Is it possible to construct calls to 'toolbx.sub' for routines
that are not listed in the various include files supplied with 
MacFortran? Specifically, I would like to be able to call Date2Secs
and Secs2Date.
   What is the relationship of the value of the parameter in the
include file to its trap word? In the old v1.0 file 'toolbx.inc'
the parameter was the ordinal position of the routine in the trap
word list. In the new version (2.2) it is some 4-byte thing; only the
first 1 1/2 bytes seem to have anything to do with the actual value
of the trap word (at first glance.)
   Has someone decoded this? Is it possible to access non-include-ed
ROM calls?
