.hl 2 CNDTAD - Convert Numeric Date To Ascii Date
 
The CNDTAD routine will convert a numeric (3 integer) date into a DEC
format ascii date (DD-MMM-YY).  It can also be used to validate a
numeric date,
as the conversion will fail for invalid numeric dates.  The date string
A_DATE will be returned as zero length if an invalid integer date
is supplied.
 
The date string A_DATE must be a valid type0 or type1 string.  The date
will be "assigned" to the A_DATE string, so any previous contents of
the string will be overwritten.
