UPDIR v1.1

In Mar 90 Jake G Schwartz (Jake-S@cup.portal.com) posted an UP function
for built-in Menus.

I've converted UP into system-RPL and added support for library sub-menus.
To generate UP, put the listings of UP.S and UP.M in the appropriate files,
then invoke the following commandlines at the MS-DOS (urgh) prompt:
rplcomp up.s up.a
sasm -e -N up.a
sload -H up.m
[No need; UP is on the disk. -jkh-]

[Note: Brian Walsh found a bug in the menu list of the original UP program by
Jake Schwartz. It went UP from some UNITS menus into the STAT menu! The bug
is corrected in this version of UP. -jkh-]
