rclerk @once

Is it clearly described anywhere exactly what order the various @once 
@menu @update etc happen?

All these years I have been working on the assumption that I could trust 
that no matter what else happens, @once absolutely always happens, and 
always happens first.

I use it to initialize variables and rand("-1")

Today I discover that isn't guaranteed after all.

I have a table (someone else wrote) that runs in rclerk, 
non-interactively in a cgi.

The table had both @menu and @update, and I just tried add an @once, and 
discover that the @once is not being executed.

The @menu contains a "lookup -" followed by pushkey "U"

The bulk of the table is actually all IN the @update

Is it just that @menu or @update or both come before @once?
