Re: PTF enhancements for RPG -- RPG400-L

I had problems with the PDSD as well. Perhaps you could report that issue to IBM - as far as they are concerned both features were in the same runtime PTF.

As to the definitions - did you add the dcl-f? If you have that as a template that should cure the errors. Otherwise I guess you have to use the qualified names on the Like clause.

Thanks Jon,

I've just learned that we are on TR5, with some PTF's recently applied.

SAMEPOS works for simple data structures, but the PSDS enhancements for the Job number and System name don't.

I'm guessing that not enough PTFs were applied.

BTW - I tried copy/paste your suggestion into my program. I get:

RNF7030: The name or indicator HDIAG1 is not defined.
RNF3523: External description SET_DIAG for data structure is not found; data structure is ignored.
RNF0202: THE PARAMETER FOR SAMEPOS MUST BE A SUBFIELD PREVIOUSLY SPECIFIED IN THIS DS.

I am able to eliminate the RNF7030 and RNF0202 if I insert a line:
"diag1_set like(hdiag1) samepos(hdiag1);"
before the dcl-ds set_diag... line.

Trial and error got me that before (as in my original posting).

Haven't got time to try it Duane, but this should be all you need.

Just the file definition and this:

dcl-ds ar_hst1 extname('HISTORY1' : 'HST1') qualified;
dcl-ds set_diag dim(18) samepos(hdiag1);
hdiag like(hdiag1);
hdiagpoa like(hdiag1poa);
end-ds;
end-ds;

Jon,

Here's a portion of the dds for the file. CDIAG is 8 bytes character, CPOA is 1 byte character

A HDIAG1 R TEXT('DIAGNOSIS 1')

Can you show an extract from the actual record layout Duane - I'm having trouble visualizing what you're trying to do.

Barbara (or other excellent explainer),

This is a great feature. Except it's not working as I imagined it and as Jon Paris "exampled" it in his article in The Four Hundred: Guru: 7.4 Brings New RPG Goodies.

I've tried to work this one in on my 7.3 and am having a difficult time adjusting it to work.

My example tries to redefine a record format where 18 sets of an 8 byte character followed by a 1 byte character:

dcl-f history1 usage(*input); // rcdfmt(hst1)
dcl-ds ds_hst1 likerec(hst1) ;
dcl-ds ar_hst1 extname('HISTORY1' : 'HST1') qualified;
diag1_set like(hdiag1) samepos(hdiag1);
dcl-ds set_diag dim(18)
samepos(hdiag1);
hdiag like(hdiag1);
hdiagpoa like(hdiag1poa);
end-ds;
end-ds;

when compiling, I get:
RNF3523: External description SET_DIAG for data structure is not found; data structure is ignored.

My outline (RDi) shows that SET_DIAG has the correct elements.

I did get it to work as advertised on a single field array.

Any suggestions?

The one thing this one can't do easily Joe is to create an array from non-contiguous fields - that you'll still have to use the DS/Overlay approach for.

If they were all the same distance apart, you could define a data structure array with all the repeated fields.

dcl-ds ds;
x char(5);
a1 packed(3);
b1 char(5);
a2 packed(5);
b2 char(5);
a3 char(5);
b3 char(5);
dcl-ds a_b_array dim(3) samepos(a1);
a like(a1);
b like(b1);
end-ds;
