If you are opening the file with GET_LUN, either as
a keyword or as the procedure, there is no need to use
CLOSE. FREE_LUN will both close the logical unit number
and free it up to be used over again.

Help, /FILES will tell you which files you currently have
open and attached to a logical unit number.

Cheers,

David
