Using VFP8, is there a way to tell if a table is in use if that table was opened with a different alias?

For example:
**************************
USE employee IN 0 ALIAS emp &&This is OK.

***However, later on in the application...
IF !USED("employee") &&This will return TRUE.
USE employee IN 0 &&This would result in a File In Use error.
ENDIF
SELECT employee &&This would also error.
**************************

I know this isn't the best practice but how could I tell if employee is already in use in the current data session?

Thanks,

Jerry
