Yeah. It was a 3+ bug. In 3+, Ascii-253 was the first character in a
hidden six-byte string that triggered the display of modes and formats. Quite by
coincidence, or by lousy design, Ascii-253 is the third character of func WC. So
WC could never survive a screen refresh; EDITOR always thought it should interpret
the 253 as the onset of some new display characteristic. So forget about WC;
luckily you don't need it anyway, since the concept of a Wild carriage return has
about as much meaning as a wild capital A.

Several methods of SEarching for carriage returns are detailed in CTRLCHAR.TXT.
Go to:

Then search the XyWWWeb page for "CTRL": that should point you at
CTRLCHAR.TXT. After you've DLed it, look for SEarch Methods #4 and #5. (The
various six-byte Ascii-253 display mode triggers are also tabled there, under
SEarch Method #3.)

Good luck.
