That does not handle BackSpace (or any other "special key") AFAICS?
Reminds me of one of my program I wrote > 2 years ago.
You could have backspace and escape in your password ;-)

I later implemented an inputfield (using crt unit and reading
key-input using BIOS routines) that behaved just like an edit control,
so it would correctly handle left, right, delete, backspace etc.

Ahh, the good old days of Turbo Pascal.
Sorry, getting a bit sentimental.
