(It is not necessary to enter the extension when giving file name.)

Examination of both PT columns and alphabet grid should indicate more
PT letters. These are added by entering the PT col. number or the grid
row number, (both are the same) and then CT letter and PT letter.
Entering 99 instead of a col. will cross reference the known letters.
This may be slow, especially when there are a lot of letters in!
