Here's how: Make the CHOP Viewer Active. Click and drag the channel to the node you want to export to - after a moment the node will become current and its parameter box will open. Continue to drag to the parameter you want and release. Select 'Export CHOP' from the small menu that pops-up.
A CHOP's exporting can be toggled on and off using the CHOP's Export Flag. Exported data connections are displayed in the network by a gray-dotted data link. An arrowhead shows the direction of data flow, and is animated when cooking to inform you of activity.
When exporting from DATs, the data (character, string, or number) is sent to an operator's parameter. See DAT Export. Both CHOP and DAT Exporting lets you export to parameters that are number values, flags or menus. However DAT exporting also supports exporting to parameters that are text strings, like the text string in a Text TOP, or a path in a Select TOP.
