You can use the COMMAND /Y command to step through a batch
program line by line, and can selectively bypass or carry out individual
commands. This functionality is useful for tracking down problems in
batch files. For more information, see COMMAND in the MS-DOS Help
on the Allegro or in Lynx on your PC.
Default AUTOEXEC.BAT File on the Allegro
The AUTOEXEC.BAT file is stored in the root directory of the C: drive.
A backup copy is also stored in the C:\UTIL directory. The file is
configured as follows:
Path = c:\;c:\util;c:\dos; a:\:
prompt $p$g
loadhigh doskey
loadfont
Changing the AUTOEXEC.BAT File
You can modify the AUTOEXEC.BAT file using a text editor. If you
need to make changes or additions, we recommend that you modify the
existing AUTOEXEC.BAT file found in the root directory on the C:
drive. Place additions at the end of the existing AUTOEXEC.BAT file.
Please note that the loadfont program must be included in the
AUTOEXEC.BAT file to enable you to use the four fonts in DOS. Do not
remove it. For more information on the AUTOEXEC.BAT file, refer to
the MS-DOS Help on the Allegro or in Lynx on your PC.

both files or bypass individual commands within the files.

To bypass all the commands in both files, follow these steps:
1) Reboot the Allegro by pressing the
(just until the screen clears). After the system starts, DOS displays the
following message:

AUTOEXEC.BAT files.
