Re: Passing Parms from RPGLE to RPGLE

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

This problem has nothing to do with QCMDEXC, except that submitting a 
CALL to ANYthing makes the system think it is a command-line call with 
literals. The system has no way to know what are the data types and 
lengths. If you have all digits and decimal points and all, it assumes 
it is numeric, and, specifically, that it is packed(15,5). If it has 
non-numeric stuff, or is surrounded with quotes, it assumes a character 
value and will pad out to 32 characters with blanks.

If your parameter is longer than 32 characters, because parameters to 
CALLs are passed by reference, whatever is in memory at the time is what 
the CALL'd program gets. This has nothing to do with the language - only 
the assumptions the system has made since the beginning on the 38.

The CL manual referred to in the FAQ - and the only IBM manual that 
discusses this IS a CL manual, AFAIK - gives at least 3 solutions. The 
easiest from my standpoint is to create a CMD that uses the CALL'd 
program as its CPP.

The call to QCMDEXC is not affected by this, unless you pass an 
incorrect length for the command. You can prototype it with ANY size 
character parameter (less than the max specified in the docs). Just be 
sure to send the right length, so you don't ask it to run junk.

Our customers run into this all the time, since we have path names and 
email addresses in use for our products. Lots of developers have never 
worked with parameters longer than 30 characters - address lines, all 
that - so no wonder.
