Correct “Ends” force us as programmers to put the appropriate “Endxx” at the end of a set of logic. It’s a small thing, but program clarity is improved. Listing 4-4 illustrates the use of If, Else, Elseif, and Endif operations in free format. If A = B; FieldA = FieldB; Else; FieldA = *Zero; Endif; // Simple If, Else, and Endif // An If, Elseif, Else, and Endif group If Option = 'A' and (Type = 3 or Company = 73); Value = 1; Elseif Option = 'B' and (Type = 3 or Company = 75); Value = 2; Elseif Option = 'C' and (Type = 1 or Company = 99); Value = 3; Else; Value = 4; Endif; Listing 4-4: Examples of If, Elseif, Else, and Endif Chapter 4: Introducing Free-Format RPG IV • 37 Controlled Looping Controlled looping is another common function in RPG, and IBM made some changes for free format in RPG IV.

In the calculations, the %Kds built-in function is used on the Chain, Set, or similar operation. This function has two parameters: the named data structure mentioned above and an optional constant that specifies how many key fields to use from the data structure in the operation. If omitted, the second parameter defaults to all key fields. The second method available is the inline composite argument list, provided on the calculation operation line. You specify fields in a parameter-style list, and, together, these fields comprise the lookup key argument.

You can use a partial key in the key argument list as well. This combination can provide a valuable utility if the file being accessed has a multiple-field key. For example, say you have an “on-order” file with a two-part key: customer number and order number. To determine whether a certain customer has one or more data records in the file, you need only code a Setll to the file, using the customer number as the argument, and then check the status of %Equal after the Setll. If the function returns '1', data exists for the customer, and the file pointer is positioned at the first record.
