RETURN

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 is produced.
• To avoid errors, place GOSUB procedures AFTER the main program code END or after an EXIT SUB or EXIT FUNCTION call.

Example(s)

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 

 1
 2
 3
 4
 5
Aha! Five!
 6
 7
 8
 9
 10

Returns to a specific line label.

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

hey: 
RETURN hoho 

it went here.
