1. Branch to the label line corresponding to the value of the expression
   ON Expression GOTO @Label0,@Label1…
2. Branch to the label line corresponding to the value of the expression and return to the next command after ON GOSUB by using the RETURN command
   ON Expression GOSUB @Label0,@Label1…
3. Register the jump destination when the user tries to stop the program
   ON BREAK GOTO @Label

1. Branch to the label line corresponding to the value of the expression

ON Expression GOTO @Label0,@Label1…

Arguments

Expression

The jump destination is selected according to the value of the expression written here.

・The value must be numeric.

@Label0

Jump destination when the value of the expression is 0

@Label1

Jump destination when the value of the expression is 1

・Prepare as many destinations as you need.
・Strings cannot be used for the ON to GOTO labels.

Example

ON IDX GOTO @JMP_A,@JMP_B
PRINT OVER:END
@JMP_A
PRINT "IDX=0":END
@JMP_B
PRINT "IDX=1":END

2. Branch to the label line corresponding to the value of the expression and return to the next command after ON GOSUB by using the RETURN command

ON Expression GOSUB @Label0,@Label1…

Arguments

Expression

The jump destination is selected according to the value of the expression written here.

The value must be numeric.

@Label0

Jump destination when the value of the expression is 0

@Label1

Jump destination when the value of the expression is 1
:
・Prepare as many destinations as you need.
・Strings cannot be used for the ON to GOSUB labels.

Example

ON IDX GOSUB @SUB_A,@SUB_B
PRINT EXIT:END
@SUB_A
PRINT "IDX=0":RETURN
@SUB_B
PRINT "IDX=1":RETURN

3. Register the jump destination when the user tries to stop the program

ON BREAK GOTO @Label

・If you press the + Button during program execution, the program will normally stop. But, you use ON BREAK GOTO to jump to the specified label.
・Once you jump to the registered label, the registration is canceled.
・If the program stops due to an error, TRACE,STOP execution, forced stop by pressing + Button, programs start from the Top Menu, etc., it will not jump even if a label is registered.

Argument

@Label

Jump destination when program stops

Example

ON BREAK GOTO @FINISH
LOOP
ENDLOOP

@FINISH
PRINT "Stopped!"
