Dear Helmut,

❝ BTW, I don’t understand what the purpose of the carry variable in Byron’s code is.

As far as I see it: It serves for nothing because it is not used except in the class statement of Proc Mixed.
The class statement serves the purpose of declaring factors even if a variable is numeric. Nothing more.

The carry variable seems to me a left over from old times where carry-over was an issue.
