MESSAGESUB statement

Syntax: MESSAGESUB statement-label

Discussion: The MESSAGESUB statement sets a branch-to address for the current program. If this program is interrupted while running (via an INTERRUPT statement from another program), program flow will be transferred to the statement-label specified in the MESSAGESUB statement.

When a RETURN statement is executed after the MESSAGESUB path has been taken, program flow continues at the statement immediately following the statement where the INTERRUPT occurred. 

Example:  MESSAGESUB 9999        ! Set MESSAGESUB label
.
.
.
9999   MESSAGESUB 9999 ! Reset MESSAGESUB label
      RETURN
