Propably this can be done using "job mailbox", but I can not find a documentation regarding it. I have found how to change to specific sreen number, but I should also be abte to know which sreen is open! HELP!

Best regards, Wizard

I copied the screen no. 1 to screen no 8, and now when I go to page 8, the sreen number word iat area pointer is not updated to 8, instead it stays as a number of previous screen.
