A typical listing is shown in Fig. 3-70. The first column in the program portion of the listing gives the value of the location counter immediately before the corresponding statement is assembled.
The second column shows the machine code that the statement is assembled into.
the third column is simply the line number in the source code, and the remainder of each line is the source code just as it is presented to the assembler. If an error is found, an error identifying number and message are output on the line following the line containing the error.
