Re: Problem with spool.

My first thought is to write the information to a temporary file in QTEMP.
Multiple occurring data structures may work too. In other words, save the
information you need to write until you determine if you need to write it -
if you do need to write it, write it.

Hi

My problem is regarding "saving" spool in some "place" and than decide if
print it realy or not. I'll try to describe it more precisly.

When I calling report program do following functions:
1) Write header record (say 5 lines)
2) Detail calculations
3) Write detail record (say 2 lines)
4) Total calculations
5) Write total record (say 3 lines)

And problem is that only during 4-th point - total calculations I got all
data based on them I can decide if record/point 1/3/5  shold be or
shouldn't
be realy write to finally spool/printout.

The easiest way is reorgenize processing:
2) Detail calculations
4) Total calculations
6) check condition and
1) Write header record (say 5 lines)
3) Write detail record (say 2 lines)
5) Write total record (say 3 lines)

But this way not always is possible to do.

So my question is how to write record into some temporary "space" - all
three records and than move them back to finally spool in order:
1) Write header record (say 5 lines) (into temporary space, complete 5
lines)
2) Detail calculations
3) Write detail record (say 2 lines) (into temporary space, complete 2
lines)
4) Total calculations
5) Write total record (say 3 lines) (into temporary space, complete 3
lines)
6) check condition and
7) Write header record/move from temporary space into finally spool
8) Write detail record/move from temporary space into finally spool
9) Write total record/move from temporary space into finally spool
