RETURN Statement
Purpose:
To return from a subroutine.
Syntax:
RETURN [line number]
Comments:
The RETURN statement causes GW-BASIC to branch back to the statement following the most
recent GOSUB statement. A subroutine may contain more than one RETURN statement to return
from different points in the subroutine. Subroutines may appear anywhere in the program.
RETURN line number is primarily intended for use with event trapping. It sends the eventtrapping
routine back into the GW-BASIC program at a fixed line number while still eliminating
the GOSUB entry that the trap created.
When a trap is made for a particular event, the trap automatically causes a STOP on that event so
that recursive traps can never take place. The RETURN from the trap routine automatically does an
ON unless an explicit OFF has been performed inside the trap routine.
The non-local RETURN must be used with care. Any GOSUB, WHILE, or FOR statement active at
the time of the trap remains active.
