RE: trimming non-numerics

["Bob Cozzi" <cozzi@xxxxxxxxx>]

Hans,

Here's what I've got now... works great!

  for       i = 1 to %Len(szInValue)
    eval      ch = %subst(szInValue:I:1) 
          if        memchr(%addr(SaveMe)+2:CharInt:%len(SaveMe))<>*NULL
             eval      CleanVal = CleanVal + %subst(szInValue:I:1) 
          endif                   
  endfor                       
      //  Return the clean number to the caller, as text.
  return    CleanVal

-Bob

Joe: If you're concerned about performance, then do some performance 
testing on the alternatives.

But in this case, storing the length in some integer variable wouldn't 
buy much since %LEN(SOURCE) is not a performance hog. It simply does a 
load of the first two bytes of the character varying variable.

Cheers! Hans
