I looked up LOGFONT. No, I never anticipated that the api would
include such craziness.

Yes, "s" aka "string" is a pseudonym for char*. Every use I've ever
seen for char*s in structs have been simply a pointer member, not
actually chucking the string into what then becomes a variable-length
struct.
I'll try to think of a clever way of allowing such a thing, probably
by adding yet another modifier for "s".
In the meantime: how about making the last item a byteblock?
byteblocks can contain whatever you want. Be sure to include the
final \0.
I'd also though of array of chars and for/endfor to fill the
individual chars.
I'll have a go over the weekend with byteblock: want to post me the
script you're using that requires LOGFONT?

Error, will fix.

Two pointers of length 4 each, sounds okay.
