That's because the shell must be present for functions like system() to work,
since the system() function is intended for a controlling shell. One of the
few major deficiences of GS/OS is that there still isn't a memory resident
CLI that supports the basic O/S functions (locating and launching files).
Shell programs are relied on for this, and the O/S provides lots of neat
support for shells, but Orca doesn't use much of it.

To get to the point, though: you'll need the Prodos 16 reference OR the
GS/OS reference vol. 1 (preferably the latter since you ought to have it
anyway if you're serious about programming the GS). They explain the System
Loader toolset, which is used to load other programs. I'm sorry I don't have
any code examples for you, Jonah Stich might if you ask nicely.
