This example illustrates how to convert an mmddyy date to a ccyyddd date and a 3-character weekday string, and how to convert a ccyyddd date to a ccyy/mm/dd date and 1-digit weekday string.

The input records might be as follows:

120409  1999014
051895  2003235
999999  0000000
013099  1992343

The output records would be as follows:

2009338 FRI 1999/01/14 5
2095138 WED 2003/08/23 7
9999999 999 0000/00/00 0
1999030 SAT 1992/12/08 3

The Y2PAST=1996 option sets the century window to 1996-2095. The century window is used to transform yy in the Y2W field to ccyy.

Note that date conversion is not performed for the special indicators (all 9s and all 0s); the special indicator is just used appropriately for the output date field.
