As a subclass of popstring class, popasl can be used to pop up any kinds of standard system asl requesters. A seperate task is spawned to handle these requesters, the application continues to run.
Using an asl popup class, you don't need to worry about handling asl requesters. MUI will automatically open one when the popup button is pressed and update the corresponding string gadget when the user terminates the requester. From the programmers point of view, all you have to do is to handle the string gadgets contents.
IMPORTANT: At object creation time, you can use all ASL library tags as well. They will be passed to the AllocAslRequest() call without further interpretation.
