RE: Web apps on the AS/400

[Buck Calabro <buck.calabro@xxxxxxxxxxxxxxxxx>]

RPG: Code time: 5 minutes.  Run time: 1.5 sec.  Same 620 environment as
before.  I used a different approach <grin>  This works for the empty string
too.

d theString       s             50    inz('     this_is_a_test      ')
d theResult       s             50                   
d loopLimit       s             10u 0 inz(100000)    
d timestp         s               z                  
                                                     
c                   time                    timestp  
c     timestp       dsply     'BUCK'                 
c                   do        loopLimit              
C     ' ':x'fe'     xlate     theString     theResult
C     '_':' '       xlate     theResult     theResult
C     x'fe':' '     xlate     theResult     theResult
c                   enddo                            
c                   time                    timestp  
c     timestp       dsply     'BUCK'                 
                                                     
c                   eval      *InLR=*On
