This is a common misconception. DOS is -not- a single-task operating
system. It provides non-concurrent multi-tasking, and supports
concurrent multi-tasking, including having a context switcher. What it
lacks is a scheduler. The PRINT utility (and WINDOWS etc.) have to
manage the scheduling themselves. This is also what Quarterdeck's
product (can't remember the name right away) does - provide a
scheduler.

The corresponding command to ps in DOS is MEM/D (or MEM/DEBUG depending
on version) which will show all loaded tasks and drivers.
