>>Is there an easy way of telling if a table (in a multiuser environment) is already opened in the current data session under an unknow alias (don't ask)? I could always scan though all open work areas and test the table name of the alias, but that seems like the long way of getting the answer.

>AUSED() returns the workareas and aliases of the files opened in the current data session or specified one. Simply use that in conjunction with DBF() to determine if a file is in use under a different alias (i.e.: IF lcfile = DBF(a_used[lni, 1])). AUSED() also will let you indicate the datasession number.


Thanx, I was trying to avoid AUSED(). The function I wrote takes between 1 and 2 seconds to return the alias of an open file or a fail code.
