Thats what comes of working with an older doc set, no details on 
IARGPTR.  It does indeed cause the fortran compiler to do something 
like a home operation and produces a data structure that has a 
longword argument counter, followed by quadwords pointing to the 
individual arguments.  It DOESN'T pack the addresses into longwords 
the way the Macro 32 compiler does, but it's close enough.  The 
function doesn't exist on my version of Fortran on my Vax systems, 
but its fakeable there.
