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 single text area (Task comments)that lets you
write comments about the task. These comments are saved when the dialog is closed with the OKbutton,
and are displayed in the Task Comments Pane.
External Program
External Program action tasks are used to launch and execute other programs, which can be useful when
you wish to process your job file in a way that is not possible with the standard PReS Workflow tasks.
Note
As with any task that can refer to network resources, it is important to understand the considerations
involved with paths and permissions of these resources. Please refer to the Network Considerations
page in the Advanced Configuration and Options chapter (Reference Guide, in English only).
There are some important things to consider when using the External Program task:
l The executable file must accept so-called "command-line options" and be able to run without any sort
of user interaction. Only certain programs are able to do this and may refer to it as "command-line"or
"automation"features.
l The process will always wait for the executable file to finish before it continues to the next task, and
does not have any timeout setting. This mean that if your program fails to exit for any reason, your
process will hang.
Input
Any active data file, in any format.
