Hi.

I agree that the FOPEN and FCLOSE for each action is an overhead but I've found that more reliable than worrying about the state of the file between runs. In addition the close makes it possible for multiple sessions to write to the same file with fewer clashes.

The loss of speed doesn't bother me too much because it wouldn't "normally" be running in production.

It's proved very usefull for me. I'm using it as we speak to debug some dataloads I'm doing.

Cheers
