Screen programming - Return statement

Former Member — Mon, 10 Jan 2011 10:49:58 GMT

Hi,

In the middle of a user exit, I have called a screen in which two buttons are there "SAVE and Exit".

If save button is pressed, data should update the value is table and continue with the user exit.

If exit button is pressed, nothing should happen and continue with the user exit.

My problem is, i have called this screen in the middle of the user exit. Exit button works fine, it continues with the next line of the code in the user exit.

But for save button, after updation, it returns to the first line of the user exit. But it should continue with the next line in the user exit.

Which statement will bring the control to next line of the user exit after updation.

Thanks in advance,

Ezhil.

What screen are you calling? Please paste the code for SAVE user-command.

If you call the screen using CALL SCREN XXX then LEAVE TO SCREEN 0 should be enough.

However the exit might somehow try to process SAVE function too. I suggest you use different function code in your screen to enter SAVE mode.

LEAVE PROGRAM unloads the program from the memory. By using LEAVE TO SCREEN 0 you simply end up current screen call sequence. This causes to return to the following intruction after CALL SCREEN, hence continuing your program execution.

Try with:

SET SCREEN 0.
LEAVE SCREEN

instead of LEAVE PROGRAM
