The UNIFORTH Sampler is the first public domain floating-point
FORTH available for the Z80 CP/M and MS/PC-DOS (including non-clones)
computers.
This is a solid, full-featured FORTH that is a subset of the
vendor's more extensive Professional Series. Unlike the
FIG-FORTHs that are normally seen on bulletin boards, the Sampler
complies with the latest FORTH-83 Standard. It has many advanced
features, such as:
* Full software single-precision (IEEE format) floating point,
including all trig, log, square root, etc. functions. Compact
and fast, the floating point package is fully integrated into
the Sampler and can be used as easily as integer arithmetic.
* DOS support. Each version uses the underlying DOS file system
for containment of FORTH source code and data. You may open, close,
create, delete, read and write from any file type, including
ASCII text files. Clock and printer support are also provided.
* A versatile video editor. It can be easily configured to support
the IBM PC, ADM-3, TV-912, H-19 and VT-100 terminals. Other
terminal types just require the definition of a half-dozen words.
* Full assembler. Every opcode that is accepted by the processor
is included.
* Documentation. Over 60 pages of machine-readable text is
provided on the disk. You may optionally purchase a full, 500+
page documentation set.
* Fast. Dictionaries are hashed for maximum compile speed.
Most of the system is written in machine language.
All of the features listed above are missing from public
domain FORTHs currently available.
The UNIFORTH Sampler is distributed under the "freeware" concept.
We ask for a $25 donation if you find the program useful. You
are free to distribute the system to other users and bulletin
boards, or use it as the basis for your application programs.
New versions will be released shortly for the Commodore 64,
Apple II (ProDos), and Macintosh. We also have a 16-page
catalog free for the asking.
