Predefined Function Documentation
The RPL predefined function help content is now shown within the RiverWare interface in the following dialogs:
• Predefined Function Editor dialog. (Below Right)
• RPL Palette, on the Predefined Functions tab. (Below Left)
• RPL Set Editor when Show Predefined Groups and Show Descriptions are checked.
RPL Parameters
The following parameter setting were removed as they no longer incur performance overhead.
