- VAX: The VAX acronym is derived from Virtual Address eXtension.
- The VAX computer is designed to use memory addresses beyond
- the hardware's actual limits, enabling it to handle pro-
- grams that are too large to fit into physical memory. The
- VAX computer system is a member of the Digital Equipment
- Corporation (DEC) computer family. Currently the VAX
- series includes models spanning the desktop VAX station to
- mainframe class multi-CPU VAX processors. These vary from
- the superminis, like MicroVAX, to the older, moderate sized
- 11/7XX series, to the newer 6000 series. These computer
- systems commonly use an operating system known as VMS.
-
- VMS: The VMS acronym is for Virtual Memory System. The operands
- of VMS are very similar to other operating systems. Back
- in the days of stand-alone computer systems, DEC had the
- idea for streamlining the operation of their computers for
- business and engineering. It conceived VMS as a way of
- allowing the basic computer management to be done by a user
- familiar with any of the multiple systems it made.
-
- DCL: The DCL acronym is for Digital Command Language. It is the
- fundamental language of the VMS. Those of you who have an
- IBM system, you can think of a DCL program like a batch
- file. You can do a lot with it (much more than a PC-DOS or
- MS-DOS batch) but it work basically the same way. One
- difference is that when you want to execute anything as if
- you were typing it in at the command prompt, you first must
- put a "$" in front of the command in the DCL program. DCL
- programs are commonly called COM files as well. When you
- are not executing a COM or DCL program file, you are almost
- always typing things into the DCL processor.
