1 Introduction
This manual describes how to use PML, the AVEVA Programmable Macro Language. You
should use it together with the Software Customisation Reference Manual.
You do not have to be a professional programmer to start to learn PML, although you may
find this manual difficult to follow unless you have some understanding of programming
concepts such as if statements and do loops. If you have no programming experience, you
should consider attending a PML Training Course. For details, contact your local support
office, whose address is given on the copyright page of this manual.
The current version of PML, sometimes referred to as PML2, may simply be seen as an
extension to the original PML1  facilities. However, the more powerful techniques that are
available mean that many programming tasks are carried out in different ways.
There are some tasks which are carried out more efficiently using PML 1 facilities. These
are described in this manual where necessary, you should also refer to the Database
Management Reference Manual.
