You in a class or something? Are they still teaching COBOL in schools?

PERFORM "calls" a routine (or routines) for processing.
Examples:

PERFORM myRoutine.

PERFORM calculate THRU update.

PERFORM readRecords

This one too:

Perform m00-month-rtn thru m99-exit
varying msub from 1 by 1
until msub > 12
end-perform.

You'd get faster answers if you'd read your textbook.
