I would really love to have a FileMaker Include Script Step. Ideally, it would function just like php's Include function. "Why?", You might ask. "We already have a perfectly good Perform Script Script step. That lets me break up my code into smaller chunks".
Yes that is true, but when you call Perform Script, you get a brand new script, with its own variable scope. I would love to be able to have the option to "include" a script in the current one. That included script would run in the exact same Variable scope as its parent.
It would solve this common problem.
A script declares several variables at the top of the script, then it calls a subscript. If that subscript needs any of those variables you have to make sure to pass them explicitly. That is easy enough if there is one or two, but if there is a lot of them it gets tedious.
