Introduction to MPE XL for MPE V Programmers Migration Guide

COMMAND intrinsic (CM) 
(changed) 

You use the COMMAND intrinsic in CM to execute a command from an
application.  If an MPE V/E command is passed that MPE XL does not
support, MPE XL returns an error message (CIERROR 9013) stating that the
command is not supported.  COMMAND allows process creation commands, such
as RUN or FCOPY, if the caller has PH capability, or if the program being
run was prepared or linked with PH capability.

The parmnum parameter has the following significance:

 *  If it returns a positive value, that number is the file system error
    number which prevented the command from executing.

 *  If it returns a negative value, that number (as a positive value) is
    the column number where the error occurred.
