GOTO Keyword

GOTO numeric-constant

Transfers control unconditionally to the line with the given constant line number in the current program.

Remarks

Deprecated / discouraged.

Prefer structured flow control and procedures:

IF,

WHILE/ENDWHILE,

REPEAT/UNTIL,

FOR/NEXT,

and DEF PROC.../ENDPROC with PROC calls.

• The target must be a numeric constant; variables or expressions are not allowed.
• Jumps may be forward or backward within the same program.

Examples

Forward jump

10 PRINT "Start"
20 GOTO 100
30 PRINT "This line is skipped"
100 PRINT "Landed at 100"

Simple loop with GOTO

10 I = 1
20 PRINT I
30 I = I + 1
40 IF I <= 5 THEN GOTO 20
50 PRINT "Done"

Notes

• Jumping to a non-existent line raises a runtime error.
• Heavy use of GOTO quickly reduces readability; use it only for compatibility with legacy code.
