above $8000. If this location is set to $80 TEDMON displays the RAM
under BASIC and the KERNAL. This is often convenient for machine
language program development. Note that location $7F8 does not
affect the GO command. The GO command starts execution in the
current memory map (ROM on or RAM on) regardless of the setting
of location $7F8.
Enter TEDMON by typing:
MONITOR
TEDMON responds by displaying the 6502 registers and flashing the
cursor. The cursor is your prompt that lets you know that TEDMON is
waiting for your commands
Command command: a
Descriptions PURPOSE: Enter a line of assembly code.
SYNTAX: A <addres$> <opcode mnemonio <operand>
<addres$> A hexadecimal number indicating the location in memory
to place the opcode.
<opcode mnemonio A standard MOS technology assembly lan
guage mnemonic, e.g. LDA, STX, ROR, etc.
<operand> The operand, when required, can be of any of the legal
addressing modes. (For zero-page modes a 2 digit hex number is re
quired whose value is less than $100. For non-zero page addresses
4 digit hex numbers are required.)
A return is used to indicate the end of the assembly line. If there
are any errors on me ire. a question mark Is displayed to indicate an
error, and the cursor moves to the next line. The screen editor can be
used to correct any errors on the line.
After a line of code is successfully assembled, the assembler prints a
prompt containing the next legal memory location for an instruction, so
A and the line number do not have to be typed more than once when
typing assembly language programs into the Plus/4.
