Effect

Simulates an error that is specified by its code.

Syntax

ERROR <ErrorNumber>

Parameter

<ErrorNumber> can vary between 1 and 255. As MSX-BASIC uses values 1 to 25 and Disk BASIC values 50 to 81, you can use the non-defined values to generate specific error messages in your programs. Variables are not usable.

Example

10 ON ERROR GOTO 400
20 INPUT "X= ";A
30 IF A>100 THEN ERROR 150
40  IF A<10 THEN ERROR 151
50 END
400 IF ERR=150 THEN PRINT "MAXIMUM 100!"
410 IF ERR=151 THEN PRINT "MINIMUM 10!"
420 RESUME 20
430 ON ERROR GOTO 0
