You wouldn't ordinarily be able to enter that line on the command line as-is, e.g. IFdVDUd wouldn't tokenise the VDU. Maybe what's required is something to give an error if the 255 byte limit is exceeded.
Also, just noticed: this is a BASIC V program!
MODE doesn't seem to be tokenised properly, eg try just MODE 1 gives 'Syntax Error at Line 10"
TINY should work on a BBC with small modification but I can't get it working even with a correct MODE: http://survex.com/~olly/rheolism/dsm_rheolism/history.html

Found the proper BBC version lower down the page :) This does work if you retokenise line 0 manually (with MODE)

It doesn't work (gives 'Bad Program') with this: http://survex.com/~olly/rheolism/dsm_rheolism/

If you make it one byte shorter by removing the 3 from the end then it can be LISTed but I think that's a symptom of another problem somewhere as it doesn't work if you split it into multiple lines across the colons
