I'm writing a program where you have to press either the 1,2,3, or 4, and then a different message is supposed to display according to each different button press.

How would I go about this? Programming the keyboard has ALWAYS been rather difficult for me. I think this'd have something to do with scan codes, but not positive... and if I'm right, how to make this work. Help would be appreciated.

Thanks!!

you could use keystate() function which requires the scancode as a param

here's the scancodes


KEYSTATE
This command will return an integer value of one if the key specified by the scancode is pressed, otherwise
zero will be returned. The scancode value is the raw value assigned to the key of the keyboard device and
very often is ordered sequentially from the top left of the keyboard to the bottom right.

SYNTAX
Return Integer=KEYSTATE(Scancode)

I appreciate it, cattle rustler, and I thought the keystate would work too, and it probably WILL, however.... since this is totally text based, I've thrown in a bunch of wait keys to hold my screens and.... well..... I'll go ahead & show you the code.
I don't have a wait key command thrown in this bit of code, no... but when it gets down to that very last print command, it's like you don't even see it, and the program ends. better yet... if you like, I can send you the full executable as far as I've gotten through email.

replace the last print command,
print "to choose your clan, fledgling, press a number 1-4"

with this:
