Welcome to the Next Forth wiki!

HOW TO START

1. Download the latest .zip file from Project Download directory https://github.com/mattsteeldue/vforth-next/tree/master/download
2. Copy from .zip file to Next's SD card the whole "vForth" directory to C:/tools/vForth, and the dot command in C:/dot
3. Forth System is loaded and activated by the Basic program C:/tools/vForth/forth17_loader.bas or via dot command .vforth
4. Previous version should be activated using the corresponding loader.

HOW TO CONTINUE

The first start performs the definition AUTOEXEC which executes 11 LOAD

To quit to Basic, you can give BYE

To re-enter Forth with a WARM start, you have to give interactively RUN.

To re-enter Forth with a COLD start, you have to give interactively RUN 20 instead.

Dot command version hasn't a WARM start, but accepts file-name as parameter that will be executed instead of AUTOEXEC.

At Basic prompt try: .vforth c:/tools/vforth/demo/fedora.f

To learn Forth Language or for a good reference I suggest the book "Starting FORTH" - Leo Brodie (1981, Forth Inc.). PDF hopefully available here https://www.forth.com/wp-content/uploads/2018/01/Starting-FORTH.pdf : The first edition is old enough to stick on 16 bit integers numbers. In this perspective, almost all Forth source and examples described in Leo's book are available from Screen 800 upward.
