It *does* interpolate the string register value, but only at *troff* runtime. (Well, actually it's not the ".so" request that does the interpolation but rather the general read-and-process-an-input-line mechanism of troff that does this.) > 1. to modify only some string registers at the top of a document > to control the "sourcing" without the need to look up the `.so' > requests (essentially the same reason one prefers to define some > constants at the top of a programm instead of hardcoding numbers > all over the place). It appears that what you're attempting is some "configuration" mechanism just to make life easier, and that you're not dependent on it actually being troff that does the interpolation (i.e., you're not "computing" the name from information that only troff, and no other program, would have). My suggestion would be to simply use a general-purpose preprocessor such as m4 (or perhaps even cpp) as the first stage in the processing pipeline. _______________________________________________ Groff mailing list Groff@gnu.org http://lists.gnu.org/mailman/listinfo/groff
