Custom Dialogs for Extension Commands

Since custom dialogs generate command syntax, they can be used to generate command syntax for an extension command. As an example, we will create a custom dialog for the SPSSINC RASCH DEMO extension command described in Creating Extension Commands.

The SPSSINC RASCH DEMO extension command has the syntax diagram shown here. The custom dialog will generate this syntax, substituting the variables and missing value treatment, if any, specified by the user.

SPSSINC RASCH DEMO 
/VARIABLES ITEMS=variable list
[/OPTIONS MISSING={LISTWISE**  } ]
                  {ALLAVAILABLE}
