Most of the machines I am familiar with either have registers which can
be used for integer or floating point arguments.  Some of them have
an index type (shorter integer) but those can convert between short
integer and long..  These machines include VAX, PYRAMID, CDC 6x00
and descendents, CRAY, CYBER 205 and ETA 10, and even vector mode
on the IBM 3090.
