RETURN is used in GOSUB procedures to return to the original call code line or a specified line label.

Syntax

: RETURN [{linelabel|linenumber}]

Parameter(s)

  • RETURN without parameters returns to the code immediately following the original GOSUB call.
  • line number or linelabel after the RETURN statement returns code execution to that label.

Usage:

  • Normally required at the end of a GOSUB procedure unless the procedure returns using a loop.
  • RETURN is not used in error handling procedures. Error procedures use RESUME line number or RESUME.
  • GOSUB procedures use line numbers or line labels designated with a colon after the number or label.
  • If RETURN is encountered without a previous GOSUB call a [ERROR Codes](ERROR Codes) is produced.
  • To avoid errors, place GOSUB procedures AFTER the main program code END or after an [EXIT SUB](EXIT SUB) or [EXIT FUNCTION](EXIT FUNCTION) call.

Example 1: Returns after a Gosub.

FOR a = 1 TO 10
PRINT a
IF a = 5 THEN GOSUB five
NEXT
END       'END or SYSTEM stop the program before the execution of a sub procedure

five:
PRINT "Aha! Five!"
RETURN

Example 2: Returns to a specific line label.

PRINT "it didn't go here." 
hoho: 
PRINT "it went here." 
END
