Back to basics - Screen Flow and Screen Sequences .

[rosenberg_eitan]

I was a little bit hesitant if there is a place for such a post but then I decided lets the public be the Judge....

Some time we have to create a program that involve multiple screens .

Program Y_R_EITAN_TEST_08_21 (attached) is a sample program for demonstration purpose .

The program navigation is done by using statements "SET SCREEN dynnr","LEAVE TO SCREEN dynnr" and "LEAVE TO SCREEN 0"
(There are other options please refer to the online help) .

The program will start with "selection screen" and then screen 0100 will be called using "CALL SCREEN 100" .

The program use two levels of "screen sequence":
- 0100,0200,0300,0400 .
- 1100,1200,1300,1400 .

Screens 0100,0200,0300,0400 navigation is done using "SET SCREEN dynnr" and "LEAVE TO SCREEN dynnr" .

Screen 0100 will use "LEAVE TO SCREEN 0" to terminate the "screen sequence" and return to the "selection screen" .

From screens 0100,0200,0300,0400 we can (Using "Function code") "go down" to screen 1100 so "CALL SCREEN 1100" is used
(a new "screen sequence" is started )

Screens 1100,1200,1300,1400 navigation is done using "SET SCREEN dynnr" and "LEAVE TO SCREEN dynnr" .

From screens 1100,1200,1300,1400 we can "go back" to the caller of this "screen sequence" so "LEAVE TO SCREEN 0" is used .

Screens:

Happy navigation .

Because of upload size limit:

- Screens 0200,0300,0400 are a copy of screen 0100
- Screens 1200,1300,1400 are a copy of screen 1100
