In the previous file, you either deleted the define line or made it into a comment, so you can use it to
once again select the true condition.

Line number 14 was assembled. Check for yourself that omitting -D DEBUG will assemble line
number 16 instead. This technique enables the programmer to freely choose assembly conditions with
command option specifications.
There is also an assembler option for suppressing the source code lines not selected during conditional
assembly. For further details, see Chapter 5 "Using the Assembler" and Chapter 6 "Using the Linker."
