var c : string (1)
getch (c)
put "you pressed : ", c

works for a single character. If you put getch() in a loop, you could get whole words

alright well i understand how the strings work but it doesnt seem to work with int

this is what ive tried:

var number : int (1)
getch number[/b]

it works for characters only.

if you want a digit, you getch() it as a character, and then strint() convert it to a digit

Ok im done with getch stuff.  now i have a new problem, i cant divide integers

take at look:

var bi, binary : int

put "Enter a number: "
get bi

binary := bi / 2

when i divide by 2, i get "assigned value wrong type" 2 is high-lighted

That's because binary is an integer.  But division using / returns a real number.  (Think: 13 / 2).  

Alternatives are to use div, as in
binary := bi div 2
Or use round, as in
binary := round (bi / 2)
