I have a physical file that contains a date field in it.  I want to create
a logical file over it that is keyed by just the year and month portion of
the date field.  The DDS manual tells me that I can't use SST on date
fields.  Anyone know a way I can create a field in a logical file that is
a portion of a date field?
