The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
Then again, on some operations you may NOT want to use a mediator, unless
I don't understand the program stack well. For instance, pretend you're
using some silly application that insists on multi member files. And
since you are using multi member files you can't use referential or check
constraints. So you decide to duplicate that with a trigger. Now, your
trigger can chain out to the 'parent' file and say you can't add this row
to the 'child' file because the parent doesn't exist. And since your
trigger can be called from any file operation (ie your application,
UPDDTA, Excel, File transfer, etc.) the way to handle that might be to
send an escape message.
