Notes
This command may be used as frequently as needed to specify data
or generate output in the desired length and/or force units. Mixing
of different unit systems (Imperial, Metric, SI etc.) is allowed.
This command may be anywhere a primary level command (e.g,
JOINT COORD, MEMBER INCIDENCE, etc.) can be. In addition,
it may also be wherever a first level load command may be.
Exceptions: The second level load commands (MEMBER LOAD,
JOINT LOAD and FLOOR LOAD), allow the UNIT command to
be entered on a separate line, not within a continuation or between
semi-colons.
