Hi,

I am always desperately seeked for a bytecode-interpreted system. Unless I
did hear about XPL0 the only alternative would for me the CFLEA from
Mr. Dunfield (www.dunfield.com). However, I never did manage to decide
myself to buy that thing.

I am glad to hear now there would be a bytecode interpreter for XPL0 also
for PIC, not only for SX. My question is: where?

I would be very grateful as my projects would require a PIC larger than 8k
EEPROM (do you hear, Microchip?), but at this moment the 18Cxxx series
should be ignored by me (17Cxxx also) as there is no severe development
environment for DOS available.

Regards,
Imre

PS: I have looked at XPL0 already, and I am also fascinated of it.
