Panasonic MN1030 user manual DATA, PUBLIC,4

Chapter 3 Introduction to Operation

generate list files (program3.lst and program4.lst) respectively in the current directory (l option). Adding debug information (g option) enables symbols to be used during debugging.

Let's take a look at the list files that were created.

The contents of the list file program3.lst are as follows.

Note that the symbol table is not displayed.

There is a plus sign '+' before line numbers 9 and 10. This indicates that the object code does not have final values. This is because the two functions data_set and time_filler do not exist in this program, so the call addresses will not be resolved unless linked. That further means that this list file is not the final list file.

Line number 11 also has a plus sign. This indicator warns that the line contains a symbol that is not assigned a final value until linking.

Finally, notice that the list begins from location 000000. The start addresses of section format programs are specified with the linker. Here the assembler uses relative values beginning from 000000 as location counter values.
