The only way to achieve this is to trap the error generated when a Table cannot be opened exclusively:

Prior to VFP8.0

LOCAL llInUse
ON ERROR llInUse = .T.

USE TableName EXCLUSIVE

IF llInUse
    *Error occurred, table in use
ENDIF

In VFP8.0, however, it's less messy:

LOCAL loException AS Exception

TRY
    USE TableName EXCLUSIVE
CATCH TO loException
    *Table in use
ENDDTRY
