Labels

Identifier :

A label indicates a target for the GOTO instruction.

A label is local to a function or procedure.

GOTO and labels can be used to leave a control structure.

FOR iY = 0 TO 5
  FOR iX = 0 TO 20 STEP 1
    PRINT "Loop1 "; iX
    IF iX = 3 THEN GOTO LOOP2
  NEXT
NEXT
LOOP2:

But GOTO and labels cannot be used to enter a control structure. This is forbidden, even if the variables are preset.

iX = 18
' GOTO LOOP3 ' forbidden
FOR iX = 20 TO -2 STEP -2
LOOP3:
PRINT "Loop2 "; iX
NEXT
