You can create comment lines or create a comment following a statement. The ABAP compiler ignores comments. To designate an entire line as a comment, place an * (asterisk) in the first position:

Remove the initial * (asterisk) to uncomment a line.

To make a whole block of code into a comment, select the block and choose Block/Buffer ® Insert comment *. To restore a commented block to a normal block, select it and choose Block/Buffer ® Delete comment *.
