Re: Looking Up a Data Structure Array

I have. Won't compile. This is just a little source member I have for
testing snippets of code. I've tried the complete ds+subfield, just the ds
and just the subfield. None will compile.

Thanks,

Mark

Sounds doable.

Two items of concern here.
1)  Your 10 count do loop is going to run into a truncation error on the
10th element.  (1 character field).  Unlike previous versions of RPG I
wouldn't assume 0.
2)  Your first data structure subfield should not have a *next in it.

You've got your code this far now.  Why not test it?

Re: Looking Up a Data Structure Array







No,

More like this:

 ddsArray          DS             1    dim(10) qualified
 D dsChar                         1    overlay(dsArray:*next)
 DdsIdx1           s             10u 0
 DdsIdx2           s             10u 0

 D/copy *libl/qrpglesrc,cvtdatepr
  /free

    for dsIdx1 = 1 to 10;
      dsArray(dsIdx1).dsChar = %char(dsIdx1);
    endfor;

    dsIdx1 = 1;
    dsIdx2 = %lookup('4':dsArray.dsChar:1);
    dsply dsIdx2;
    return;

I'd like to find a matching entry in a DS Array subfield.

Thanks,

Mark

Is it possible to look up a data structure array subfield?
