RE: Help with UDS (LDA)

Alan,

I just re-read that example again... Once I named the *LDA I was able to use IN and OUT.

dcl-ds myLda dtaara(*lda);

Thx,
Greg

Hi Greg
Just quickly read this we page
Data Areas in the all free RPG @ RPGPGM.COM<https://www.rpgpgm.com/2014/11/data-areas-in-all-free-rpg.html>
And the comment at the end supports your finding

"and when the program ends that value updates the LDA."

Alan,

No. I was under the impression that OUT was not required with *auto.

So I've tried adding *usrctl to the DS.
dcl-ds *n dtaara(*auto:*usrctl);
However the program will not compile with OUT LDA or OUT *LDA in the calc specs.

I'm assuming the LDA is updated after the controlling program ends - but that's too late for me.

Greg

Hi Greg
You don't show it - but are you doing an OUT of the data area (or whatever the free form version of OUT is)?

Subject: [EXTERNAL] Help with UDS (LDA)

It's been a while since I've worked with the LDA... I'm having trouble populating the LDA from a custom program for use in an ERP program.

In my program I have the following definition:

dcl-ds *n dtaara(*auto);
dumult char(1) pos(879);
end-ds;

In the calc specs I have
dumult = '1';

My program then calls a CLLE program (has some OVRDBF, OVRPRTF, etc.), which then calls an ERP program.
The ERP pgm has the following definition:

D UDS
D DUPGM# 1 5
D DULANC 9 9
D DUM 25 224
D DIM(5) COVER PAGE MSG
D DUMF 25 224
D DUMULT 879 879
D DUSRTF 880 880

However, when I debug the process... the LDA is not updated until the initial program ends.

Any suggestions would be appreciated.
