NAME fsed.cpm - edit a CP/M file system.
SYNOPSIS
fsed.cpm
[-f
format]
image
DESCRIPTION
Fsed.cpm edits a CP/M file system on an image file or device.
It knows about the system, directory and data area, using sector skew on
the last two. Directory entries are decoded. The interactive usage is
self-explanatory, provided you are familiar with programming tools like
hexadecimal editors. If you are not then you should work with this program
and familiarize yourself with its usage.
OPTIONS
-
- -f
-
Use the given CP/M disk format instead of the default format.
For Apple II CP/M 80
users the disk image formats apple-do and apple-po are available. These
are DOS3.3 order and ProDOS order disk image formats respectively, and must always be specified
using the form -f apple-do or -f apple-po.
RETURN VALUE - Upon successful completion, exit code 0 is returned.
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.
ERRORS - Any errors are indicated by exit code 1.

FILES - diskdefs - CP/M disk format definitions
The diskdefs file is a plain ascii text file (in "unix" format, not Windows format)
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.
To convert between Windows text and "unix" text, two utilities (rmcr and cr) are
included in the Windows distro of the cpmtools binaries. These are included so you
can use a Windows text editor to edit a copy of diskdefs if your Windows text editor
does not edit "unix" text.
The possible locations where cpmtools first looks for the diskdefs file:
Can vary depending on the preferences of the person who builds the
cpmtools binaries (executables) from the source code.
If it's not found the current (work) directory is then searched for a
file called diskdefs.
The Windows distro uses \cpmtools\diskdefs as a default.
On a unix-like system, a ${prefix}/share/ style path
like /usr/local/share/ is a possible place that cpmtools will first
look for diskdefs.
In a Win32 system sometimes unix-like shells like cygwin
are used to build and run cpmtools instead of Windows cmd. For those installations
unix-like conventions may apply.
