Yet there are a lot of installations running OpenVMS (Alpha and/or VAX variants) via virtual machines, because it is easier to certify that the VM emulation is producing identical binaries as the original hardware, than it is to certify the software that would be built by porting from the VMS build-tools to native (cross-) development {the case I have experience with is an emulated VAX/VMS running a cross-compiler for 68040}. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
