I've done something similar to the following to avoid hard coding the POS() value when using a subfield. We have files that have 12 date fields and I often create an array over them for easier processing.
dcl-ds CHA extname('CHNLANALP') qualified end-ds;
dcl-s FieldPtr pointer Inz(%Addr( CHA.Field01 ));
dcl-s FieldArray like(CHA.Field01) dim(32) Based( FieldPtr );

EXTNAME brings in the external columns, so that won't allow you to make an array. My thought was to manually define your DS, rather than use EXTNAME. Plan B would be to define a second DS and just move your I/O DS to/from the second DS.

Thanks for the reply Justin
The answer to your question is - I don't know Im having a complete moronic time at the moment
I have a file called CHNLANALP that has this dcl-ds CHA Extname('CHNLANALP') qualified end-ds; In the program The last 32 fields on this file need to be redefined as Indfield DIM(32)
But I just cannot see what I need to do
Hope that makes sense

Assuming you're asking about RPG, can't you just define you I/O data structure to contain an array?

Hi everyone
Before I forget - we are on V7r1
Here is my situation - hope that it makes sense
I have defined a file where the last 32 fields on the record are all the same size Fields 1 through 31 represent the day of the month, with field 32 being the total of fields 1 through 31
How can I define these fields within my program (using new free-form) so that these 32 fields are an array That way, I can use the day of the month to determine which occurrence I need to deal with
Like I said - I hope my question makes sense
As always - all answers gratefully accepted
