
modified since it was last backed up. If a file is |
|||
modified, ZSDOS and ZRDOS turn this attribute off. |
|||
CP/M does not fully support this attribute, however. |
|||
|
|||
OTHER OPTIONS: These options affect only the screen display. |
|||
|
|||
Q Quiet mode. Console output is suppressed unless there |
|||
is an error. All other operations are performed |
|||
normally. |
|||
|
|||
X Screen paging off. With this option, screen paging is |
|||
turned off. The screen can still be paused by pressing |
|||
any key except ^C. |
|||
|
|||
ERRORS: Under ZCPR3, errors will cause FA to set the program |
|||
error flag and to invoke the error handler. The error flag will |
|||
be set to the following values: |
|||
2 invalid directory specification |
|||
4 miscellaneous (conflicting file, no files on disk) |
|||
10 no matching files found (no error handler) |
|||
18 Disk read-only |
|||
19 Invalid option |
|||
|
|||
For error code 10 (no matching files found), the error flag is |
|||
set, but the error handler is not called. |
|||
|
|||
In addition, under ZCPR 3.3 and above, an invalid directory |
|||
specification will abort FA to the error handler, but no message |
|||
is printed. |
|||
|
|||
The following error messages may be seen: |
|||
|
|||
Conflicting entry, can't set public attribute |
|||
If there are files with the same name in other user areas of |
|||
the disk, the public attribute cannot be set. |
|||
|
|||
No files on disk |
|||
The disk directory is empty. |
|||
|
|||
Bad Option: /o |
|||
The command line option shown is unknown to FILEATTR. |
|||
|
|||
Drive R/O |
|||
The drive is set to read-only by the operating system and |
|||
attributes cannot be changed. |
|||
|
|||
CP/M version 2.x required |
|||
FILEATTR will not run on this system. |
|||
|
|||
BIOS write error near directory sector n |
|||
An error occurred at or near the given directory sector, |
|||
which is expressed as a decimal offset from the beginning of |
|||
the directory. |
|||
|
|||
BIOS set track detected - FA aborting |
|||
A background program is attempting to modify the current |
|||
track setting. The background program must be removeed |
|||
before running FA again. |
|||
|
|||
Not Wheel |
|||
Under ZCPR3 the wheel byte must be set before FILEATTR can |
|||
be run. |
|||
|
|||
CONFIGURATION: While no installation is necessary, all options |
|||
can be set as defaults, if you prefer, using ZCNFG. The |
|||
configuration options are fully explained on the ZCNFG help |
|||
screens. |
|||
|
|||
It is best not to change the name of the configuration file. Its |
|||
special name assures that ZCNFG will always find the correct CFG |
|||
file, even if the name of FA has been changed or if more than one |
|||
version of FA is online. |
|||
|
|||
HISTORY: |
|||
|
|||
Version 1.6 -- April 14, 1991 -- Gene Pizzetta |
|||
Now displays target DU and directory name in summary. Fixed |
|||
bug that caused "GO" to be displayed as program name, if it |
|||
was re-invoked with the GO command. |
|||
|
|||
Version 1.5 -- March 27, 1991 -- Gene Pizzetta |
|||
Now calls CP/M version checking routine (it was there, but |
|||
it wasn't called). Changed error codes: 10, no matching |
|||
files found. "No files on disk" error now gets |
|||
miscellaneous error code (4). Error 10 does not invoke |
|||
error handler. Not released. |
|||
|
|||
Version 1.4 -- March 20, 1991 -- Gene Pizzetta, Howard Goldstein |
|||
Code to check module data byte (S2) was replaced by Howard |
|||
Goldstein's elegant solution which uses a "true" extent |
|||
number: ((data_mod * 32) + extent). Entering a ^C no |
|||
longer really aborts FILEATTR; instead FA immediately prints |
|||
"Wait..." on the screen, turns off paging, turns on quiet |
|||
mode, sets the results flag, and finishes what it was doing. |
|||
All this is to prevent unexpected results when only some of |
|||
a file's directory entries are changed. All errors |
|||
including a conflicting file found during a PUBLIC request, |
|||
now set the program error flag and invoke the error handler |
|||
so an active SUBMIT or ZEX script can be aborted. The error |
|||
flag will have the following values: 2, invalid directory; |
|||
10, no files on disk; 18, disk is read-only; 19, invalid |
|||
option; 4, all other errors. If no matching files are |
|||
found, the program error flag will be set to FFh, but the |
|||
error handler will not be invoked. A few other code changes |
|||
were made, including a check for CP/M-Plus, under which |
|||
FILEATTR will not work. Not released. |
|||
|
|||
Version 1.3 -- February 22, 1991 -- Gene Pizzetta |
|||
Corrected bug that caused faulty operation on large files: |
|||
The module data byte (S2) byte was not being checked, so |
|||
such files appeared 2 or more times in the directory display |
|||
and the public routine was often not finding conflicting |
|||
files. Added configuration byte and command line option (X) |
|||
for screen paging (paging is suppressed in quiet mode). |
|||
