Updated and Reviewed August 2010
The RC switch enables the use of several compiler and source code enhancements without breaking backwards Runtime Compatibility with AMOS. To be effective, you must use with COMPIL.LIT / OCMPIL.LIT 1.0(117)+ (not COMPLP) and without any of the /X:# switches. The idea is to accommodate people who want to compile under A-Shell and use as many A-Shell features as possible, but still retain the option of copying the RUN files to AMOS for execution there. RC was added to A-Shell in Build 924 of 29 March 2005.
The features which /RC adds to COMPIL or OCMPIL can be divided into fully and partially supported categories, as shown below.
