ABSTRACT
A procedure is a set of instructions that perform a specific task. They are invoked from another procedure — the calling procedure (or program) — and provide results to the calling program at the end of execution. Procedures (also called subroutines) are utilized primarily for routines that are called frequently by other procedures. The procedure routine is written only once, but used repeatedly; thereby, saving storage space. Procedures permit a program to be coded in modules; thus, making the program easier to code and test.
