I would reccommend anyone referencing any of those two macros in their rs-in or rs-out to discontinue doing so at least until which time I can throw in a bugfix to handle looping expansions. Currently the expansion routine in the preprocessor will reach a depth limit and then spit out an error which gets interpretted by the main routine as a bogus expansion. This will nullify that import. -- /*===================[ Jake Khuon <khuon@Merit.Net> ]======================+ | Systems Research Programmer, IE Group /| /|[~|)|~|~ N E T W O R K | | VOX: (313) 763-4907 FAX: (313) 747-3185 / |/ |[_|\| | Incorporated | +==[ Suite C2122, Bldg. 1 4251 Plymouth Rd.
