PROGRAM DEMONSTRATING (AT EXIT-COMMAND)
program , the screen appears & if we want to come out of the program it will not allow us . We have to
fill the mandatory field on the screen and then we can come out of the program by clicking on the
application tool bar buttons. To overcome this problem , generally we use AT EXIT-COMMAND at PAI of the
screen to force exit from the screen that contains a required field without filling any value to it.
Here we have two screens 9000 and 9001. In the 9000 screen we have an required i/p field & a single
record is displayed on 9001 screen based on the i/p.
