Turing:

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

it works for characters only.

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

code:

var stuff :char
put "please press a letter key"
stuff := getchar
put "you pressed the ",stuff," key"


Try that

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
code:
binary := bi div 2

Or use round, as in
code:
binary := round (bi / 2)
