Re: Variable Numeric return from procedure

John:

Do you want a rpg or cl to do this convertion?  This goes back to the wish I
made about a Value function.  Enclosed is the suggestion that I recieved.

You already have that capability, in a way.  Try out the following RPG
program:
     H dftactgrp(*no) bnddir('QC2LE')
     D atol            pr            10i 0 extproc('atol')
     D                                 *   value options(*string)
     D num             s             10i 0
     C                   eval      num = atol('1234')
     C     num           dsply
     C                   eval      *inlr = *on
The trick here is that function "atol" is part of the C run-time library,
which is shipped on every AS/400.  So basically, consider every routine
defined in the C run-time as available to you! (Yeah, I know.  You'd rather
have a built-in function for this.)

Cheers!  Hans.
