/* iffpstrings.c

 *  centralized message routine for IFFP modules
 *  If you plan to add international language support to
 *  your iffparse application, all of the iffparse module
 *  strings are here and are accessed via the SI() macro in
 *  iffp/iff.h which calls GetString() 
 *
 *  There is some #ifdef'd out code here which will be useful if you
 *  decide to localize your application when locale.library is released.
 *
 *  37.9 4/92   - fixed IFFerr() error equivalence tests and null string
 *  37.10  7/92 - fixes to localization routine
 *  39.2   9/92 - modify for new CatComp, mroe consistent string ID names
