An essential program for VMS users written by Steve Jennen. SWiM is a text mode multi-window terminal application that allows you to work in several simultaneous sessions, each one displayed in a fully movable and resizeable window.

When I first used it at school I couldn't believe what I was seeing: it turned a VT320 into an almost-graphical multitasking terminal! On the downside, as each DCL session gobbled its own screen quota time, you could run out of it pretty quickly.
