PML Directives

PML Customisation User Guide

PML directives are commands used to control PML itself.

Note:

Unlike the PML commands described in How Forms are Loaded and Displayed, PML directives should not be included in callbacks, but are generally for command line use.


Command	Effect
pml rehash	When you create a new PML form while an AVEVA product is running, you must link in the file storing the form by giving this command.
	It causes PML to scan all the directories under the PMLLIB path, and to create a file pml.index, which contains a list of all the .pmlfrm files in the directories.
pml index	This command re-reads all the pml.index files in your search path without rebuilding them.
	If other users have added PML Files and updated the appropriate pml.index files, they can access the new files by giving this command.
pml reload form !!formname	When you edit an existing form while an AVEVA product is running, you must use this directive to reload the form definition file.
kill !!formname	If you experience problems of an edited form definition not being re-loaded, you can use this directive followed by the pml reload directive.
pmlscan directory_name	This command runs a utility supplied with AVEVA products. When you are not running an AVEVA product, you can use this command to update the pml.index file in a given directory. Refer to the Installation Guides for further information.

Refer to Developing PML Code for tracing commands that will be useful when you start to develop PML code.
