Well, this likely doesn't help. But on my Linux/Intel system, I created a text file which was 4.7 Gb (5,033,145,276 bytes). I used the jar command to create a .zip file which was 260Mb (272,331,844 bytes) in size. I am running the "IcedTea" version of Java on my Linux system, which is 1.6.0 . Unfortunately, I cannot test on z/OS as I just can't get that much storage. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
