I looked at ProIV's documentation regarding creating memory files (topic ID 720293) and it has left me more confused than enlightened.
I took the simple approach of changing the file type of one of our existing "working files" and regenning all functions that reference it. It seems to have made no difference at all in execution speed of the report I was testing. The documentation also mentions adding an entry to pro4v7.ini which I did but it still makes no difference.
Help!
