Subject: Gammasoft BASIC

This is a version of BASIC. The commands are a little different than most
versions of BASIC. You may want to look at the file "Gammasoft BASIC Book"
for information.

This file requires the Gammasoft Runtime Engine. If you don't have the
Gammasoft Runtime Engine, you can download it from this server or, if you
have MacOS Easy Open enabled, use the HyperCard Player instead.

When you decompress this file, be sure to put it in the same folder as the
Main Menu file. Also put an alias of the Gammasoft BASIC file in the `Data
folder. Make sure the alias doesn't have an " alias" suffix or a space
after it's name.
