I just upgraded a customer from MPE/iX 4.0 to 5.0 push, with the latest powerpatch. Everything seems to be fine with one rather large exception. This customer has been using and depending upon a fairly old version of EXPERT, which I believe is no longer supported by Cognos. Since the 5.0 update, Expert dies with a stack overflow. All the usual remedies have been tried, including run ...;maxdata=31232;nocb. To no avail. Presumeably, there should be some way to reduce the problem program's stack appetite. Can anyone suggest a solution? Thanks in advance. ----------------------------------------------------------------------------- Gilles Schipper Voice: 905/889-3000 GSA Inc.
