ENDLOOP to program step loops in a screen in both PBO and PAI. In a fixed size loop the number of loop blocks shown in the screen is fixed,while in case of variable size step loop the number of blocks will change dynamically according to the size of the screen.There could be only one variable step loop per screen and unlimited fixed size step loops per screen.Ī step loop can extend more than one line on the screen(see Table Control).A vertical scroll bar is automatically created to show step loops on he screen. A step loop, as a screen object, is simply a series of field rows that appear as a repeating block. In a step loop number of screen elements are combined together to form a loop block. They are repeated sequence of blocks of screen element. The STEP LOOP are the predecessor of TABLE CONTROL they are used to display tabular data on the screen. The structure of table controls is different from step loops. TABLE CONTROLS are simply enhanced STEP LOOPS that display data with the look and feel of a table widget in a desktopĪpplication. TABLE CONTROLS are always single lines, but can be very long.
