Procedures in the default version of the IDL Astro Library are meant to work
for versions V5.6 or later.   This directory contains updates of procedures
that take advantage of new features in IDL V6.0.    These procedures will *not*
work in earlier versions of IDL.     Currently, these procedures must be
considered "beta" versions, since they have not been extremely well tested.
 
IDL_VALIDNAME() - can be removed since intrinsic function was introduced in V6.0 
 
MINMAX() - Uses the subscript_max keyword to MIN()
