Examples: Using ILE Common Execution Environment APIs

These ILE COBOL and ILE RPG programs call the ILE Common Execution Environment (CEE) APIs for date conversions.

      * This sample ILE COBOL program demonstrates how to call the
      * Common Execution Environment (CEE) Date APIs.  The program
      * accepts two parameters.  The first is the date in character
      * form and the second the format of the date.  For instance
      * CALL CEEDATES ('10131955' 'MMDDYYYY') causes the program
      * to treat the date as October 13 1955).
      *
      * The program then displays on the console the numeric day of
      * the week for that date (Sunday = 1) and the named day of
      * week for that date.
