    i think the original question was about the exec support functions
(CreatePort, DeletePort, etc), which are C routines, and not library
members - there aren't any LVO's for them.  i haven't tried to use them
from assembler, so i'm just guessing: use XREF's, prepend '_' to the name,
push the args in right-to-left order, JSR to the function, then "pop" the
args back off the stack.
