        Single line DIS/ASSEMBLER Command

    The Single line Assembler / Disassembler is used to view
memory contents as instruction codes and/or to enter new
instruction codes into memory.

    When invoked, this command asks for a starting address. You
must reply with a valid hex-decimal memory address. Upon receiving
a valid address, EVSbug332 reads the M68332 memory and disassembles
the instruction found at that address. The disassembled instruction
is then displayed. At this point you may, assemble a new
instruction, move to the next instruction, begin disassembling at
a new address, or exit the command.

    If you wish to assemble a new instruction into m68332 memory,
enter the instruction mnemonic followed by all the required
operands. No imbedded white spaces are allowed as they are used
field delimiters. No label references are allowed and all numeric
data must be valid hex-decimal preceded by a dollar sign ($). A
correctly entered instruction  is assembled into m68332 memory (if
it is alterable) and the memory location following the instruction
is read and disassembled, completing the sequence. An incorrectly
entered instruction displays an error message and remains at the
currently open memory location, allowing you to re-enter the
instruction.

    If you wish to proceed to the next instruction without adding
a new instruction, simple press the <Enter> key. The next
instruction will be read from the M68332 memory and disassembled.

    If you wish to exit the command or begin disassembling at a
new address location, enter a period (.) in place of a new
instruction. At this point you are asked if you wish to continue.
Entry of a "C" restarts the process by asking for a new address
location at which to assemble / disassemble M68332 instructions.
Entry of any other character terminated the command.
