difference between the window object and the report object in JSL

[#1]

during learning JSL, I'm still confused about the  the window object and the report object in JSL. After using platform object, i can use the report or window object to store my analysis information, so is there any differnce between the window object and the reportobject in JSL?  any clear definition ?

I think Introduction to the JMP Scripting Language has some explanation on this on 5.1 and 5.2 chapters. Scripting Guide can also provide some help for example Scripting Guide > Scripting Platforms , Scripting Guide > Display Trees > Structure of JMP Reports and Scripting Guide > Display Trees > Construct Custom Windows .

Both platforms and reports can (and do) reside within windows and can take different messages. From scripting guide:

"Platform object references and report object references receive different types of JSL messages. Platforms can run tests, draw plots, and so on. Reports can copy pictures, select display boxes, or close outline nodes".
