No. I've looked at them but the one thing  that bothered me is that
after defining a class (aka structure) one is free to add variables a
will.

For example, after the above I can write:

	mydata.dummy="bad data"

but, since it's just as hard to access the 'dummy' I guess it's not a
big deal. Just used to C too much I guess.

Looks like a class is the way to go.

Yes. started a bit this PM. I think that what I'll do is write a
conversion in tcl and end up with a very-verbose datafile format. With
PentiumIIs who cares about a few extra cycles of overhead parsing a
file. I've just gotta get into the 21th century.
