Try ATOLL() as I suggested.

Oops.  Thanks for catching that.  I also notice that in the atoi method,
I declare the num as 10s 0 instead of 10i 0.  Redo and rerun and result
are below 

%dec takes 8 secs.
%int takes 12 secs.
atoi takes 8 secs.

%int method ==>
D char            s             10    inz('12    ') 
D num             s             10i 0

Lim - unless it was a typo on your part, you may want to re-run the
stats for %dec Please see your code for %dec below

Looks like %dec is the winner.  Execute the conversion for 10M times 
and below are result:

%dec takes 4 secs.
%int takes 12 secs.
atoi takes 9 secs.


Below are coding:

%dec method ==>
D char            s             10    inz('12    ')
D num             s             10s 0
D myIx            s             10s 0

 /free

   for myIx = 1 to 10000000;
      num = %dec(num :10 :0);
   endfor;

   *inlr = *on;

 /end-free



%int method ==>
D char            s             10    inz('12    ')
D num             s             10i 0
D myIx            s             10s 0

 /free

   for myIx = 1 to 10000000;
    num = %int(char);
   endfor;

   *inlr = *on;

 /end-free



Atoi method ==>
H DFTACTGRP(*NO) BNDDIR('QC2LE' :'AHBNDDIR')
D char            s             10    inz('12    ')
D num             s             10s 0
D myIx            s             10s 0

D atoi            PR            10i 0 extproc('atoi')
D  pValue                         *   value options(*string)

 /free


   for myIx = 1 to 10000000;
      num = atoi(char);
   endfor;

   *inlr = *on;

 /end-free

left

justified (contains tailing blanks) and could contain all blanks.

atoi?

D atoi            PR            10i 0 extproc('atoi')
D  pValue                         *   value options(*string)
