c     Purpose:

44
c           Any netCDF file written to must be closed with the call
45

46
c        as in the argumentlist below.

c     Purpose:
741

742
c        a variable from an IVE-NetCDF file for use with the IVE plotting
743
c        package. Prior to calling this routine, the file must be opened
744
c        with a call to opncdf.

757
c                              origin of each variable. 
758
c                              Is dimensioned at least Min(3,ndim). 
759
c        varmax  real  output  the extend of each variable in physical
760
c                              space.
761

765
c                              routine.
766
c                              error = 0   no errors detected.
767
c                              error = 1   the variable is not on the file.
