RE: Unwanted loop with %SCAN and %REPLACE

["DeLong, Eric" <EDeLong@xxxxxxxxxxxxxxx>]

Peter,

Your loop is testing ITCLS for an embedded '0', but when you replace the
'0', you assign the new string to a new varible.  ITCLS remains unchanged,
and will loop forever.....

Hi list!

Why this is getting into a loop?  I pulled this from the archives for a
similar
situation I have but apparently I am doing something wrong...

D ITCLS           s              4a   Inz('G08')
D BITACL          s              3a

 /Free
     Dow (%scan('0': ITCLS) > 0);
       BITACL = %replace(''  : ITCLS: %scan('0': ITCLS): 1);
     Enddo;
     *InLR = *On;
 /End-Free

TIA!
