The actual code uses DoU.

Hi Rick

Does that work?  The loop will never be executed because 1
will never be equal to -1 and a DOW tests the condition at
the start of the loop.  DOU, on the other hand would execute
the loop until told to leave.

Personally I tend to use either of the following depending on
how my mood takes me:

     D True            s               n   Inz(*On)
     D False           s               n   Inz(*Off)
                                                   
     C                   DoW       True            
     C                   If        Condition = Met 
     C                   Leave                     
     C                   EndIf                     
     C                   EndDo                     
                                                   
     C                   DoU       True = False    
     C                   If        Condition = Met 
     C                   Leave                     
     C                   EndIf                     
     C                   EndDo                     

IN some ways I think the second example is better because it
makes you look twice at the line and take note that it's a
DOU and not a DOW.

 I'm curious.  I use a loop similar to the one below to place
the program into a wait state until a condition is met.  In
this case, entries have been remove from a data queue so it's
save to add another one.  It prevents the program from
overflowing the data queue.  It is prefaced with several
lines of comments explaining why the loop is there.

      DoW 1 = -1
              If data queue is not full
                      leave
              EndIf
      EndDo

If this isn't the way one should do this kind of thing, how
should it be done?

Rick

Ok...  let me explain.
I'm running a test on emailing pdf's.  That section of code deletes
the spool file after it's sent.  I don't want the spool
file deleted
because for now I want to manually do stuff to it.  Once
I'm done, I'm
removing the if statement.
I don't want to comment out the section of code cause I
don't want the
date to change on the code line because it's not really changed.  I
would never ever stick a line of code in like that if it
was going to
production.
