4.4 Comments
An assembly comment is initiated with a semicolon that is not part of a
string or character constant, for
example:
movlw 22 ;this value will ensure there is a good safety margin
If the assembly file is first processed by the C preprocessor, then the
file can also contain C or C++ style comments using the standard /* ... */
and //
syntax.
Avoid using assembly comments (;comment
) in preprocessor directives,
especially the #define
directive. Assembly comments are not removed by the
C preprocessor prior to macro substitution and so will appear in the substituted text,
possibly resulting in build errors. Always use C or C++ style comments in these
situations.
