5.9 Relocatable List File
The relocatable list file is an assembly source file that carries assembled results (offset addresses and
object codes) added to the first half of each line. It is delivered only when the start-up option (-l) is
specified.
Its file format is a text file, and the file name, <File name>.lst. (The <File name> is the same as that of the
input source file.)
The format of each line of the assembly list file is as follows:
Line No.: Address Code Source statement

Content of line No.
The source line number from top of the file will be delivered.
Content of address
In the case of an absolute section, an absolute address will be delivered in hexadecimal number.
In the case of a relocatable section, a relative address will be delivered in hexadecimal number from
top of the file.
Content of code
CODE section: The instruction (machine language) codes are delivered in hexadecimal numbers. One
address corresponds with one instruction. The assembler sets the operand (immediate
data) of the code that refers to unresolved address to 0. The immediate data will be
decided by the linker.
BSS section: Irrespective of the size of the secured area, 00 is always delivered here.
Only the address defined for a symbol (top address of the secured area) is delivered as
the address of the BSS section.
