When we upgraded to 4.0 UC something a year ago on our HP9000/S855HPUX system, I had similar problems. They seemed to be caused by variables with names whos lengths were a multiple of 4. I know it sounds strange, but that was the case. For a variety of reasons, the above among them, we went back to our 2.?? versions of Informix products for another year. This past August we upgraded to 4.1 UE of everything. 4.1 is much more stable than the early versions of 4.0 which seemed to have bugs everywhere. --Glen -- Glen Gordon | Internet: ggordon@agsm.ucla.edu Computing Services | Bitnet : ggordon@uclagsm.bitnet Anderson Graduate School of Management | AT&Tnet : (213) 206-6590 University of California, Los Angeles | Fax : (213) 206-2002
