View the exhibit.
In the OrderltemsForm, you have a control with a button that users can click to navigate to the first record in the block. The button has keyboard Navigable and Mouse Navigable set to No.
You are coding a When-Button-Pressed trigger for the First Record button with the following code:
SCROLL_UP;
WHILE FORM_SUCCESS LOOP
SCROLL_UP;
END LOOP;
What happens when the user clicks First Record with the cursor in the 72nd record in the block, as shown in the Exhibit?
A. The cursor successfully navigates to the first record.
B. A runtime error is encountered because there is no scroll bar for the block.
C. The display scrolls so that the first record is visible, bur the cursor stays on the last visible record, which should be record 10.
D. The form goes into an infinite loop and has to be killed by using operating system commands.
E. internal navigation to the first record occurs, but the visible cursor remains on record 72. You should add the SYNCHRONIZE command to synchronize the display with the internal state of the form.
