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.
Version 0.3 -- April 26, 1988 -- Carson Wilson
