Decimal BASIC, an ISO standard BASIC for Windows now has a Linux version (so far only
in Japanese)
Since the keywords and reserved words are all in English, you should be able to run
it even if you don't read Japanese (I don't) This BASIC is updated frequently and
now comprises almost all the ISO/ANSI Full BASIC standard. Check it out. If you
use True BASIC, you'll be at home right away. If not, try it!
