I am using an input array (lets just say it's text) and as I scroll from line to line as I input the text this increases my max line count.
I want
Code:

---

vslider = x, y, len, bmap, min, MAX, var;

---

my max to be a variable based on how many lines I have in my array.
I know my variable works fine but I can't seem to use a variable in place of the numerical.
If this doesn't make sense, think of the scrollbar in IE or notepad, you can only scroll as far as there is something, unlike in SED where if you hit the down arrow on the scrollbar you just keep going down. I have up and down arrows just like IE (and all other windows programs) but I want the scrollbar to work properly too.
please advise me.

I once faced the same problem.
I think it's because vslider = x, y, len, bmap, min, max, var; is kind of an internal engine structure, where the compiler expects an initialization with numeric values before runtime.
The same pbl occurs when you try to do this with TEXT pos_x etc.
While for text the solution was simple (write a function and change these values after initialisation: mytxt.pos_x = 123;, for the slider it did not work for my purpose.
My workaround consisted in builing my own slider with a bitmap, that could be shifted up and down with the mouse. By knowing the actual y-position of your slider-bitmap, you are able to calculate the rest (let lines appear and disappear on top and bottom or vice versa. But it was a pain in the ass to programm all that alone.
