As we can make new panel in ISPF and can open in popup window also so is there any way to do the same in CICS screen? Like if I press any key the new screen should open as popup and as per the size as we want it.
It is possible to have pop-up screens in CICS.
Create a partial map (smaller in size than the normal size of 24,80) which you would like to send.
Provide a suitable location of the map on the screen(LINE=n,COLUMN=n)
Remember the area you are using to send the partial map does not have any data of the full map which is already displayed.
While sending the partial map, do not use ERASE option which will erase the entire screen area.
