JCL RTN

Man Page Index

Terminates execution of an external subroutine and returns control to a statement following the [ ] command that called the subroutine.

SYNTAX

RTN{n}

SYNTAX ELEMENTS

n specifies that control should be returned to the n'th statement line after the calling [ ] command. Can be a number, or a direct or indirect reference to a buffer or select register.

NOTES

If n is not specified, control will return to the statement immediately following the calling [ ] command.

A RTN without a corresponding [ ] command will terminate the program.
