Extending the configuration
Now that you are an “experienced” ProTool user, you can extend your configuration by another screen.
Open a new Screen with the menu item
Insert
→
Screen
.
Now select Edit
→
Properties and change the screen name:
Parcels_1
.
In this screen, enter the number of parcels to be transported. At the same time you want to display the
current counter status.
This is implemented as follows:
The maximum number of parcels is entered via an input field.
The number of currently counted parcels is displayed as the output field.
Configuring texts
So that you can distinguish the input field from the output field, configure a text in front of each field.
Select the first line of the first screen entry with the cursor and enter the text:
Max.number:
. Then
position the cursor in the first line of the second screen entry and configure the text:
Curr.number:
Then define the fields for the input and output.
