Chapter 2 Processing ASCII characters
For example, in a sorting operation, an array of a user-defined data type creates a
table that shows the lane number for each type of product. To determine which
lane to route a product, the controller searches the table for the product ID
(characters of the bar code that identify the product).
To look up a bar code, follow these procedures:
Create the PRODUCT_INFO Data Type on page 21
.
Search for the characters on page 21.
Identify the Lane Number on page 22.
Reject Bad Characters on page 22.
Enter the Product IDs and Lane Numbers on page 23.
