Algorithm Building:-
ALOGORITHM BUILDING:-
A sequence of instructions specifying the steps required to accomplish some task.
A sequence of instructions describing how to do a task.
Algorithms may be presented...
In words
As a flowchart
In structured code
A computer program is an algorithm written for a computer in a special programming language
Example:
Go straight on to the traffic lights, turn left and take the third turning on the right. If the red gate is open then go through it, otherwise go through the green gate.
Debbuging:-
DEBUGGING IS A TECHNIC IN WHICH WE CORRECT ALL THE ERRORS IN OUR PROGRAM.
The ABAP/4 debugger lets you stop a program during runtime and examine the flow and results of each statement during execution.
Stepping through a program with the debugger helps you to detect and correct errors in your code.This documentation is designed for developers new to the workbench’s debugging facilities or for those who want to learn the tool to use the tool more effectively.
Switch on the debugger.
WORKING WITH DEBUGGER.....,
Set and delete static and dynamic break points.
Set watch points
Stop a program at specific key words or events or when a field contents change.
Continue processing after an interrupt.
Display field contents during runtime.
Display the contents of an internal table.
Change field contents for testing purposes.
Change the contents of an internal table.
Display and use debugger’s views.
ABAP LIST VIEWER(ALV):-
ALV GENERALLY WORKS ON TO NOTHIGS 1.LIST DISPLAY AND 2. GRID DISPLAY.
ALV (Abap List Viewer) is a grid control, used for displaying lists. The tool provides common list operations as generic functions and enhanced by user-defined options.
The grid control itself consists of a toolbar, a title and the output table displayed in a grid control. The user has control over the look of the grid (to certain degree) by the use of layout variants.
