Xbase project source code
This program tests the xdate routines
This program tests and demonstrates usage of the various xbDate methods
Several of the tests pass either StringDate or Chardate to the method
being tested - this is done to test the class methods. In actual usage,
this may not be necessary due to the instance of the class already
containing a date value.
