Kris,

You recently posted a listing in notes:

|     A few weeks ago, someone posted a 5 byte program that could be entered
| into memory with the debugger, and then be saved as a runnable program.
| Could someone please send me a copy?

The program is quite simple.  The assembler instruction is

		JMP  FFFF:0000

Which simply branches to the RESET vector in ROM.  The hex bytes which
make up this instruction are

	EA 00 00 FF FF

If you want the code to be short (5 bytes), make it a .COM files, not
an .EXE file.  Good luck.
