RETURN
Statement
RETURN
[Line]
Returns control to the line immediately following the most re-
cently executed GOSUB.
Line
tells BASIC to return to a specific line in the program. If
you omit
line,
BASIC goes to the line immediately following the
GOSUB.
Use caution when specifying a line number with RETURN. Any
other GOSUB, WHILE, or FOR statement remains active while
a GOSUB subroutine is executing. If BASIC returns to a line
number that is outside these loops, a n error occurs because the
loops were left incomplete.
If the program encounters a RETURN statement without execu-
tion of a matching GOSUB, a n error occurs.
Example
RETURN 4 0
returns from the subroutine to Line 40 in the program.
