It *should* work.

It's not normally necessary to use /FORCE. What happens when you omit it?

Also, it's not normally necessary to use CLOSE. FREE_LUN on its own
should close the file if necessary, before freeing the unit number. (But
using CLOSE shouldn't cause a problem.)

Have you made some more elementary mistake, like passing an incorrect
unit number? For example, the following would leave file1 opened:

openw, u, file1, /GET_LUN
openw, u, file2, /GET_LUN
...write some stuff
free_lun, u
free_lun, u

What happens when you try CLOSE, /ALL?
