### Asynchronous

Asynchronous radio button in PM debugging mode dialog

Note: This section applies to OS/2 only.

When the debugger is operating in asynchronous mode and the program you are debugging is stopped, the debugger responds immediately to messages that have been sent to the program being debugged on this program's behalf. The debugger answers the messages with a simple default response, freeing up other processes to operate while the debugger has control. When you are running the debugger in asynchronous mode, other PM applications running in the system are not blocked when the program being debugged stops.

Caution: Do not operate the debugger in asynchronous mode if the PM application that you are debugging requires the appropriate response to its messages. For example, a dynamic data exchange (DDE) message would require the appropriate response.
