PPG Tutorial

2.On the Input From tab, the Input From checkboxes let you indicate which sources of input you want the portable to accept. Select the Scanner, Data Key, and Function Key checkboxes. This allows the user to input data by scanning or pressing keys.

Figure 86. The Input: Item Properties Dialog: Store Info Tab

•A pull-down list appears next to each selected checkbox. Specify a separate Link To setting for each type of input allowed.

•Select scanner and data-key input to Link to the Verify: Input node.

•Select function key input to return the user to the Main Menu.

3.If you want the user to view the data while it is entered, enable the Echo to Display checkbox on the Display tab. This displays the char- acters entered with the data keys on the portable’s screen. To specify the exact position on the screen, select Specify Position.

The Echo to Display option displays keyed-in characters only until the user presses the <Enter> key. Once the data is entered (or scanned), the program moves on through the next nodes and redisplays the menu text, overwriting the echoed charac- ters.

To avoid this, you must add Output nodes to reposition the cursor and display the echoed characters on a different line. This is demonstrated later in the tutorial.

4.Select the Specify Position checkbox. Position boxes become avail- able, allowing you to indicate the exact row and column you want the echoed data to begin on.

•Position it on the second row and first column.

•Columns and rows are numbered starting with 0 instead of 1; so enter 1 in the Row field to indicate the second row and 0 in the Col field to indicate the first column.
