The picture string passed in a CEEDAYS or CEESECS call did not contain enough information. For example, it is an error to use the picture string MM/DD (month and day only) in a call to CEEDAYS or CEESECS, because the year value is missing. The minimum information required to calculate a Lilian value is either (1) month, day and year, or (2) year and Julian day.
The output value is set to 0.
Verify that the picture string specified in a call to CEEDAYS or CEESECS specifies, as a minimum, the location in the input string of either (1) the year, month, and day, or (2) the year and Julian day.
