Stopping PV-WAVE
The most direct way to stop PV‑WAVE is to type EXIT or QUIT at the WAVE> prompt. You can also interrupt the current PV‑WAVE command and then resume with the .CON command, as explained in this section.
Exiting PV-WAVE
Entering an EXIT or QUIT command at the WAVE> prompt causes PV‑WAVE to exit unconditionally, and you are returned to the operating system prompt. The same thing happens if you enter <Control>-D or <Control>-Break; for more details, refer to "Control Characters that Interrupt or Stop PV-WAVE".
 
note
When you exit unconditionally, variable assignments are lost and any customizations made to PV‑WAVE, such as changing the font used in the windows, are lost unless you have explicitly saved them yourself by saving the session. However, data that is buffered for open output files is flushed to these files before exiting is complete.
Interrupting the Current PV‑WAVE Command
If you are running PV‑WAVE in Console mode, <Control>-C is the interrupt character. Typing the interrupt character generates a PV‑WAVE keyboard interrupt. When you enter the interrupt character at the WAVE> prompt, the following message is displayed:
% Interrupt encountered.
When the interpreter regains control (there may be a noticeable delay), you are returned to the WAVE> prompt. After interrupting PV‑WAVE, you can continue with the .CON command. For more details about using executive commands such as .CON to control programs, see the PV‑WAVE Reference.
Control Characters that Interrupt or Stop PV-WAVE
This section describes individual characters that can be entered in conjunction with the <Control> key to interrupt or stop PV‑WAVE. These characters are summarized in Control Characters.
 
Table 3-3: Control Characters
Character
Action
<Control>-C
Keyboard interrupt; enter .CON to continue.
<Control>-D
Signifies EOF; causes PV‑WAVE to exit.
<Control>-Break
Abort.
 
note
Control characters listed in the previous table are only recognized in the Console window. Control characters are not recognized in any auxiliary windows, such as graphics windows. (Exception: <Control>-C is a standard Windows accelerator, so it is recognized in any window where a Copy to Clipboard operation is meaningful.)
