Substack vs. Library Stack

[William Prothero]

Scott:
I use substacks as code libraries in a large project. The substack handlers are callable (without specifying the substack name) from any other substack and also from the main stack. It is like having a giant stack script. Of course, you have to “Start using mySubstack” to make the code available. You can also remove the substack and use it elsewhere and attach it to another main stack by setting its mainStack property. e.g. set the mainStack of this stack to “myMainStack”.  

I find it very convenient. But, as I get more familiar with Livecode, I’ll like the libraries approach. 

Best,
Bill
