ASM
If the assembler tries to assemble at an address that is not in RAM or EEPROM, an invalid
address message "rom-xxxx" is displayed on the terminal CRT (xxxx = invalid address).
Assembler/disassembler subcommands are as follows. If the assembler detects an error in the
new source line, the assembler will output an error message and then reopen the same address
location.

In the above example memory locations $0100-$0108 previously
contained $FF data which disassembles to STX $FFFF.

Assemble the current line and then disassemble the same address location.
Assemble the current line and then disassemble the previous sequential
address location.
Assemble the current line and then disassemble the next opcode address.
Assemble the current line. If there isn't a new line to assemble, then
disassemble the next sequential address location. Otherwise, disassemble
the next opcode address.
Exit the assembler mode of operation.

Assembler/Disassembler
Immediate mode addressing, requires #
before operand.
Direct mode addressing.
Index mode, if offset = 0 (,X) will not
be accepted.
Branch out of range message.
Branch offsets calculated automatically,
address required as branch operand.
