Hi, Derek: Yes, I was slowly coming round to the idea of the third option. It does mean that if you want to change the deferredness of a field, you have to change the type, which is a substantial alteration. David:
Is there any reason not to just write all lazy fields of variable size in a deferred manner?
I completely hadn't though of this! You will loose a bit of time, for example reading fields which were previously not deferred will require a file seek, but the effort/thought/efficiency trade-off is good. I think I will go with this. Thanks Neil
