In order to facilitate easy screen dumps, the command SDP\_KEY will set
up a hotkey which when pressed together with <ALT> will cause the whole
of the screen starting at $20000 to be sent to the SDUMP device. Under
SMS, you will first need to LRESPR SDUMP\_REXT provided on the
distribution disk to use this command. As with ALTKEY, if the specified
key$ is in upper case, you will need to press <ALT><SHIFT> together with
the key, or <ALT> with the key if capslock is on. SDP\_KEY without any
parameters inhibits the hotkey.

**Example**

::

    SDP_KEY p

will cause the screen to be dumped each time that <ALT><P> is pressed.

**CROSS-REFERENCE**
