I am currently taking a course in comparative programming languages,
and part of my requirement for the course is an independent project
written in a language of my choosing that I am not familiar with.
The project I am currently considering is implementing a simple to
moderately complex language interpreter in a compiled language like C.

I remember that some years ago I read an article (I believe it might
have been in Creative Computing) about a language called ZGRASS.  This
was an interpretive language that offered a number of powerful
primitives for graphic manipulation, such as scaling, bit-image
transfers, etc.  I remember that it ran on the Bally Astrocade, a
long-since-defunct videogame system that expanded into a full computer
with a Z-80, 32K of memory, and a dedicated graphics processor.  I
also remember that as an interpreter, it offered a few unusual
features that a language like Basic doesn't offer (such as relative
instead of absolute branching).  I thought it might be interesting for
me to try to implement this language (or a language of my own design
influenced by ZGRASS) on the Amiga.

Would anybody happen to know anything about this language, and/or
point me to any references?  Please E-mail replies, since I do not
usually read these newsgroups.  Thank you in advance.
