Tandy 1000 Basic Reference Manual

Chapter 10 I BASIC Keywords
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, an error occurs because the
loops were left incomplete.
If the program encounters a RETURN statement without execu-
tion of a matching GOSUB, an error occurs.
Example
RETURN 40
returns from the subroutine to Line 40 in the program.
Sample Program
330 PRINT "THIS PROGRAM FINDS THE AREA OF A
CIRCLE"
340 INPUT "TYPE IN FI VALUE FOR THE RADIUS"; R
350 GOSUB 370
360 PRINT "AREA IS" ; A: END
370 A = 3.14 R * R
380 RETURN
294
