I suspect (but haven't checked) that PrJobInit is a "Toolbox glue" routine
that is defined as an in-line function (i.e., a piece of assembler
that is inserted in your program) rather than as a normal addressable
routine.  I believe that this capability was added to Think C 4.0.  You
can check by looking at the source of <PrintTraps.h>.

More likely, it's something missing or unclear in the documentation.
