OK sorry Kate, I should have given a little more information.
On our system (AIX v5.3) we recently upgraded to 11.1.2 of UV from v10.3, and we deal a lot with lists. Large lists with hundreds of thousands or even millions of lines (elements). These are just lists of keys to records in files. One in particular is a fixed length seven byte key (alphanumeric). However the largest file has 3.5 million records in it. This means that our lists can get to over 3 million lines ( this is about 40MB of a single file in a Unix directory). On version 10.3 when a basic program or the ED editor was used to read one of these lists (with anything over 2 million lines of keys in it) it would just core dump and not be able to read it. The same thing occurred whether one had the list in the &SAVEDLISTS& file or anywhere else. To get around this problem we wrote software to split these large lists. However that was cumbersome and not always worked to specification. With UV 11.1.2 (and because according to Rocket they did a lot of work to improve memory management) we thought we'd be better off, handling some of these large lists. However it seems we were wrong. A Basic routine cannot read a list that is over 4 million records in it. It just falls over and the process dies. The AE editor is a little more graceful with some information before it also dies trying to open any large list of keys. I know there are ways around this issue, but we expected a lot better performance from the new version. I dont have the exact error at the moment, because I am not at work, but I can add it here if requested. One can always try it themselves to see the error, because it happens every time. I am sure most companies do not work with such large lists, but even so, core dumping instead of a gracious exit is not good enough. This is the first thing we learned when we started out as programmers decades ago. regards jack Kate Stanton wrote: > > What limit? I do not understand.
