Mmemonic() or Mnemonic at PC. If you want to
include a line range or starting point in your command, enter it into the entry buffer
before you choose the Mnemonic() command.
•
Using the command line, display memory in mnemonic format by entering:
display memory <lower> [thru <upper>] mnemonic
A highlighted bar shows the location of the current program counter address. This
allows you to view the program counter while stepping through user program
execution.
When you display memory mnemonic, the emulator disassembles the memory
locations beginning with the first address you specify. If this address is not the
starting address of an instruction, the display will be incorrect.
To offset the addresses in the memory mnemonic display, add the parameter
offset_by <expression> to the end of the display memory command line.
<expression> is an address expression that is subtracted from each address in the
memory display. If code gets relocated, and therefore makes symbolic information
obsolete, you can use the offset_by option to change the address information so
that it again agrees with the symbolic information. You can also use offset_by to
change listed addresses so that they match addresses in compiler or assembler
listings.
Whether source lines, assembly language instructions, or symbols are included in
the display depends on what you choose with the Settings
→
Source/Symbols
Modes or Settings
→
Display Modes pulldown menu items.
Use the set symbols on command to display symbol information for addresses in
the memory mnemonic display.
If symbols are loaded into the interface, the default is to display source only.
