Functional description
The listoff and liston directives are used in pairs. Statements from the statement following the listoff
directive until the statement preceding the liston directive will not be output to the list file. These
directives are used when you do not want to output an already debugged program to the list file.
NOTE: The listoff and liston directives themselves are output.
Only output to the list file will be suppressed. Output of object code will not be suppressed at all.
Operand coding rules
These directives take no operands.
Usage example
Below is an example use of the listoff and liston directives. The mov 0x22,D0 is a statement that
should not be output to the list file.
_CODE section CODE, PUBLIC, 2
main mov 0x11, D0
listoff
mov 0x22, D0
liston
mov 0x33, D0
end
