When you create an
expression event (one that uses *’s to populate variables), you use this screen
to determine what variables get populated by which * in the event text. This process is explained in more detail in
the events help file.
Select Variables Screen Elements
Event Text Field
This read-only field
simply displays the text for the event you are working with.
This read-only
field simply displays the text for the event you are working with but populates
the *’s with the variables you have selected.
It is designed to give you an example of what variables will be
populated by what part of the event text.
Available Variables
List
Lists all variables
available for you to populate. The blue
@ designates a user-defined variable, the green @ signifies a system variable
and the fuschia @ designates a system-resident variable.
Lists currently
selected variables to be used with this event.
The variable names will be placed into the example text to show you
where they will be populated from in the event text. A yellow @ signifies a dummy variable.
Moves the currently
selected variable in the Available Variables List to the Selected Variables
List. Double clicking on the Available
Variables List will do the same thing.
Moves the currently
selected variable in the Selected Variables List back to the Available
Variables List. Double clicking on the
Selected Variables List will do the same thing.
Adds a dummy variable
to the selected Variables List. Use
dummy variables for when you want to use a * to match a certain text pattern in
an event, but don’t really want the value to be saved for use. Any value parsed to a dummy variable is
tossed away. Dummy variables will
appear as <@> in the Example field (and in the Events screen).
Moves the currently
selected variable in the Selected Variables List up or down in the list. This allows you to move the selected
variables to any * position in the event text.
Pressing this
button brings up the Variable Maintenance screen. Here you can create or edit user-defined variables.
Note: If you open the
Variable Maintenance screen from this screen, you will not be able to delete any
variables. Open the window from the main
screen menu to do this.
Selects this
variable assignment for this event and closes the screen.
Closes the screen
without making any changes to the event.
