Command Interpreter; Sample Rom Disk Image - Rockwell Automation Allen-Bradley ControlLogix 1756-MVI Programming Reference Manual

If a command interpreter is not needed, the user application may be
executed directly from the CONFIG.SYS file as shown below (where
USERAPP.EXE is the user application executable file name):
SHELL=A:\USERAPP.EXE
The user application may also be executed automatically from an
AUTOEXEC.BAT file, or manually from the console command line. In
either of these cases, a command interpreter must be loaded.
The following lines are necessary to provide resources for the OS,
application, and interrupts:
SYSTEMPOOL = 6000
STACKS = 10

Command Interpreter

A command interpreter is needed to boot the 1756-MVI to a command
prompt or to execute an AUTOEXEC.BAT file. Two command
interpreters are included in the DOS directory of the CD ROM: a
full-featured COMMAND.COM, and the smaller, more limited
TINYCMD.COM.
See the General Software Embedded DOS 6-XL Developer's Guide for
More
more information.
