I had a bit of a problem getting nethack 2.3e running on my system.  I tracked
the problem down to the fact that nethack discards the TERMCAP environment
variable if it does not begin with a "/" or a "\".  (For my system, TERMCAP=
C:\MISC\TERMCAP.)  Here is a simple patch to make it accept all values of
TERMCAP:

at offset 5487Eh (346,238 dec) in NETHACK.EXE, change 74h to EBh.  This forces
it to accept any value of TERMCAP.  (You did save BPE.EXE from comp.binaries.
ibm.pc last week, didn't you?  If not, ...)
