O It is a data name
O It is a figurative constant
O It is a condition name
O None​

Answer 1

Answer:

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 procedures is completed.

The PERFORM statement is:

An out-of-line PERFORM statement

When procedure-name-1 is specified.

An in-line PERFORM statement

When procedure-name-1 is omitted.

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, imperative statements and the END-PERFORM phrase must not be specified.

The PERFORM statement formats are:

Basic PERFORM

TIMES phrase PERFORM

UNTIL phrase PERFORM

VARYING phrase PERFORM

Basic PERFORM statement

The procedures referenced in the basic PERFORM statement are executed once, and control then passes to the next executable statement following the PERFORM statement.

Note: A PERFORM statement must not cause itself to be executed. A recursive PERFORM statement can cause unpredictable results.
