munpack is a fairly simple C program that does what you want (eats a MIME-formatted input file with multiple MIME elements) and writes the individual elements to files. You'll need to tweak the filename handling (or use it in a BFS environment), but it should compile cleanly on CMS. There are also Perl implementations of similar tools, which will run with Neale's port of Perl5 for OpenVM. -- db
