Actually .COM programs have a <64k limit on code.  Data can be
anything available.  They start off owning the whole memory arena,
thus TSR's have to release the portion they don't use.  Addressing
is not particularly easy, the scheme is designed for assembly use.

The key characteristics are:  Single segment load.  No separate
stack segment.  CS=DS=ES=SS on entry. Entry at 0100h.
