Tiny BASIC Design Notes
RE: Ever wonder how BASIC works - ChickenMan - 24-12-2023
Thanks for that, for those that are not aware of Microbee Basic origin -
MICROWORLD LEVEL II BASIC is based on a BASIC interpreter
written by East Texas Computers. It was developed by John Arnold
and Dick Whipple who, incidentally, were the originators of the
first TINY BASIC. The "BASIC ETC" original was first totally
overhauled and rewritten extensively for the DGZ80 system by
Ron Harris and Matthew Starr.
An advert in the Computerworld 12 Feb 1979 had a bit more info -
Business Users Get Basic Tools
RICHARDSON, Texas — Business users can now take advantage of a source listing of Disk Basic Etc,
a Basic language interpreter, as well as Basic source listings and language and user manuals from
Binary Systems Corp.
The source listings for Disk Basic Etc are designed for Z80- and 8080-based systems and include a
48-page language manual and a 50-page instruction manual for modifying or adding routines.
Together with the manuals, the 6,000-line source listing allows users to equip their systems with a
Basic interpreter that can include user-defined command and I/O routines. As many as five custom
commands can be added without reassembling the pro gram, the firm said.
The interpreter features 60 standard commands and statements. The program generates 32 error
message codes and features editing capability. Direct memory and I/O addressing is standard.
