RE: Passing unwanted parameters -- RPG400-L

It is using the LDA if you don't specify a name and don't use DTAARA keyword.
Without DTAARA keyword and UDS it is looking for the name to match.

If you don't specify the Dtaara it's using the LDA, right? So what you
were wanting to do with UDS w/o specifying the Data Area, you could do
with Dtaara(*LDA) instead, which would allow you to do the INs and OUTs.

Scott,

Actually, I discovered that if you define the data area with the
following
definition in both caller *and* the called program, then it can be both
read
*and* written in the called program:

D ExtraParm UDS 32 Dtaara(EXTRAPARM)

However, if you define it without the DTAARA keyword in the called
program,
then it gets read in automatically, but you can't use the OUT opcode on
it,
since the program thinks it's not a data area.

For some reason, I thought that the IN and OUT opcodes worked on UDS's
which
didn't specify the DTAARA keyword, but apparently not.
