Extensible Program Call Markup Language

Extensible Program Call Markup Language (XPCML) enhances the functionality and usability of the Program Call Markup Language (PCML) by offering support for XML schemas. XPCML does not support serialization, so unlike PCML, you cannot serialize an XPCML document.

However, XPCML offers several valuable enhancements when compared to PCML:

Specify and pass values for program parameters
Retrieve the results of a program call to your iSeries™ server in XPCML
Transform an existing PCML document into the equivalent XPCML document
Extend and customize the XPCML schema to define new simple and complex elements and attributes

For more information about XPCML, see the following pages:

Advantages of XPCML over PCML
Extensible Program Call Markup Language (XPCML) offers several valuable enhancements over PCML.
Requirements for using XPCML
The Extensible Program Call Markup Language (XPCML) has the same workstation Java™ virtual machine requirements as the rest of the IBM^® Toolbox for Java™.
XPCML schema and syntax
XPCML documents, called XPCML source files, contain tags and data that fully define calls to programs on your iSeries server.
Using XPCML
Using XPCML is similar to using PCML. The following steps serve as a general outline for the actions that you need to perform to use XPCML.
