Please follow the previous messages; I pointed the fact that tabs could be
conceived  as object oriented system.

If a tab needs to create a process, it needs to keep the process variable
TABPROC somewhere. This 'somewhere does not belong to global env, but to a
tab-env.

The system will never see the variable  TABPROC.

The variable tabproc is evaluated only by the callbacks associated with the
events of the tab.

Only the callbacks of the tab need to evaluate that variable.

Frame local and buffer-local works on another env which is accessible to
Eval, so to global env. In object oriented, the envs are separated.

For me it is clear that we will never agree on a common solution . The
conclusion is that only 1 person will have to write the code for
console/gtk/athena/motif. I can write it, and need to read the manual of
motif and athena. I know GTK at beginning level.

I will not be abe to cope with this problem in the near future.
