I have a program that is doing this on V5R4 as follows:

fdspfile cf E workstn

d screenDS e ds
extname(dspfile:screenc:*input)



The exfmt to screenc loads the data structure. It is very
similar to the use of a DS on a file. Reading the file loads the DS.

fpffile uf E K DISK

d mstrDS e ds extname(pffile)

Hi, all.

I just added a DS to a procedure with the idea that it would be
populated automatically when the user enters data. In the record
MyFormat is one zoned decimal field, all the rest are

character fields.

At the EXFMT MyDSPF, I get MCH1202.

The code is basically this :
D MyDS E DS EXTNAME ( MyDSPF :

MyFormat:*INPUT )

/FREE
MyNumField = 0;
EXFMT MyFormat;

While debugging, there seems to be confusion between MyNumField of
MyDS and MyNumField of MyDSPF. If I do EVAL MyNumField at

the EXFMT, I

see that MyNumFld = 0. If I step into the EXFMT, and then type EVAL
MyNumField, I then see that MyNumFld = blank. I've tried INZ on the
MyDS declaration and also CLEAR MyDS.

What am I doing wrong? Is there a better way?

In the DSPF there are many many field names that occur in different
record formats.
For that reason, I wanted to store the contents of MyFormat in a
global qualified DS.



Thanks
