Hi David

It's the 2nd part of the statement I was pointing out, the "={...}"
bit. He's trying to initialize a pointer with structure data,
without dereferencing the pointer.
{
Btw, I'm not strong on multiple equal statements like that. I
know that
int i=1, j=2, k=3;
i=j=k;
makes i,j,k all equal to 3. But I'm not certain exactly what
happens in what order. Could get very confusing if more
complicated.

yes, but if you stuff up somewhere, the compiler may sometimes
give an error msg about a class violation or similar, rather than a
more accurate msg that you'd get outside the class.
Probably the answer I should have given Griffon is something like
// In the class definition, set up y as a data member
unit *y;
// Somewhere else, point y at a new unit and initialize it
y = new unit ['c',1];
// and don't forget to delete(y) before the class disappears...
Hope he's still listening.
Cheers
