- New Release
-
- 4th_86 is an MSDOS-EGA based FORTH with all the irritating
- fetishes beloved by "Forth purists" removed. It was written
- specifically to introduce the concepts of FORTH to Higher
- Diploma Polytechnic students, and the documentation is
- largely tutorial in nature. Despite being designed to make
- FORTH more palatable to newcomers, 4th_86 is a fully
- functional implementation. Many graphics demonstration COM
- files are included along with a great deal of MASM and 4th
- source code.
-
- File structures are standard MSDOS accessed via DOS handles.
- Source files are edited by shelling to your conventional
- MSDOS editor. 4th_86 does ** NOT ** in ANY way use the old
- fashioned "Forth screen files", and needs no inbuilt editor
- or customised printer utilities. 4th_86 is Direct Threaded,
- and runs as a COM file in 64K of memory.
-
- Both FORTH and ASSEMBLY source can be loaded. The Assembly
- routines CAN be written "in-line" but 4th_86 is designed to
- allow standard ASM format files to be assembled with MASM to
- a BIN file and then binary loaded. This - and the
- essentially modular concept of FORTH itself - encourages a
- structured approach.
-
- Extensive debugging; tracing; and disassembly features are an
- essential part of the design. Loaded code can be patched,
- and re-defined words can be "linked" to replace previously
- defined words. Both MASM and FORTH routines can be
- disassembled.
-
- Most DOS functions can be accessed directly from within
- 4th_86 although it is possible to shell out to DOS if
- required. Paths and subdirectories are implemented.
-
- As user routines are added, the extended system can be saved
- to disk at any time. Alternatively, IMAGE files of the user
- application can be saved and quickly re-loaded as an
- alternative to re-threading the original source. Turnkey [
- meta-compiled ] COM files can also be saved to disk.
-
- UCC 4th was originally marketed by United Controls
- Corporation, Alabama, in 1982, for 8-bit hardware. United
- Controls Corporation have kindly given permission for this
- MSDOS re-write and extension to be released to the Public
- Domain.
-
- Hardware Requirements: IBM compatible
- preferably EGA graphics and hard disk
-
