Do Loop Problem

Do Loop Problem

Do Loop Problem

The first record of the SAC has PO# 12345 and Item: ABCDE.

The ex_850dtly file has 2 records with that PO and Item combination.  However, it seems to ignore the "dou not %found(ex_850dtly)" command and goes through the loop the 3rd time.  when it hits the UPDATE, it bombs out.

What am I doing wrong?

Here is the code:

   read ex_850sac;                                   
   dou %eof(ex_850sac);                              
     setll (edsacpo:edsacitm) ex_850dtly;            
     reade (edsacpo:edsacitm) ex_850dtly;            
     dou not %found(ex_850dtly);                     
       item = %subst(edpo107:1:6);                   
       color = %subst(edpo113:1:2);                  
       if %subst(edsacupc:2:5) = %subst(edpo107:1:5);
         size = '000';                               
         size = %subst(edpo113:3:3);                 
       edpo118 = 'IS';                               
       edpo119 = item + '-' + color + '-' + size;    
       edpo120 = 'MU';                               
       edpo121 = edsacupc;                           
       update edformat;                              
       reade (edsacpo:edsacitm) ex_850dtly;          
     read ex_850sac;                                 
   *inlr = *on;                                           

RE: Do Loop Problem


dow not %EOF(ex_850dtly)

The dow will prevent entering the loop in case there are records with that key in ex_850dtly.

The setll uses %found to tell you that an equal key exists. But, when you issue the reade, then you need the %eof for the do loop.

RE: Do Loop Problem

The difference between DOU and DOW is that DOU always esecutes a loop at least once. Therefore, hou have to check the condition at the top of the loop (but you only need one READ or READE).

A DOW loop does not execute at all if the condition isn't met, and you need two READs or READEs.
