Use the given CP/M disk <I>format</I> instead of the default format.
|
|
<BR><BR>
|
|
|
|
|
|
<DT><b>mode</b> Octal file mode, as used in the <b>unix command chmod</b>.<DD>
|
|
|
|
<BR>
|
|
<b>Numeric (Octal) file mode:</b>
|
|
<br>
|
|
<br>
|
|
From one to four octal digits. Any omitted digits are assumed to be leading zeros.
|
|
<br>
|
|
<br>
|
|
<b>chmod Examples:</b>
|
|
<br>
|
|
<br>
|
|
chmod 400 file - Read by owner<br>
|
|
chmod 040 file - Read by group<br>
|
|
chmod 004 file - Read by world
|
|
<br>
|
|
<br>
|
|
chmod 200 file - Write by owner<br>
|
|
chmod 020 file - Write by group<br>
|
|
chmod 002 file - Write by world
|
|
<br>
|
|
<br>
|
|
chmod 100 file - execute by owner<br>
|
|
chmod 010 file - execute by group<br>
|
|
chmod 001 file - execute by world
|
|
<br>
|
|
<br>
|
|
To combine these, just add the numbers together:
|
|
<br>
|
|
<br>
|
|
chmod 444 file - Allow read permission to owner and group and world<br>
|
|
chmod 777 file - Allow everyone to read, write, and execute file

cpmchmod -f apple-do exmplcpm.dsk 444 bhead.c

This will likely only be of interest to programmers. In a Win32 system the

exit code can be trapped in a batch file as an "ERRORLEVEL" or as a
|

return value when run from another Win32 console program written in a
|
|
language like C.

|
<B>FILES - diskdefs - CP/M disk format definitions</B><BR><BR>
|
|
|
|
The diskdefs file is a plain ascii text file that serves as a database of
|
|
disk and disk image format definitions. It can be reviewed for available CP/M
|
|
formats and their names. For Apple II CP/M 80 users the disk
|
|
image formats apple-do and apple-po are available.
|
|
<BR><BR>
|
|
<b>The possible locations where cpmtools first looks for the diskdefs file:</b>
|
|
<BR>
|
|
<BR>
|
|
- Can vary depending on the preferences of the person who builds the
|
|
cpmtools binaries (executables) from the source code.
|
|
<BR><BR>
|
|
- The location is also installation dependent and the diskdefs file
|
|
may also have been renamed.
|
|
<BR>
|
|
<BR>
|
|
<b>If it's not found the current (work) directory is then searched for a
|
|
file called diskdefs.</b>
|
|
<BR>
|
|
<BR>
|
|
<b>On a unix-like system</b>, a <b>${prefix}/share/</b> style path
|
|
like <b>/usr/local/share/</b> is a possible place that cpmtools will first
|
|
look for diskdefs.
|
|
<BR>
|
|
<BR>
|
|
<b>In a Win32 system</b> sometimes unix-like shells like cygwin
|
|
are used to run cpmtools instead of Windows cmd. For those installations
|
|
unix-like conventions probably apply.
|
|
<br>
|
|
<br>
|
|
For cpmtools installations targetted at the average
|
|
Windows user who does not have a unix-like shell and uses the Windows cmd
|
|
prompt to run cpmtools there is no standard shared place that cpmtools will first
|
|
look for diskdefs. Pathed File names like <b>\cpm\diskdefs</b> or
|
|
even <b>c:\cpmtools\diskdefs</b> are possible.
