Gorilla.BAS - CP/M version

This is a Modula-2 (despite the name) implementation for CP/M of the classic "GORILLA.BAS" BASIC game included in MS-DOS 5.0.

Why Turbo Modula-2?

The choice was mainly due to a historic interest: this compiler (never distributed by Borland) was written by Martin Odersky (the inventor of Scala language) and had never been used by a critical mass of users. So it was both a challenging choice and a historic research.
