Re: flushing out buffer of output PS file, OLDPS vs PS

Yes, I would certainly recommend that Arindam uses the EPS type directly.
The flushing issue can be addressed via the 'delete' function regardless of
the output format. Any calls to 'system' from within NCL can be a bit time
consuming, especially when that functionality is already in NCL.
