3.3 IDs enclosed in Back Quotes

IDs can be enclosed in back quotes (`) and thus they can contain characters not allowed in "normal" IDs. However, there is at least one case where IDs in back quotes won't be recognized: if the expansion operator (%) is located at position 0 in a line.

Example using back quotes:

Module 1:

    `functionname.with.dots` PROC C PUBLIC a1:dword

Module 2:

    `functionname.with.dots` PROTO C :dword
    .code
    INVOKE `functionname.with.dots`, 1

Since IDs in back quotes are not 100% compatible with "normal" IDs, it might be considered to use the ALIAS directive instead. Be aware that, since the alias handling is a linker task, it is necessary to define both names, the alias name and the target name, as public.
