RE: SYSTEM()

[Scott Mildenberger <Smildenber@xxxxxxxxxxxx>]

It is actually a C function so it should be documented in the C reference (I
used a book that actually predates the AS/400).  Here is how to prototype
it:

d system          pr            10i 0 extproc('system')        
d   cmd                           *   value options(*string)   
                                                               
You will also want to import 

d error           s              7    import('_EXCP_MSGID')  

If system returns a value less than zero then the message id causing the
problem will be contained in 'error'.  You will have to reference binding
directory QC2LE in order for the binder to find the function.

We prefer 'system' over QCMDEXEC because of the better error handling.  We
have embedded the function into a procedure in a service program that
implements a MONMSG type of capability.  In a lot of cases we have taken to
using 'system' inside our RPG programs to eliminate the front end CL's that
were sometimes necessary in the past.  Let me know if you have any other
questions.