Made quiet mode responsive to ZCPR quiet flag and changed Q |
|||
command line option to toggle. Usage screen reflects |
|||
current effect of X and Q toggles. Attribute configuration |
|||
area changed to be compatible with ZCNFG TOGL3 routine. |
|||
Actions of D and ND options reversed so they work the same |
|||
as the others. Added configuration byte for printing |
|||
summary line even in quiet mode, as suggested by Howard |
|||
Goldstein. Removed blank lines from screen display, |
|||
allowing three more filenames to be shown. Removed tabs |
|||
from usage screen so PRINT and PSTR are not needed. |
|||
Eliminated leading zero from user number display. Now |
|||
prints "file" instead of "files" in summary when only 1 |
|||
matching file is found. Ditto for attribute(s) altered. |
|||
|
|||
Version 1.2 -- November 30, 1988 -- Carson Wilson |
|||
Fixed bug of no program name display when FILEATTR's name |
|||
was 8 characters long. |
|||
|
|||
Version 1.1 -- October 30, 1988 -- Carson Wilson |
|||
Now wildcards the command forms "FA d: /options" and "FA d: |
|||
options." |
|||
|
|||
Version 1.0 -- September 26, 1988 -- Carson Wilson |
|||
If a filespec is given, no leading slash is required before |
|||
the options. Link with version 4 libraries. Removed /X |
|||
option--ZSDOS 10T always closes the first extent when a file |
|||
is written to. Changed summary to read "files matched". |
|||
|
|||
Version 0.9 -- July 7, 1988 -- Carson Wilson |
|||
Increased length of search FCB (AMBFIL) by one byte. Set up |
|||
AMBFIL as '?' + 35 binary 0's. ZRDOS and CP/M zero the |
|||
drive byte (FCB+0) during search next calls, so reinitialize |
|||
it to '?' before rescanning the directory. PROGID now |
|||
prints stored name on GO/JUMP. |
|||
|
|||
Version 0.8 -- June 26, 1988 -- Carson Wilson |
|||
Use SYSLIB PRINT for help display. VPRINT does not expand |
|||
tabs. Now traps disk track changes at the BIOS level. |
|||
Allows '-' as well as 'N' for "negate option." Auto- |
|||
wildcards FCB1 for attribute set as well as display. |
|||
|
|||
Version 0.7 -- May 24, 1988 -- Carson Wilson |
|||
Cosmetic changes to help, display. Made public routines |
|||
faster by 1/2 directory scan average. Consolidated file |
|||
attribute setting/resetting routines for efficiency and |
|||
clarity. |
|||
|
|||
Version 0.6 -- May 14, 1988 -- Carson Wilson |
|||
Changed "Publ" to "Publc" and "Priv" to "Privt". Added Q |
|||
and X options, made options installable. Added test for bad |
|||
ZCPR directory & chain to error handler. |
|||
|
|||
Version 0.5 -- May 4, 1988 -- Carson Wilson |
|||
Fixed bug at CHKRO inherited from MAKE.ASM. Uses Bridger |
|||
Mitchell's FRESET to reset disks. Uses ZCPR invocation name |
|||
in signon, help, etc. Added F4 attribute. Now includes all |
|||
valid ZSDOS attributes. Help now fully "smart" under ZCPR. |
|||
Reworked VID3.Z80 and VID4.Z80 from VLIB11 and moved them |
|||
into FA.Z80 (see end of file). Put STNDOUT mode ON by |
|||
default at beginning of each attribute display sequence for |
|||
faster ZCPR displays. |
|||
|
|||
Version 0.4 -- April 27, 1988 -- Carson Wilson |
|||
Tests for matching files at other user areas before setting |
|||
the public attribit. |
|||
|
|||

Option Q -- If the ZCPR quiet flag is set, FILEATTR will always default to |
|||
quiet mode. To make quiet mode the default at all times, even when running |
|||
under CP/M, set this configuration option to "Yes". Whatever is selected |
|||
here can be toggled with the command line "Q" option. |
|||
|
|||
Option X -- A "Yes" will cause FILEATTR to page screen output by default. |
|||
A "No" will default to continuous scrolling. The chosen default can be |
|||
toggled with the command line "X" option. Screen paging is always turned |
|||
off in quiet mode. |
|||
|
|||
Option R -- As distributed, FILEATTR prints nothing to the screen when it |
|||
is operating in quiet mode. If this configuration option is "Yes", the |
|||
results summary line that gives the number of matching files found and the |
|||
number of attributes changed will be printed even in quiet mode. |
|||
|
|||
Option S -- Enter the number of lines on your video display screen. Under |
|||
ZCPR 3.3 and higher, the number of screen lines for paging is obtained from |
|||
the environment descriptor. This configuration parameter is used only if |
|||
running under CP/M. |
|||
|
|||
|
|||
Attribute Configuration Options |
|||
|
|||
As distributed, FILEATTR will not change any file attribute unless |
|||
explicitly commanded to do so by a command line option. To configure |
|||
FILEATTR to turn a file attribute ON or OFF by default, toggle the |
|||
appropriate configuration selection. |
|||
|
|||
For example, to make FILEATTR set all matching files to Public by default, |
|||
change the "Public attribute" setting to "Turn On". Then FILEATTR will set |
|||
the specified files to Public unless the /NP command line option is given |
|||
(which would cause the files to be set to Private). Since there is no |
