Hi Bob, A 64bit file has a very large capacity. The 64 bit number is binary so every bit = 1 greater power of 2. Whereas 2,147,483,648 = 2^31 then 9,223,372,036,854,775,808 = 2^63. A very big number indeed. The reason it is 31 and 63 is that the leftmost bit generally signifies the sign of the number, eg: whether it is a positive or a negative number. If it is 1 then it is negative, 0 is positive so it generally doesn't get used when calculating the filepointers.
I'm not that familiar with HPUX, however I'd be checking out any filesystem limitations there maybe. Depending on the filesystem you are using, eg: UFS, XFS or JFS there could be limitations on the maximum filesystem size. Check with your support people but Universe shouldn't be giving you any problems. Admittedly we are running a version 10.0 system on Tru64 but we have files that are now in excess of 25Gb so it really shouldn't be that.

We have 64 bit files on a 64 bit file system, but one of these files grew to over 4gb and blew up with an Internal Data Error on a BASIC write. I thought that 64 bit files were supposed to be vv large... thanks in advance.... ************************************************************ HSBC Bank plc Registered Office: 8 Canada Square, London E14 5HQ Registered in England - Number 14259 Authorised and regulated by the Financial Services Authority Member of the HSBC Bank marketing group.
