Re: Printing from a Subfile

May I ask a simple question that isn't clear to me.  The for loop is defined
to run for the size of the subfile.  So, why is there a not %found loop?  By
definition, this can never occur, right?  And if it does, so what? 
 
Also, a sort of sideways question:  Does the overflow indicator get set off
when the heading is printed?  Must we code it?

Hello,
 
You can't use the record format name as the parameter to %EOF(), and in
any case, the CHAIN opcode doesn't turn on %EOF, it turns on %FOUND if a
record is not found.  I suggest coding it more like this:
 
write heading;
prtoverflow = *off;
 
for RRN = 1 to HighRRN;
 
     chain RRN KDSDATA;
     if not %found;
        iter;
     endif;
 
     if prtoverflow;
         write footer;
         write heading;
         prtoverflow = *off;
     endif;
 
     write detail;
 
endfor;
 
write footer;
 
The "HighRRN" field is something that you save when you load the subfile
to keep track of the highest RRN that you loaded.  That way, you can
easily loop through the subfile.
