fwiw, the Help:Debugger "Set WatchPoint" says it is (see below), but
attempts to do so on NT4 are rebuffed with a "not supported on this
configuration" error message.
----------------------------------------------------------------------------
----------
A watchpoint is a location or region of memory that the debugger guards.
When a new value is written to a particular area of memory, the debugger
suspends execution of the target program and notifies you with an alert.
Variables or memory locations on which a watchpoint has been set are
underlined in red in symbolics, variable, or memory windows.
WARNING There are some significant restrictions to set watchpoints in
memory. You cannot set a watchpoint on a stack-based local variable, or on a
variable being held in a register. In addition, in Mac OS you cannot set a
watchpoint in low memory or the system heap.
To set a watchpoint from the Data menu:
1. Select a variable from the Variable window.
The variable is highlighted.
For details on viewing variables, see View variables or View local
variables.
2. Choose Set Watchpoint from the Data menu.
A Watchpoints window appears. You will see a red line (dotted line in
Windows) under the selected variable in the Watchpoint Window indicating a
watchpoint has been set for this variable.
NOTE: You can customize the color of the marker indicating a set watchpoint
by choosing Display Settings from the list of preferences panel in the IDE
Preferences window.
To set a watchpoint using drag-and-drop:
1. Select a variable from the Variable window.
For details on viewing variables, see View variables or View local
variables.
2. Choose Watchpoint Window from the Window menu.
A Watchpoint window appears.
3. Drag the highlighted variable from the Variable Window to the Watchpoint
Window.
A red line (dotted line in Windows) appears under the selected variable in
the variable window indicating that a watchpoint has been set.
To set a watchpoint using Memory Window:
1. Choose View Memory from the Debug menu.
2. Select a range of bytes in the memory window.
3. Choose Set Watchpoint from the Debug menu.
A red line (dotted line in Windows) appears under the selected variable in
the Variable Window indicating that a watchpoint has been set.
