Free_Lun both closes and frees up a logical unit number that has been
opened with Get_Lun (i.e., one in the range 100-128). There is no need
to use an additional Close in this case. Close should be used if you
have chosen a logical unit number from the range 1-99 (i.e, OpenR, 5,
...). Then, using a Close both closes the file and frees it. There is no
need to use Free_Lun in this case.

Cheers,

David
