WatchSessionValue - what is the p_watch parameter

[CaseyR]

Hi, Bruce

A few weeks ago you showed the WatchSessionValue method in an NT User Group session.   Updating to 9 from 8.71 changed the method prototype, making the p_watch parameter required instead of optional.    What are the value options and what do they do?

Thanks.

Watching can be done by a human (for debug reasons) or by a page (for WebSocket reasons)

net:WatchDebug
turn watching on for this value to debugview

net:WatchSocket
when value changes send new value to the clients watching this value.

-net:WatchDebug
stop watching this value to debugview

-net:WatchSocket
stop watching this value for web sockets.

Great.  Thanks.
