ABAP stands for Advanced Business Application Programming.
It is a programming language developed by SAP.
- ABAP is not case sensitive.
- WRITE is the keyword to print on screen
Example:-
WRITE 'Hello ABAP!'.
Chained statements.
If consecutive statements have identical part at the beginning, then you can chain these statements into a single statement.
First write the identical part once and then place a colon (:). Then write the remaining parts of the individual statements separated by commas.
Example - Normal Statements:-
WRITE 'Hello'.
WRITE 'ABAP'.
The Above statement can be written in Chained Statement as,
WRITE: 'Hello', 'ABAP'.
If you want to print the texts in new line, then you can place(/).
WRITE: 'Hello',/, 'ABAP'.
The above statement will print 'Hello' in one line and 'ABAP' in another line.
Comments.If you want to make the entire line as comment, then enter asterisk (*) at the beginning of the line. You can also use (Ctrl + < ) to add and (Ctrl + >) to remove a comment.
Example:-
* This is a ABAP Comment line
If you want to make a part of the line as comment, then enter double quote (“) before the comment.
Example:-
WRITE 'This is a Comment'. "Start of comment
