To build RSAREF, copy the makefile for your operating system from the 'install' subdirectory to the 'test' subdirectory. Then run your operating system's 'make' program from the 'test' subdirectory. The makefile will compile the RSAREF source code and build the demonstration program. Makefiles are found in subdirectories of the 'install' subdirectory: dos Personal Computer running DOS, Microsoft C v6.00a mac Macintosh running System 7, MPW 3.2 unix NeXTStation, DECStation 3100, SPARCStation 1 vax MicroVAX II running VMS For example, suppose you are running DOS with Microsoft's NMAKE utility. From the 'test' directory you would run the commands: copy ..\install\dos\makefile nmake
