Subroutine Control Commands › CALL

CALL

Purpose

Passes control to a predetermined subroutine.

Syntax

►►─── CALL subroutine-name ──── . ────────────────────────────────────────────►◄

Parameter

subroutine-name

Specifies the 1- to 8-character name of the subroutine to which control is passed. The subroutine name is defined by the DEFINE command, described below.

Usage

When the CA ADS runtime system encounters a CALL command, processing control passes to the beginning of the named subroutine. Processing continues through the subroutine until CA ADS encounters a GOBACK command, or a control command

If no GOBACK or control command occurs before the end of the subroutine, the runtime system automatically returns control to the command that immediately follows the associated CALL command.

Considerations

• A CALL statement can occur in the body of a process or within a subroutine definition.
• Subroutine calls can be nested up to ten levels.
• The called subroutine must be defined by using the DEFINE command, described later in this section, and must be coded later in the process than the CALL command.
