ok, here's a quick, simple funtion that is just designed to make x# equal to one.

+ Code Snippet

do
cls
aim(x#)
text 10,10,str$(x#)
loop
end
function aim(x#)
x#=1
endfunction x#

...But, here's the thing. My screen always returns a zero as a value for x#. Could this be a bug, because I'm stumped. Even better, could someone send me a SHORT code with a simple function in it and tell me what it does on your computer so i can see if it works on mine?

When you use variables in functions they are local to only the functions meaning x# equals 1 in the function but not in the entire program. You would have to either global x# by doing something like global x# or use an array which are always global.

Also the # means float and you don't need it if your not going to use floats and only integers.

Hope that explains things

thanks slayer!

I used this code...

+ Code Snippet

do
cls
aim(x#)
loop
end
function aim(x#)
x#=1
text 10,10,str$(x#)
endfunction x#

...and it works perfectly!

Or you could do it like this...

+ Code Snippet

do
 cls
 text 10,10,str$(aim(0))
loop
end

function aim(x#)
 x#=1
endfunction x#

Further on my stuff at...
