Re: [EXTERNAL] RE: File having an array using new free form -- RPG400-L

It should work - as long as you can count! - but I prefer the solution I offered on the Midrange list and Birgitta has offered here.

Using Pos values of anything other than 1 - other than on things like the PSDS - is risky. This program will break big time with a change in field length of any of the fields in the first 96 bytes.

Repeat after me - hard coding bad - soft coding good!

WOWWWWW
Thanks Birgitta - I believe I have it
Well - I mean - there are no compile errors

OMG - that was a struggle

This is what I ended up with

I have the external file defined

dcl-f Chnlanalp usage(*output:*update) keyed prefix('CHA.');

Then it is qualified later

dcl-ds CHA Extname('CHNLANALP') qualified;
Arr Like(CHA.Camtday01) Dim(32) Pos(97);
end-ds;

Where the field Camtday01 starts in position 97 in the record

The proof of the pudding will be in the testing

Fingers (and anything else) crossed

Appreciate all the responses

Define a Data Structure, list all the file fields as subfield and overlay it with an array:

DCL-DS YourDatastructure
FileFld1;
FileFld2;
FileFld3;
...
FileFld32;
Arr Like(FileFld1) Dim(32) Pos(1);

Hi everyone
Before I forget - we are on V7r1
I have also posted this question on the Midrange Systems Technical Discussion side

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
