Just writing this down in case I forget just had an idea for doing a link call from within the node

OK - lets see where this goes Ignore Blocky for the moment -assume I'm writing a function node Can I (in anyway, shape or form) make a call to a link node and have it return to my function? i.e. use an external link flow as as a subroutine?

Yes! But it's a secret, and could be seen as corporate espionage (unless I have it wrong? - extremely possible) [image] Send a message from a custom function node without output option General Yes, but it's a secret shushing_face The link out node communicates to a lin…

Without trying to get my head around all that just yet - will it let me call link node and then return back to next line within the function node?

You have a sick mind @cymplecy ! :smile: I don't actually know from the top of my head

I can't imagine wanting to do it but if the function has two outputs: [image] [{"id":"37c2582930360eff","type":"inject","z":"c6109153bf0ba2c5","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"…

Yes - its easy to that :slight_smile: I'm after the trick to return it back to the point it left in the code within the function node

A more "Node-RED'y" approach for sure. Looking at the code for the link-call node, I don't see how you could squeeze something into a function node that would replicate it. Also, it creates a hidden connection which might well be very confusing. I guess the real question is - what are you wanting …

function linkrun () { if (! msg.linkrun) { node.warn ("not run") return [msg, null] } } linkrun() node.warn ("Am I not the next line?") return [null, msg];

But, of course, the "returned" message creates a NEW instance of the function node, it is not the same instance. So if you need to follow on using anything previously calculated, you would have to temporarily save that status and recover it. So you would also need a unique reference to pass across.

Different instance of the function maybe but it's the same message, so any message properties are safe?
