RE: Parameter passing from CLP to COBOL/400 program

Dan, Kathir,

I am not an RPG person but from what I remember, zoned is the same as zoned
decimal in COBOL or in other words Display numeric so in COBOL FLD PIC 9(5)
Value 12345 is F1F2F3F4F5 so simply passing the value to a PIC 9(n) field
will work. The CL should define the value as *CHAR.

I am certain there are better ways to accomplish your goal than I am
going to suggest you try, but in case you need a solution now and
better responses are slow in coming...

Idea #1:
Call the Cobol program with the parameter specified in hexadecimal. 
For example, if you wanted to use 123456 as the parameter value, you
would use this:
       CALL   COBOLPGM  PARM( X'F1F2F3F4F5F6' )
Of course, if you are dealing with a variable, you might have to build
the above command string and invoke it via QCMDEXC.  I.e.:
       CHGVAR  &CMD VALUE('CALL   COBOLPGM  PARM( X''' *CAT
                   &HEXZONED *CAT ''' )' )
       CALL    QCMDEXC  PARM( &CMD  100 )
You would have to figure a way to build the value for &HEXZONED.  BTW,
I'm not really sure the hex idea would work.  Before you go coding to
build the value for &HEXZONED, I would suggest you try a hard-coded
call (the example call with the PARM( X'F1F2F3F4F5F6' ))

Idea #2:
If you have the RPG compiler, create an RPG program that takes the CL
packed variable as an *Entry parameter, move that variable to a data
structure subfield defined as zoned.  (Question:  Can you use a DS
subfield as a parameter to call another program?)  Non-ILE RPG may be
the best to try as I think ILE-RPG defaults zoned definitions to packed
internally.  Maybe you can do a similar trick in Cobol?

HTH, Dan
