Editing Asterisk (section)

=====Comments in programming languages=====
{{Main article|block comments}}
In the [[B (programming language)|B programming language]] and languages that borrow syntax from it, such as [[C (programming language)|C]], [[PHP]], [[Java (software platform)|Java]], or [[C Sharp (programming language)|C#]], comments in the [[source code]] (for information to people, ignored by the [[compiler]]) are marked by an asterisk combined with the slash:

<syntaxhighlight lang="c#">
 /* This section displays message if user input was not valid
    (comment ignored by compiler) */
</syntaxhighlight>

[[CSS]] also uses this comment format:<syntaxhighlight lang="css">
body {
  /* This ought to make the text more readable for far-sighted people */
  font-size: 24pt;
}
</syntaxhighlight>

Some [[Pascal (programming language)|Pascal]]-like programming languages, such as [[Object Pascal]], [[Modula-2]], [[Modula-3]], and [[Oberon (programming language)|Oberon]], and other languages such as [[ML (programming language)|ML]], [[Wolfram Language]] ([[Mathematica]]), [[AppleScript]], [[OCaml]], [[Standard ML]], and [[Maple (software)|Maple]], use an asterisk combined with a parenthesis:

<syntaxhighlight lang="Applescript">
 (* Do not change this variable - it is used later
    (comment ignored by compiler) *)
</syntaxhighlight>

Each computing language has its own way of handling comments; {{code|/* ... */}} and similar notations are not universal.
