Editing ABAP (section)

===Comments===
ABAP has 2 ways of defining text as a [[Comment (computer programming)|comment]]:
* An [[asterisk]] (*) in the leftmost column of a line makes the entire line a comment
* A [[double quotation mark]] (") anywhere on a line makes the rest of that line a comment

Example:
<syntaxhighlight lang="abap">
