All ZShell programs
will work on Usgard. But, OS-85, Rigel, and PhatOS shell programs
won't work with the Usgard shell. At the bottom of the page is the
libraries section. There are 19 libraries, and some are needed to
run certain files. The first library is #1 and the last is #19.
Some programs will have numbers in parentheses after them that will tell
you what libraries they need to run.
