EXITTO statement

Syntax: EXITTO level-number [,EXCP=statement-label]

Discussion: The EXITTO statement returns control to the calling program at the specified level-number.

Level-number is a numeric constant or varaible (length/precision = 2.0) equal to the value of the ENTERLEVEL system variable to which you wish to exit.

For example, if a subprogram is running at level 5 (i.e., ENTERLEVEL = 5) and wants to return to level 2 (i.e., ENTERLEVEL = 2), the following statement would be used:

EXITTO 2
