The SET command is used to populate the outbound document object.

Fragments use only fields, so the SET FRAGMENT command requires the SERVICE_EXCHANGE(*FIELD) keyword.

Lists use only a working list, so the SET LIST command requires a working list argument.

Note: List and Fragment keywords

There are two possible ways to add a list of data when creating an XML document.

  1. The most obvious way is to use the SET command described here with the LIST keyword, then specifying the array in a working list. With this approach, the section of XML would need to be defined as a list in the XML Binding Wizard.
  2. Alternatively, the same could be achieved by using the FRAGMENT keyword inside some looping code. Each loop would add a new row to the list. XML documents and readers will automatically pick up this repeating sequence as a list. With this approach the section of XML would need to be defined as a fragment in the XML Binding Wizard.

Whichever way you choose, you will need to carefully decide whether the relevant section of XML is defined as a List or a Fragment.

Note: Instruction keyword

If you wanted to add an XML processing instruction as follows:

    <?xml version="1.0" encoding="utf-8"?>
    <?xml-stylesheet type="text/css" href="mystyles.css"?>


then you could use the following command:

    SET INSTRUCTION(xml-stylesheet) DATA(type="text/css" href="mystyles.css")
