There are many labels in a procedure, so you have to specify that you
are taling about the entry label.

You should also reflect this in the variable names, both here and in the
other modules.

Don't we already have a procedure for extracting proc_labels from labels?

Apart from those, it's fine, so commit it when you have addressed the above.
