FoxPro 2.x

NOTE: This example assumes that the CUSTOMER.DBF table has been installed in FoxPro's TUTORIAL subdirectory.

To display any column of an array in a list or popup, use the Screen Builder to perform the following:

1. In the Setup Code snippet of a test screen, type the following:

        SET DEFAULT to <FoxPro_directory>\tutorial
        SELECT company, city, state FROM customer INTO ARRAY a3colmns
   							

2. Create a list or popup object. For a list, select the From Array radio button. For a popup, select the Array Popup radio option button.
3. Type A3COLMNS in the Array Popup text box.
4. In the Variable text box, type "M.COL" (without the quotation marks).
5. Choose 1st Element.
6. Verify that the Expression radio button is selected. Then type the number 1, 2, or 3 in the text editing region. The number you type designates which of the three array columns will be displayed.
7. Generate and run the screen.

NOTE: The first column of the array contains COMPANY field data, the second contains CITY field data, and the third contains STATE field data from the CUSTOMER.DBF table.
