Many 16-bit architectures have variants where data and code models
within each program are individually selected to be 16-bit or 
more-than-16-bit.  Usually 16-bit programs are called "small", and
more-than-16-bit programs are called "large".  Programs where data
and code pointers have different sizes are typically called "compact"
and "medium".

Most 8086 compilers also supported a "huge" mode which was larger and
slower than "large" although I forget the details.  IIRC, the Mark
Williams compiler for the 8086 also supported a "tiny" mode which code
and data in the same 16-bit segment.

Beware that these names have radically different meanings on some
