Janeforth is a copy of Jonesforth containing my modifications and extensions. Jonesforth is a brilliant forth tutorial by By Richard W.M. Jones, It is available here: http://git.annexia.org/?p=jonesforth.git;a=summary I didn't want to maintain the high level of commentary as I added new features so I removed all the tutorial comments. If you are looking for a tutorial go read the original Jonesforth. If you are confused about what this code is doing, go read the original Jonesforth. The original Jonesforth files jonesforth.S and jonesforth.f are included here unmodified for reference. Modifications: - all words are lower cased - 'depth' returns the depth in cells instead of bytes - .s prints stack in same format as gforth, with depth and tos on the right - tick that behaves as expected in compile and interpret modes Renamed words: dsp@ -> sp@ dsp@ -> sp! tell -> type ' -> ['] [compile] -> postpone added: ' nil 2/ 2* lshift rshift [char] reveal recursive r@ rpick ?do loop unloop i j k
