High-Level Screen Management Intrinsic Library (Hi-Li) Reference Manual

Common Parameters 

The globalpak and returnpak parameters are used by each of the intrinsics
that make up Hi-Li, except for the HP32424 intrinsic.  Because these
parameters are common to most of the intrinsics, a discussion of their
uses and their subparameters is given here.  Refer to this section when
you need information about how to use the globalpak and returnpak 
parameters.
