<title>System Command Descriptions</title>
<para>
This section contains descriptions for each of the command
programs that are supplied with OS-9. These programs are usually
called using the shell, but can be called from most other OS-9
family programs such as BASIC09, Interactive Debugger, Macro Text
Editor, etc. Unless otherwise noted, these programs are designed to
run as individual processes.

<emphasis>WARNING</emphasis>
- ALTHOUGH MANY OS-9 COMMANDS MAY WORK ON LEVEL ONE OR LEVEL
TWO SYSTEMS, THERE ARE DIFFERENCES. TAKE CARE NOT TO MIX COMMAND
FILES FROM LEVEL ONE SYSTEMS ON LEVEL TWO, OR THE REVERSE.

<para>
NOTE: The syntax of the commands given does not include the shell's
built in options such as alternate memory size, I/O redirection,
etc. This is because the shell will filter its options out of the
command line before it is passed to the program being called.
