AS/400 Toolbox for Java \ PCML

Program Call Markup Language

Overview

Program Call Markup Language (PCML) is a tag language that helps you call AS/400 programs, with less Java code. PCML is based upon the Extensible Markup Language (XML), a tag syntax you use to describe the input and output parameters for AS/400 programs. PCML enables you to define tags that fully describe AS/400 programs called by your Java application. For more information about XML, see the XML reference section.

A huge benefit of PCML is that it allows you to write less code. Ordinarily, extra code is needed to connect, retrieve, and translate data between an AS/400 and Toolbox objects. However, by using PCML, your calls to the AS/400 with the AS/400 Toolbox for Java classes are automatically handled. PCML class objects are generated from the PCML tags and help minimize the amount of code you need to write in order to call AS/400 programs from your application.

Platform requirements

Although PCML was designed to support distributed program calls to AS/400 program objects from a Java platform, you can also use PCML to make calls to an AS/400 program from within an AS/400 environment as well.
