Subprogram: Find First Occurence (Example 11) about animation_nodes_manual

[OmarEmaraDev]

The dummy parameter is the parameter called index, we add it just as any other parameter, but, we set its default value to -1, use it as an output and hide it as an input. All of this can be done from the advanced node settings of the parameter.

The order of operations in the loop is as follows:

1. Parameters and iterators are fed to the loop.
2. All nodes in the loop are executed.
3. Break—if available—is executed.
4. Generators—if available—is executed.
5. Reassignment—if available—is executed.

So the breaking happens before generators or reassignment operators are executed.

Thanks for bringing this to our attentions, we shall add it in the documentation.

Thank you, in particular for the processing order.

Re the dummy parameter, the funny thing is, as mentioned I didn't know how to do this, but yet my program *apparently runs flawlessly without it.

I probably need to check the veracity with more outcome. But so far I think I get the results you do without this dummy value.

I can try to reread what you wrote to understand better what you are doing there with the dummy value (and subsequently why I need it in the Subprogram routine).
