The DAY-OF-INTEGER function converts a date in the Gregorian calendar from integer date form to Julian date form (YYYYDDD).
The function type is integer.
The function result is a seven-digit integer.
If the DATEPROC compiler option is in effect, the returned value is an expanded date field with implicit DATE FORMAT YYYYXXX.
The INTDATE compiler option affects the starting date for the integer date functions. For details, see the Enterprise COBOL Programming Guide.
The returned value represents the Julian equivalent of the integer specified as argument-1. The returned value is an integer of the form YYYYDDD where YYYY represents a year in the Gregorian calendar and DDD represents the day of that year.
