The AVM throws an instance of the Progress.Lang.UserInterrupt class and raises the STOP condition
when the AVM detects that the user has pressed the STOP key (usually mapped to CTRL+C on
Unix/Linux or CTRL+Break in Windows).
You can therefore catch instances of Progress.Lang.UserInterrupt in a CATCH block to trap each
STOP condition raised when the user interrupts the AVM in this way.
You cannot inherit from this class.

Notes
- To enable older behavior and prevent the AVM from throwing Progress.Lang.UserInterrupt objects, specify the Catch STOP
(-catchStop) startup parameter with the value 0 (-catchStop 0).
- In character mode only (running Linux, Unix, or character mode in
Windows), when in the context of waiting for a record lock, pressing CTRL+C cancels
the wait and causes the AVM to raise the STOP condition
and throw a Progress.Lang.LockConflict object (instead of
throwing a Progress.Lang.UserInterrupt object as in
other AVM contexts). For more information, see Progress.Lang.LockConflict class.
- Like other class-based objects that are no longer referenced, the AVM
automatically deletes UserInterrupt objects using garbage
collection.
