Sample Code
The following is a sample of CL programming. The program interactively converts dates from julian to mdy and vice versa. Results are displayed on line 24 of the terminal. It accepts two parameters. The &IN parameter which is the date string to be converted. If a julian string it should be in the format yynnn where yy is the year number and nnn is the day number of the year. If a MDY string it must be in the format mmddyy. The second parameter is &TYP which is the type of date to be converted to. It must be 'J' (julian) or 'M' (mdy). For example: the command CALL PGM(ICVTDATC) PARM('04180' 'M') will convert the julian date 04180 to 062804 (June 28, 2004).
