[Forth] Playing with PMG's in ES Forth (English Softwware Forth)

[JonnyBritish]

The manual at Atarimania is a low DPI scan but played around with a few samples showing how to manipulate PMG's etc. Also added a short video showing result. You can also use shapes per PMG to also do animation in a PMG. Here is the code for this sample

Anyone have a better scan of the ES Forth manual or more information - did you ever use it?

ESFORTH.zip

I have not seen a good copy of the documentation.

 

Sorry this is a bit off topic, but is there any reason you want to use ES forth?

 

Have a look at the forth section on Carsten's Wiki. He has a selection of more "Modern", and better documented, forth version for the 8bit.

 

X-forth and Volks Forth are good options
