Installation considerations specific to the VMS operating system. You will of course need a VMS version of GZIP, and VMSTAR, just to unpack the kit. In lieu of 'make', you need either MMS or MMK. The former should be available from Hewlett-Packard, but the last time I priced it (quite a while back, before Compaq bought DEC and H-P bought Compaq) it was fairly pricey. MMK is free, and available from http://www.madgoat.com/mmk.html Since the package is pure Perl, you can also install by copying General.pm to the appropriate place in your @INC directories, creating directory Games and Sudoku if necessary and placing General.pm in the latter. The executable needs to be run through the following (or something equivalent) to be useful: $fn = 'sudokug' $fhi = FileHandle->new ("<$fn") or die <new (">$fn.com") or die <) {print $fho $_} This needs to be executed from the bin directory of the expanded kit. Place the resultant .com file in a directory that is in your DCL$PATH. Or, place it with the other Perl scripts, and make sure your DCL$PATH includes this directory.
