Hi,
        You need SAS 6.12 for this.  Check the functions varnum, vartype in
the online help.  They can be used exactly for this.
 
        If you have an older version you can get the information from a
SQL select of "type" from dictionary.columns table...
 
        Regards,
                Bernard Tremblay
