It is a report generation program.
I want to know how to improve the performance of a program.

Specifiaction is like this
A page contain not more then 3 records
if fld1 value changes(suppose it is dept) if dept changes then sum total pergformed.
Input have a field called grade which may be 1 or 2.
We have to print the report for grade 1 and then for grade 2.
When report for grade 2 is tro be printed slno should be started with 1.
In file format (sortyec in emp no and dept). No need to use sorting)

learnmf,
millions records in array will always create some performance issues.
try visiting your cobol programming basics one more time. you will find the answer....
