Thanks to Everyone who sent suggestions about the password entry.

From all of those suggestions, here's what I built for TP3.01 on an IBM.

{*****************}
Procedure GetPassWd;

Var  Tempwd:string[15];	
     oldtemp:string[15];

Begin   {GetPasswd}
  clrscr;
  write('Password (dots will echo): ');
  passwd:='';			
  tempwd:='';
  oldtemp:='';
  Repeat
   oldtemp:=tempwd;
   tempwd:=passwd;
   Read(kbd, ch);
   if (Ord(ch)<>13) and (Ord(ch)<>8) then
    Begin
      Passwd:=Passwd + ch;
      write('.');
    End;
   if (Ord(ch)=8) then    	{Backspace}
    Begin
     write(ch);
     passwd:=oldtemp;		{Put passwd minus one character} 
    End;
  Until (Ord(ch)=13);  		{Until Enter is Pressed}
End;				{GetPassWd}

{****************}

The tempwd and oldtemp Vars allow the use of the backspace to correct the
password if mistyped.  It's not the cleanest code I've ever seen, BUT it get
the job done.  Thanks for the Help!
