Subject: How do I call GDB?

  Please how ca I call the Gnu debugger GDB? According to the help in
C:\DJGPP\DOCS\GDB\, to run the program ZXCVBNM.EXE with the Gnu C debugger,
type GDB ZXCVBNM.EXE . But that fails `no such file or command'. Search
through my \DJGPP\..... tree reveals no file GDB.EXE (or GDB.BAT or whatever),
but there are these two files:-
    630784 1994 Jul 27  2.06.44 C:\DJGPP\BIN\GDB
    630784 1994 Jul 27  2.06.44 C:\DJGPP\BIN\GDB-DPMI
  So, I tried typing    go32 \djgpp\bin\gdb
  and this happened:-
EXCEPTION OCCURRED!  Information dumped to core file:
    "t$gccdbg"
  and the file T$GCCDBG is:-
