nstructions for use of DisAsm.100.
Load using HEXLDR.100 or other program that converts from Intel Hex format to a 
.CO program.  When loaded, the program should be 1217 bytes long.

Program prints          You enter
--------------          ---------
Start address:          A hex number between 0000 and FFFF
End address:            A hex number between 0000 and FFFF
Output to:              Nothing, or a valid M100 file/device name
                        (DISASM.DO, COM:98N1E, CAS:LIST, LCD:, LPT:, etc)

	Note the ;*** after JMP's, RET's, PCHL's and HLT's.  This can help to 
follow program flow.  You will also see that RST 1 and RST 7 are followed by 
DB's.  This makes it easier to follow Microsoft's program flow.  RST 1 compares 
the following byte with (HL).  If they don't match, you get a SN error.  RST 7 
gets the following byte, uses it as an offset to the table starting in FADA in 
high memory, and jumps there.
	You can stop execution of the disassembler by holding SHIFT-BREAK for a 
few seconds.  You can also pause the screen display by tapping any key.  Press 
it again, and it continues.
	This is fairly fast, it produces about 750 bytes/second, not bad....
	If you get enthusiastic and document your disassembly, send me a 
message, maybe we can trade code.  I have most of the cold/warm start routines, 
file handling, and hardware interfaces.  I am interested in the BASIC variable 
handling stuff.  Good luck.

ps. The first column is the address of the current instruction, the next
column is the opcode, then the registers/parameters, then the hexadecimal
representation of the instruction, then an ASCII copy.  You can see that after
the first JMP 7D33, the word MENU is
printed.
