Here you go...  here is some tested source code:


{Scott Mitchell...   1996}

program Password_Program;
uses crt;
const TAB=9;  BACKSPACE=8;  ENTER=13;
var password:string;

{--------------------------------------------------------------------------}

procedure ClearKeyboardBuffer;
begin
    MEM[$0040:$001A]:=MEM[$0040:$001C];     {Clears Keyboard Buffer!}
end;

{--------------------------------------------------------------------------}

function LChar(s:char):char;
{This is the opposite of the function UPCASE(char).  This simply turns
a character into a lowercase character.}
begin
    if (ord(s)>=65) and (ord(s)<=90) then
           s:=chr(ord(s)+32);
    lchar:=s;
end;

{--------------------------------------------------------------------------}

procedure GetInput(var s:string; filler:char; capital:boolean);
{This procedure gets input from the user, and saves the response as the
 string S.  Filler is the character you want to "mask" the actual typing.
If you don't want the entry masked, just enter a ' ' in the procedure
decleration.  Capital is a boolean value (TRUE/FALSE) which, if declared
TRUE, forces Capitalization.  What this means, is that if the user types
in his response, it capitalizes the first letter automatically and makes
the rest lowercase.}

   ch:char;
