RE: Misunderstanding mem allocation and require files

hello Philipp

Many thanks, that was indeed the problem, I have added that line and it reports a figure back down into the 90 kb region.

The annoying part was, I had sort of realised I needed to do that and had put this wrong line in

package.loaded.language = nil

instead of package.loaded.frenchBig = nil

Of course it made no difference, so I commented it out and didn't mention it in my mail.

Thanks once again

Regards Geoff
