If you want to monitor an expression as it changes throughout an entire module,
you don’t need to create individual procedure-level watches for each routine
contained in the module. Instead, you can set a single watch that applies to an
entire module.
To define a watch at the module level, use either the Add Watch dialog box
(to create a new watch) or the Edit Watch dialog box (to modify an existing watch).
Just as with a procedure-level watch, you still need to select the appropriate
module from the Module combo box.
As before, the next step is to select an item from the Procedure combo box’s
drop-down list. Instead of selecting a particular procedure name, however, select
the item that says (All Procedures).
(All Procedures) is the first item contained in the drop-down list. By selecting
(All Procedures), your watch is automatically activated for every procedure contained
in the currently selected module.

Figure 18.25 shows how to use the Edit Watch dialog box to change the local
watch you set in the preceding section into a module-level watch.
