[WEB400] Re: HTTP Jobs hanging up

["Bob Cozzi" <cozzi@xxxxxxxxx>]

Are you at EOF? The field will not be cleared if that's what you're
expecting? How about adding  if %EOF(CAFPMAST);
 leave;
Endif;

To the loop.

Oh, and stop using the free-form stuff... You'll go blind!  :)

Thanks to everyone who has responded to this: with Scott's help I was able
to break into the running job in debug and find where the endless loop is
occuring, but it makes no sense to me.

Here is the loop:

dow MLNAM = NAMEIN; 
  if MMAP = LASTMAP;
    read cafpmast;  
    leave;          
  endif;            
  read cafpmast;    
enddo;              

MLNAM is the field from the file and there is only one record in the file
with this name.  In debug I can see the read statement processing, but it
never moves to the next record, so the field value cannot change.

After EVERY read I get the same MLNAM and MMAP (both fields from cafpmast),
so I never get out of the loop.  How can this be???  

Thanks,

Joel
