First tested and verified version.

First tested and verified version.

Removed function enc_start_c.  This code was merged
with the enc_comp function. Bit "a" in the comp
section of each command has been fixed.

This has been verified to work using the assembler
included with the book.

Add, MaxL, RectL, PongL should all work fine now.

Removed print of "Input buffer loaded".
Command can now be piped into a file and tested directly.

Function has_more_commands was re-written. Now supports
files that end with strange combinations of
non-printable characters.
