Very nice - scarletdme in the browser is brilliant!

The two things I do to start playing in a new MV environment both worked exactly as I hoped they would:

    LIST VOC

And

    ED BP BLAH
    I
    PRINT "THIS IS A TEST"
    
    FIBR

The environment feels very normal and reasonable, as far as a multivalue system goes. The only differences I came across are minor, like compiled programs going in BP.OUT instead of BP.O or the debugger being called DEBUG instead of RAID.

I definitely need to set this up and seriously play with it! I periodically download a new copy of UniVerse PE to play with, but this is something I could actually do real work in.

Believe it or not, I actually like working in ED and/or AE.

At one point (back in the UniVerse job), I wrote my own shell. It was basically a REPL that passed whatever you typed to EXEC, except for one nifty trick. The trick was that there were two REPLs in the program - one which worked normally, the other executed within a BEGIN TRANSACTION/END TRANSACTION block and had commands to commit and rollback. Having two REPLs was a concession to get it to even compile because BASIC required that BEGIN TRANSACTION and END TRANSACTION form a block, you couldn't just arbitrarily call those commands. I didn't even bother building a history mechanism, it was literally just a REPL that could work within the context of a transaction. It was incredibly useful.
