Well, I sent this off to MacDTS as a bug report, but got back a hack
fix for the problem and the standard disclaimer "We don't do code-
level support for non-Partner types." So here goes to the net:

I have found what appears to be a possible bug in the IUDatePString
routine in the International Utilities Package. I wished to get the
date in long format containing only the numeric day of the month and
the month, leaving out the year and the day of the week. So I made the
following calls (in C):

main ()
{
	Str255 tempString;
	DateTimeRec tempTimeRec = {1904, 1, 1, 0, 0, 0, 1};
	unsigned long tempSecs;
	Intl1Hndl intlRsrc;
	Byte tempByte;

	intlRsrc = (Intl1Hndl)IUGetIntl(1);
	tempByte = (**intlRsrc).suppressDay;
	(**intlRsrc).suppressDay = supWeek + supYear;
	Date2Secs(&tempTimeRec, &tempSecs);
	IUDatePString(tempSecs, longDate, &tempString, intlRsrc);
	(**intlRsrc).suppressDay = tempByte;
}

Unfortunately, tempString is "January 1," instead of just "January 1".
This also happens if I use the new Script Manager calls.  Now, the
response I got, from someone who signed "sk", was to check if there was
a comma in the last byte and chop it off if there is. Bad answer.
First, I know that in some country, the separater won't be a comma, but
some other character. And sure as shootin', if I go looking for
separaters in the last byte, some country is going to have that as part
of the way they format a month and date.

What I would like to know is how to tell when IUDatePString is doing
something silly. I would like to know the algorithm by which that last
separater is put it so that I can work back from the intl. resource and
figure out if I *really* should chop off the last byte. Can anybody out
help?

Thanks,
pr
