RE: Data Areas in RPG and QCMDEXC

I would suggest using a User Space instead, but there is an OS/400 API
retrieve a data area's content: QWCRDTAA
Changing it requires that you call QCMDEXC again with CHGDTAARA specified.
If you have the RPG ToolKit you could just use a user space, and the
CrtUserSpace, ChgUsrSpace, and RtvUsrSpace procedures to create, change, and
retrieve the data of a user space. If you don't have the ToolKit, the
QWCRDTAA is your best choice for data areas, otherwise look into the user
space APIs.

Subject: Data Areas in RPG and QCMDEXC

I run a CRTDTAARA command with QCMDEXC. I'm able to create the data area
with no problems. The thing I'm not sure about is will I be able to
access the data area from other RPG programs. How can I access a data
area in RPG if I don't define the data area first? The data area is
temporary and the name is a concatenation of the user name and job
number. If I need to I can simply use a CL program and I think I will be
ok, but I was just curious if it is possible in RPG.
