Using the Application Parameter List
[REV BEG]
The MPE/iX Shell allows you to specify parameters to applications. The
shell passes these parameters as arguments to your application to be
processed by the application. Following is an example of how to specify
the display parameter.
$PIZZA -display HPMYDISP:0.0
In this example the PIZZA program accepts the
-display string as a parameter. Because PIZZA uses Xt, the standard
-display option is extracted by Xt and is used during the connection to
the display server whose node name is HPMYDISP.
Note that the command line specification of the display overrides that
given in the DISPLAY variable.
Some computer systems can support multiple users with graphic displays on
a network. On these machines, a display number is used to indicate which
monitor of the specified network node should be used. In the example
given above, the HPMYDISP:0.0 informs the application to connect to an X
display server on a machine whose network node name is HPMYDISP, and use
screen zero to show the information.
