SNAP programs for Panasonic RL H-1400

[Mike Davis]

Does anyone have any information on how SNAP programs are written 
on a PC and downloaded to a Panasonic H1400?

Are they just text files?  Does it require a development system?  

Anyone know where syntax info is available, if BASIC-like or text files?  I 
can't find anything on the internet about SNAP applications for the 
Panasonic H1400, related to actually writing programs in SNAP for the 1400.

Thanks,
