I prefer comments also.

Yes, at a VMS-specific call site ($QIOW, LIB$whatever, etc.), then yes, use every extension you need (%LOC, etc.).  But stick to the standard elsewhere to help isolate the platform code.  That is where macros, jacket routines, even classes in object-oriented languages will help.
