Hi Francisco,
I've just printed the mary's manual and took a more thorough look at your
compiler. Let me ask you a few questions:
1) You wrote:
mary is part of the Glazz project, whose original aim was world
domination, later changed to the creation of a native code Forth system with
multiple targets.
Does it mean that you are considering the 8051 support?
There is no good GPL'd Forth for those microcontrollers...
2) I'd like to add the 16F84 support. It seems to me, that it should be enough
to change the MAXPICRAM0 definition from 2F to 4F in the 16c84-data.fs file.
Am I right?
3) mary is GPL'd, so what license applies to the code compiled with it?
If I use the code generated with mary in a commercial application, am I
obliged to provide the end user with the sources of my code?
Could you please state it explicitly in your documentation?
4) How could I implement the interrupt service routine in mary?
5) I'm sorry, but by mistake I've Cc'ed the first reply for your message
to the ####@####.#### instead of gnupic list - so in result
I've forwarded your message to that list :-(. However I hope you have
no objections to announcing of mary there...
Finally: you've done a wonderful work!
