Yes you right!
Let figure out for example if I want to process 50,000 statements and one field name tray have the number 1,2,3 or 4 for selecting the right tray and each tray have a special form preprint and color with different credit card ect., what will be the process to generate only one spool file or print to a file.prn.
Maybe you have the solution I am thinking too much.

EXP:
select myTable
scan
do case
case myTable.tray = 1
store sortkey to msort
set printer to name Prntray1
REPORT FORM myreport.frx for sortkey = msort while sortkey =msort TO FILE myReport.prn NOCONSOLE

case myTable.tray = 2
store sortkey to msort
set printer to name Prntray2
REPORT FORM myreport.frx for sortkey = msort while sortkey =msort TO FILE myReport.prn NOCONSOLE

case myTable.tray = 3
store sortkey to msort
set printer to name Prntray3
REPORT FORM myreport.frx for sortkey = msort while sortkey =msort TO FILE myReport.prn NOCONSOLE

case myTable.tray = 4
store sortkey to msort
set printer to name Prntray4
REPORT FORM myreport.frx for sortkey = msort while sortkey =msort TO FILE myReport.prn NOCONSOLE
