Notice the "drive / user areas" have names and the prompt has a
time-stamp in it.

Do you see the file named LEE11H.COM?

A DOS version of this CP/M program is LEE11HD.EXE.

"Letter Extractor / Enhancer" is written in BASIC. It takes text files
and converts them into "handwritten" files. It uses many small graphic
files for the letters, numbers and special characters.

To exit the Z-System environment, type EXIT.

Here's a sample run of LEE11HD.EXE.


Usage : LEE [[I=input file] [O=output file] [P=prefix]] or
        LEE no command tail to be prompted

LEE, (Letter Extractor / Enhancer), Version 1.1H
LEE generates "handwritten" files from text files.

Done. File CLIFFH.HTM created.
