Guardian Procedure Calls Reference Manual

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:
Year<0>
Month<1>
Day<2>
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.
Returned Value
INT(32)
The Julian day number, or -1 if any input parameter is not within the valid range.
