COMPUTEJULIANDAYNO Procedure
year input
INT:value
is the Gregorian year (for example, 1984, 1985, ... ). The range for
year is
restricted from 1 through 10000.
month input
INT:value
is the Gregorian month (1-12).
day input
INT:value
is the Gregorian day of the month (1-31).
error-mask output
INT:ref:1
is a bit array in which the first three bits correspond (bit by bit) to
year, month, and
day, as follows:
<0> year
<1> month
<2> day
If any one of these bits contains a 1, there is an error. If more than one bit is set,
then the combination of elements is bad; which element is actually in error is
unknown. For example, 01100000 00000000 is returned for April 31, in which case
it is unknown whether April is in error or 31.
