-----------------------------------

simple use Font.Draw to display what the user is typing

something like

var x, y : int := 100
var fontId : int := Font.New ("Arial:12")
var ch : string (1)

loop
    getch (ch)
    Font.Draw (ch, x, y, fontId, black)
    x += 10
end loop

-----------------------------------

you might wanna replace the
x+= 10 with x += Font.Width (ch, fontId)

Try this :)

-----------------------------------

var x, y : int := 100
var fontId : int := Font.New ("Arial:12")
var ch : string (1)
var word : string := ""

loop
    getch (ch)
    exit when ord (ch) = 10
    Font.Draw (ch, x, y, fontId, black)
    x += Font.Width (ch, fontId)
    word += ch
end loop

The Variable it gets stored in is word, this also outputs it to the screen.

Enter ends the loop and stops adding to the variable.

-----------------------------------

you are adding something together or adding something to a string. in an integer it will add the value and with a string it will add on a character. so
in x = 3
x+=2 will = 5
means the same thing as
x:=x+5

just a shortcut..
