Howdy Sujata!

Your arguments for ncvgtc are incorrect. As you can see from the documentation
(http://www.unidata.ucar.edu/software/netcdf/guide_9.html#SEC65) there are
seven arguments for this function.

I suggest that you want something like:

integer start(1), count(1)

start(1) = 1
count(1) = 1
call ncvgtc(ncid, tcid, start, count, sttime, 19, rcode)

I confess that I have not tried this.

Have you considered moving from the v2 api to the v3 api? You might find it
helpful (but it makes no difference with respect to your current question.)

Please let me know if this doesn't help.

Thanks,

Ed
