Asking for user input in the middle of a function

Question

Here's my issue.
I need to launch and input window in the middle of a function for user input.  Before I can continue through the function I need a response back from the user first.  Psuedo code below:
function
     function begins
     pop up window is launched to ask for user input
     function continues after users submits input
     user input from pop up window is used in function return value
Let me know if you need more clarification but this is essentially what I'm attempting to do.

Answer 1

The way actionScript works it isn’t really designed to work that way
Is there any reason why you have to only use one function as you have written
I think you really do need to split up your code into sections that a, set up the pop-up with  event listeners waiting for the input to be completed, trigger the pop up with user input, then have a handler function that then interprets the results of the user action.
Trying to force the system into a closed loop while waiting will be a bad idea.
By using a pop-up or an alert window that is set to be modal, you are effectively stopping your application doing anything else until the user input has been completed, but still not locking the app into a closed loop. Imagine what would happen if you did put the system into a closed loop, the mouse movement wouldn’t be updated, the screen wouldn’t refresh and the system wouldn’t be able to handle your user input. the reason for using async model is you are able to let the system still do all its background task (move the mouse, give inputs focus, keep the screen drawn etc) but still tell a part of your app to ‘wait for input’ before carrying on it execution of your logic
Do you come from another programming language? Maybe one that uses less of an OOP approach? I only ask, as the method you are describing is much more like how I had to program when  I worked on computers years ago as an assembly programmer.
In actionscript and most other modern languages and Oss you don’t have total control of the system and cant lock it into an action as you describe.
You need to have an asynchronous approach to situations like you describe and let the system run in the back ground while you are waiting for input (or date from a server for that matter)
Please excuse me if I am telling you things you already know.
What exactly is your use case for this? Maybe if we knew exactly what you are working on I might be able to offer a solution that would make sense for your particular situation.
Hope all is going well and please feel free to contact me if you are stuck
