Thank you Russ. I'd explored Lynton's manual as well, and was confused when
the close() function was not mentioned.
To finish up with my question, if I can not manually close a file, if I
open a NEW file with the same handle 'ncfile' (imagine the small code
snippet that I included earlier being inside a loop ), will this deallocate
the memory used by the earlier instance? I'd like to open (and close)
several files in sequence and would like to minimize memory usage.
Thank you
Taylor
