Typically you circumvent this problem by iterating over the "last"
dimension.  For example, if your variables have the time dimension,
you would typically do this:

   spawn rm outputfile.nc  !<- delete the output file
   repeat/l=1:`v10,return=lend` ( save/append/flie=outputfile.nc  v10, . . . . )

saving one timestep at each iteration.

Use the "show grid" or "show data" command to see the dimensionalities
of your variables.
