If ACT does not reply then you could cancel your own contract. Then still the number of clients would alter by 1. This is comp.lang.ada and 2 line responses giving seemingly bad advice lacking the needed argument, is not ideal.

I suppose that GNAT compiler doubles the size of its tables which could be just about optimal. It seems that more RAN chips may be appropriate if the CPU is slowed by attending to paging. There is this gnatmake option (which may not speed things up): -gnatTnnn : All compiler tables start at nnn times usual starting size (Possibly ASIS (Sigada) could aid in the rearranging of any large Ada 95 program. I had a look and I failed to find the message of Mr Brunot and Dewar when using the groups.google.com search engine. Craig Carey
