*Any* display operation. It happens with *HELP DFS as well!

If you're into reprogramming your DFS EPROM, then with DFS 1.2x
changing the byte at &B994 from &AA to &60 disables the code that
changes the output stream with *FX3.

In fact, as programming an EPROM involves changing '1' bits to '0'
bits, you /could/ reprogram a DFS EPROM without erasing it by
changing location &B996 from &03 to &01, causing it to issue FX1
calls (set User Result Byte) instead of FX3 calls.
