write a subtotal line.
reinitialize any counters or totals.

LOOP-PARAGRAPH.
(statements that process the current record)
read the next record.
if the value of the break field has changed
or end-of-file
perform the control break.
if not end-of-file
save the value of the break field.

END-OF-JOB-PARAGRAPH.
close the files.

CONTROL-BREAK-PARAGRAPH.
write a subtotal line.
reinitialize any counters or totals.

Control Break with Page Break

           INITIALIZATION-PARAGRAPH.
open the files.
move 1 to the page number.
print the headers.
do the initial read.
save the value of the break field.

LOOP-PARAGRAPH.
if value of break field has changed
perform the control break.
if the detail line count > page break value
print the headers.
(statements that process the current record)
add 1 to the detail line count.
save the value of the break field.
read the next record.

END-OF-JOB-PARAGRAPH.
perform the control break.
close the files.

PRINT-THE-HEADERS.
write the header lines.
increment the page number.
reset the detail line count back to zero

CONTROL-BREAK-PARAGRAPH.
