Many moons ago, I spent my callow youth as a VMS geek and was fairly capable for a mechanical engineer. I got around the Command Language Definition (CLD) compiler (I can't remember the name of the compiler) and learned to appreciate it's flexibility and power. UNIX/linux, etc. has nothing (that I've seen) that even comes close. The reason I bring this up is that a friend of mine has written a spec for an ambitious command line interpreter that has a bit of the flavor of the VMS CLD's. This has led me to wonder if anyone has seen a port of anything like the VMS CLD language to UNIX/linux. I know that the syntax would have to be different because the VMS option "/" would interfere with the *nix directory syntax. Anyone have any suggestions? And yes, I do remember punch cards, keypunches, paper tape, disk drives as big as washing machines, etc. TIA, Bill
