Maybe I wasn't too naughty after all then!

But how does Watford DFS store the catalogue with 62 entries, presumably
it needs twice as much space for it as an Acorn DFS disc?

Best wishes,

I don't know of any DFS that does not use the Acorn DFS catalogue
format. It's likely that those that don't already have a *FREE
command in ROM anyway.

But when directory=ASC"a" it will read the files it read when
directory=ASC"A"... except on some DFSs it doesn't!
