These commands are available in Watford's DFS, specifically 
http://www.nvg.ntnu.no/bbc/rom/Watford/fs/DFS-1.44.rom,
which I always recommend to users of BeebEm.

Quite a few games in the archive are originally tape games and have
(once upon a time) been patched to rely on these commands for correct
loading and execution.

Also, a lot of disk images are available in Watford DFS format, meaning
that they might contain more than the standard 31 files on Acorn DFS
disks.
