To compile HELP: 1. first, make sure you have compiled the "Cats" library for your system. Be sure to use the same memory model (this trips up a lot of people.) 2. Then, set the CATS macro in the makefile to the *path* of the CATDB.LIB library file (for example, use C:\SRC\CATS not C:\SRC\CATS\LIB\CATS.LIB) 3. Type: make That's it. Edit the NLS\HELP.EN file to add new English messages. Feel free to provide translations of HELP.EN into other languages. The new translated files should be named HELP.xx (where "xx" is the two-letter country abbreviation - for example, Germany would use HELP.DE and France would use HELP.FR)
