Likewise for the IBM Mainframe operating systems MVS,OS/390,z/OS - much of which is written in (I believe) PL/M - a dialect much like PL/1.
Many of our Operating Systems seem to have evolved out of the old DEC RSTS system. For example, CP/M had a PIP command. Later renamed to COPY in DOS. UNIX had a hierarchical file structure. DOS inherited this feature early on. When you've been around for a while, you start to see the same features converge.. UNIX had quotas, we got Quotas with Win XP Server (well earlier, when you include the third party ISVs - as an add on). IBM had Language Environment (LE) before .NET come along. It all sort of runs together over time - it seems. Mike Hines ----------------------------------- Michael S Hines [EMAIL PROTECTED]
