I'm fairly new to using darkBASIC and was wondering if anybody could tell me the keyboard controls (e.g. if controlkey()) for the + and - buttons.

And if it wasn't any trouble; does anybody have an entire keyboard control list?

-Thanks in advance

go into the help files, go to the command section and in the input section select the return value=scancode() command

view this help file, it works well

There are only 10 kinds of people in the world, those who understand binary and those who dont

I forget who made this, but it is an excellent pic for showing the keyboard values using the KEYSTATE command.

Every key on your keyboard is mapped out like LBFN's pic, even if some of your keys have different symbols on them to the ones in the pic that doesnt matter, it is the position of the keys the numbers are assigned to.

The keystate command will tell you the state of any key on the keyboard (1=pressed 0=up), all you have to do is supply the function with the number that represents the key you want to check. i.e. keystate(12) would return the state of "-" and keystate(13) of "+".

I'm guessing you are using these keys to increase/decrease a variable; because of the speed at which the computer executes your code it is near impossible to register a single key press, for this you will have to write your own routine.
A simple switch can be implemented like so...

[sorry text limit have to double]
By storing the old inputs before we get the new input we can analyse the change in input.
Only if the key is pressed and wasn't pressed before will the program perform the inc/dec action. INC and DEC stand for increment and decrement (or increase decrease if thats easier), they give a quick way to adjust a variable; by default they will adjust by 1 but you can supply a value: i.e. INC x,5

Hope this helps.
