To code a wild carriage return in Xy3, you need to embed a _3-byte_
Ascii-10. (Func WC was broken, as I recall.) Hold down Ctrl+Shift
(or whatever combination of shifting keys accesses funcs R0, R1 ...
R9), press 1, 0, then release. The resulting character will display
and print (in XyWrite) as a normal Ascii-10, but actually will
consist of 3 bytes (Ascii-255 + "0A"). (The 3-byte construction can
be verified by SAving the character to a file and TYPEing the file
at the DOS command prompt. Not coincidentally, 0A is the
hexadecimal equivalent of 10 decimal.)

So, the code to search for a carriage return+line feed in Xy3 would
be:

 BC se [255+48+65]XC

where "[255+48+65]" represents the 3-byte Ascii-10 described above.

You can map a 3-byte Ascii-10 to a key with the following keyboard
file code (the character following the first comma isn't a space;
it's a 3-byte Ascii-255, produced by holding down Ctrl-Shift and
pressing 2,5,5):

nn=NO, ,0,A

nn=R1,R0 also works.
