Hi,
I would like BS2 code to ignore any values say between values -10 to +10
I have posted my code which appears to work below, but is this the correct way to go about this?
Thanks

' {$STAMP BS2}
' {$PBASIC 2.5}
' This code ignores any values between limits -10 to +10
x VAR Word
x = -9 'Change these test values
Main:
IF (x > -10) XOR (x < 10) THEN x = 0
DEBUG SDEC x,CR
GOTO Main

    Veitch,

    Welcome to the forum!

    Your code will set x to zero if it's inside the interval (-10 .. 10), excluding -10 and 10. Is that what you want? If so, that's a very clever way to do it. :)

    BTW, when posting code ...

    How about,
    IF ABS X < 10 THEN x=0
    ?

    Sure, that works, as long as the upper and lower limits have the same absolute magnitude. :)

    Phil and Tracy thanks for your help.

    I expect there must be several ways to do this.
    I'll use the shorter version suggested.

    Regards

    You can always rest assured that Tracy is the Man when it comes to BASIC Stamp math -- among many other things! Be sure to stop by his website for more insightful Stamp stuff:
