PROGRAM zkmalvev.
* 1. SE38: create executable program (type 1), use PROGRAM
* instead of REPORT because it will have screen and modules
*
* 2. SE80: create screen 0100
*
* 3. Screen Painter: on the screen 0100 create 'Custom control'
* CONT1_0100
*
* 4. SE80: for screen 0100 set the variable OK_CODE for the element OK
*
* 5. SE80: create calls to PBO and PAI in the flow logic of screen 0100:
*
* PROCESS BEFORE OUTPUT.
* MODULE pbo_0100.
* PROCESS AFTER INPUT.
* MODULE pai_0100.
*
* 6. SE80: create GUI Status STAT_0100, assign functions EXIT and SAVE
* to standard icons, eventually create your own toolbar button
