Perform verb in COBOL is used to execute a set of COBOL statements. There are some set of statements in a program that needs to be executed repeatedly, such as reading each record of a file up to its end. The statements in the program are running in a series until or unless if any ...
It performs a set of Cobol statements between Perform & END-Perform. Basically this is to keep a particular logic in a boundary and execute it in a loop or number of times or execute depending upon a condition. This is useful if that set of code is only used once in thAT program. If...
An approach to selecting statements for inlining in a COBOL program involving creating a PERFORM Graph (PG), determining whether the PG is a Directed Acyclic Graph (DAG), responsive to determining the PG is not a DAG, identifying a maximum sub-graph DAG corresponding to the PG, computing one...
The PERFORM command transfers control explicitly to one or more statements and implicitly returns control to the next executable statement after execution of the specified statements is completed. The keywords cannot be abbreviated. Simple: PERFORMcommandEND-PERFORM; command A valid z/OS® Debugger ...
