Referencing Two Different Files
Referencing Two Different FilesTip10.scr, illustrated in Figure 123 on page 153, uses two data files: one that contains item numbers and one that contains item descriptions. Records in both are sorted identically. By referencing data in both files, this example displays the description of an item whose number is entered by the user.

Display: SCAN Prompts the user to enter an item number or press <F4> to quit.
Input: ITEM Stores the input entry in the default register.
Verify: <F4> Checks to see whether the user pressed <F4>. If so, the program returns to the main frame.
Verify: IN FILE Checks the contents of the default register against the file with the items in it. Figure 124 on page 154 shows the settings in the dialog box for the node.
