Common Errors
Though some error messages are specific to a task in particular, others may apply to any and
all tasks because they are related more to the system than to PReS itself. Some examples
would be W3813, W3830, W3991, W4005. These correspond to issues such as not having any
space to write files, permission errors on folders or files, etc.
Comments Tab
The Comments tab is common to all tasks. It contains a text area (Task comments)that lets
you write comments about the task. These comments are saved when the dialog is closed with
the OKbutton, and are displayed in the Task Comments Pane.
Check the option Use as step description to display the text next to the icon of the plugin in
the Process area.
Run Script
Run Script tasks are used to run scripts that typically perform some kind of processing on the
job file received by the task. Scripts are often simpler to write than programs added with the
External Program action (see "External Program" on page317). However, they can be slower
to execute.
The Run Script action task can be used either as an action or a condition. When dragging and
dropping a Run Script action task on a given process, you select whether to use this task as an
action or a condition from a contextual menu.
For more information on scripts, what languages are supported and how to write scripts and
conditions, please see the related chapter, "Using Scripts" on page89.
