Longtime software developer/architect using more languages and environments than I can even remember. Apollo DomainOS? Anybody remember that? PRIME?
Been using mostly Microsoft stuff for the last 10 years or so, extensive C# and MS-SQL experience, and a whole ton of Bourne (Again) Shell scripts to do just about anything you can think of.
My first major development package was in IPC using Mailboxes (think pipes) on VAX/VMS. Second major development package was a parser written for the same platform. Both of these were written in FORTRAN-77 (UGH!), but the latter was later converted to C, and even eventually to C#.
