Syntax Rules

  1. For data-name-3, the same rules apply as for data-name-2.
  2. If the USING phrase is used, data-name-2 and data-name-3 must be described as alphanumeric data items.

General Rules

  1. Data-name-3, if specified, is the table to be sorted; otherwise, the table specified by data-name-2 is sorted.
  2. By specifying USING data-name-3, a second table is used for sort processing. In this case, the elements of the table specified by data-name-3 are transferred to the table specified by data-name-2 and then sorted in the table specified by data-name-2. The individual table elements are transferred in accordance with the rules for the MOVE statement:
    • If the "sending" element is shorter than the "receiving" element, it is padded with blanks;
    • if it is longer, it is truncated.
  3. Transfer of the data-name-3 table elements to the data-name-2 table ends with the last table element of data-name-3 or on reaching the number of table elements for data-name-2. This means that if the data-name-3 table contains more elements than the data-name-2 table, the excess elements are not transferred. If it contains fewer elements, the excess elements of the data-name-2 table are retained unchanged.
  4. Sort processing does not change the contents of the data-name-3 table.
