i saw danshadow's forum thingny and noticed he didnt mask the passwords so i made this

code:
fcn getpass : string
    var pass := ""
    var charc : string (1)
    loop
        getch (charc)
        exit when ord (charc) = 10
        if ord (charc) = 8 and length (pass) not= 0 then
            locate (whatrow, whatcol - 1)
            put " " ..
            locate (whatrow, whatcol - 1)
            pass := pass (1 .. length (pass) - 1)
        elsif ord (charc) not= 8 then
            pass := pass + charc
            put "*" ..
        end if
    end loop
    put ""
    result pass
end getpass

put getpass

Why not use setscreen ("noecho") and avoid all that locate nonsense?

because the user needs feedback to know that the key was accepted, especially with a wonky kb. Oh in VB just set the passwordChar property to * in your edit box (I'm not kidding)

For the passwordChar all the * means is that when the user types replace it with a *. You don't actually set it in the code. You just change it in the properties box. You can use any character but * is the most common.

I know they need feedback. I'm saying, use noecho so that whatever they type doesn't show up, and whenever they press a key (except backspace and enter), put a * at the location. That's how I did the login for my game, the only difference is that I was using Font.Draw instead of put.
