<title>System Command Descriptions</title>
<para>
This section contains descriptions for each of the command
programs that are supplied with NitrOS-9. These programs are usually
called using the shell, but can be called from most other NitrOS-9
family programs such as BASIC09, Interactive Debugger, Macro Text
Editor, etc. Unless otherwise noted, these programs are designed to
run as individual processes.
</para>
<warning>
<para>
Although many NitrOS-9 commands may work on Level 1 or Level
2 systems, there are differences. Take care not to mix command
files from Level 1 systems on Level 2, 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.
