Probably. The function julday_to_gregdate() in the UDNITS library doesn't have a Fortran interface. You could use any another routine that converts Julian day-number to Gregorian date. Alternatively, you could modify the file "lib/utlib.c" in the UDUNITS package by adding FCALLSCSUB4(julday_to_gregdate,jultogreg,JULTOGREG, LONG,PINT,PINT,PINT) just after the definition of the julday_to_gregdate() function. At least I think the above is correct -- you should verify that it does the right think by executing the command "make utlib.i" in that subdirectory and then examining the JULTOGREG subroutine. The two functions -- julday_to_gregdate() and gregdate_to_julday() -- were never intended to be used outside the UDUNITS package. > thanks again, > jeremy Regards, Steve Emmerson
