Advice, please - how to program something like a nested "if"

[simonw]

Greetings

 

I am spinning a web with dozens of programs acting as occupancy sensors and countdown timers and running time meters, and so far so good, this is great and I appreciate the valuable ideas and tips here on the forum.

 

Sometimes I want program A (something that determines occupancy, say) to call an If statement in program B (like turn lights on of they're not already on and it's dark outside), - but - I don't want program B If evaluated unless I call it from another program. In practice it seems like Program B just does its sweet thing and so my approach is useless.

 

Could Folder Conditions be made to help somehow??

 

I welcome suggestions about the right "ISY way" to go about this sort of task. Thanks in advance,

 

Simon

Mark Program B Disabled. It can still be called from another Program but will not trigger the If on its own.

Perfect - thank you, Lee.

 

This also explains why I have had puzzling results debugging program chains using "disable" ...

 

Have a great day,

Disabled programs function very much the same as callable subroutines.

 

One point, however, calling these "subroutines" does not necessarily happen in order. In other words, if you have 2 "run ifs", the first one doesn't necessarily execute before the second one.
