[ Type code = > ] Converts from YYMMDD format (for internal storage) to either MMDDYY or DDMMYY (depending on use of D, U or u codes) for display and input. Note that this conversion will take place on both input and output, so if you want to preload a date field (see opcode parameter), it should be supplied in YYMMDD format, and INFLD will also return the date in that format (no matter what the input/display format was.)
