hi this is ramu.my question is :set-screen,call-screen and
leave screen differences and when we use those statement
while implimenting code.please help me .iam in trails now..

Answer Posted / karthik

With SET SCREEN current screen simply specifies the next
screen in the chain and control branches to the next screen
as the current screen has been processed.

If we want to branch to the next screen with out finishing
the current one then use LEAVE SCREEN.

With CALL SCREEN the current(calling) chain is suspended
and a next screen is called.The called can then return to
the suspended chain with the statement LEAVE SCREEN TO SCREEN 0.
