I don't know how this program works, but if I wanted to make a
calculator I would like to have one that reads what I write until I
press the <RETURN> key like:

   2 + 3 * ( 6 / 7) - log(5)<RETURN>

To get this I would read what the user types by a Get_Line statement.
Get_Line will wait until you hit return. Now you use Get on this string
to find all the operands etc. You can thus keep the old code (you can
just add . to the string the user typed).
