Re: trimming non-numerics

[Raul A Jager <raul@xxxxxxxxxx>]

   The first two bytes of the field contains the length, so I imagine the
   compiler can replace the call to the BIF with a reference to the address
   in memmory, just like if it was a numerical variable.

 I would think if you are removing characters, then you are changing the
 length of the string.  As such, some form of checking it every iteration
 would be required...

 Just a thought,

 Hans,

 I notice in your FOR loop you are evaluating the length, %len(source), each
 time through the loop.
 is it necassary to call the bif each time? ... I notice Cozzi is doing the
 same thing.

 Jeffrey,
 The article I was talking about is at this link. It does the job and has
        

 the
    

 source that you can cut/paste into your editor of choice.

 Bob: That link doesn't seem to work. Either it's because mcpressonline
 uses malformed URL's that get mangled by the mailing list software, or
 it's because I'm too lazy to register for the site, but it shows blank
 content for me. Could you post your code to the mailing list so we can
 compare it to the code I posted earlier?

 In case you missed it, here's the code I posted earlier:

 ------------------------------------------------------------------
 D i               s             10i 0
 D source          s             50a   varying
 D target          s             50a   varying
   /free
      source = 'jafgjh934hdfg94k3ghsd0jdfg0345jdfg';
      target = '';

      // Extract digits out of source string
      for i = 1 to %len(source);
         if '0' <= %subst(source:i:1) and %subst(source:i:1) <= '9';
            target += %subst(source:i:1);
         endif;
      endfor;

      // Display results
      dsply source;
      dsply target;
      *inlr = *on;
   /end-free

 Cheers! Hans
