Robert,

The AUSED() function will probably do what you need. It creates a two-dimensional array storing the alias in the first column and workarea in the second. Use DBF() to get the table name of the alias.

The TABLELIST() function below will return an array consisting of the alias and full path table name of every table open in the current data session, or an empty array if no tables are open.
FUNCTION TABLELIST( aTableArray )

LOCAL lnI, lnCount

lnCount = AUSED( aTableArray )

IF lnCount > 0

    FOR lnI = 1 TO lnCount
        aTableArray[ lnI, 2 ] = DBF( aTableArray[ lnI, 1 ] )
    NEXT

ENDIF

RETURN lnCount
The function is called passing an array by reference. For example:
USE c:\VFP\data\myTable ALIAS myAlias
USE c:\VFP\data\myTable ALIAS myOtherAlias AGAIN

DIMENSION myArray(1)

*   Pass the array by reference with the "@" operator
IF TABLELIST( @myArray ) > 0

    ? myArray[ 1, 1 ]  -> "myAlias"
    ? myArray[ 1, 2 ]  -> "c:\VFP\data\myTable"
    ? myArray[ 2, 1 ]  -> "myOtherAlias"
    ? myArray[ 2, 2 ]  -> "c:\VFP\data\myTable"

ENDIF
