- Pause -- wait for keypress
-
- Syntax Pause [prompt]
-
- Description Pause displays a prompt on the screen and then waits for a
- keypress. If the 'prompt' argument is not supplied on the command
- line, the utility will use a default string as the prompt.
-
- After displaying the prompt, the program loops until a key is
- pressed. If the keypress is a Command-., a status code of -1 is
- returned. Any other keypress returns a status code of 0.
-
- This utility is most useful for inserting a pause into shell
- command files (EXEC files) which require some action by the user
- prior to continuation of the script.
-
- Input None
-
- Output Pause writes the prompt string to diagnostic output. This is to
- ensure that the prompt string appears on the console device if
- standard output has been redirected.
-
- Diagnostics None
-
- Status The following status codes may be returned:
-
- 0 Any key besides Command-. has been pressed.
-
- -1 Command-. has been pressed, signifying that the user wishes to
- abort the script.
-
- Options A prompt string may be defined on the command line. This prompt
- string will be displayed instead of the default prompt string.
-
- Example: The following lines appear in a backup script:
-
- .
- .
- .
- Copy -c /Hard.Drive/APW/Source/= /Source.Backup
- Pause Please insert the /Object.Backup disk...
- Copy -c /Hard.Drive/APW/Objects/= /Object.Backup
