SAP ABAP — Basic Syntax
Basic Syntax
Each ABAP statement starts with an ABAP keyword and ends with a period. Keywords must be separated by at least one space.
The first line in the ABAP program begins with the word REPORT. As and when you execute the program you have to start with the first line of the word REPORT only. The program name which was created previously is followed by the statement and the line ends with a period.
Statements consist of a command and any variables and options, ending with a period. It is this period that marks where the statement finishes.
SAP ABAP is not a case sensitive program. The result of the encoding data is the same.
How to use comments in the SAP-ABAP?
Comments can be placed anywhere in the program by two methods.
· Comments are indicated by placing an asterisk (*) in the first position of the line, in which case the entire line is considered by the system to be a comment.
· Also we could use double quote (“) after a statement for comment.
Collectively Commenting the Code
We could convert the code with “Ctrl + <” also by following the Format → Comment Out Lines.
Colon Notation
If you want to write series of statements at a time, you can give the statements together with the colon (:) operator and commas. Consecutive statements can be chained together if the beginning of each statement is identical.
Here is an example of a program that could be written using colon statement:
