The PERFORM statement transfers control explicitly to one or more procedures and implicitly returns control to the next executable statement after execution of the specified procedure(s) or imperative statements is completed.
An in-line PERFORM must be delimited by the END-PERFORM phrase.
The in-line and out-of-line formats cannot be combined. For example, if procedure-name-1 is specified, the imperative-statement and the END-PERFORM phrase must not be specified.
