====== Basics ======

In Autorun, actions are performed through //commands// or //functions//. Their differences and features are described in detail in the [[syntax_type]] and [[commands]] sections.

To separate language constructs, Autorun uses the Windows newline character --- 0x13 + 0x10. As a consequence, multiple statements (such as a command or an assignment statement) cannot be placed on the same line. Thus, in one line can be written:

  * Command (in command record)
  * Function
  * Assignment expression
  * Directive
  * Condition
  * Single line condition with assignment expression or function
  * Loop definition
  * Control keywords
  * Block closing keywords

There are no special block markers in Autorun, code blocks are defined using opening and closing keywords (for example, If ... EndIf).

==== Comments ====

A line starting with # symbol is treated as a comment and ignored. A comment can also be placed at the end of a function expression. Comments are not allowed in the command's line because they can be treated as a parameter. If # is followed by {, it is treated as the beginning of a multi-line comment, if # is followed by } --- as the end of a multi-line comment. Inside a block of multiline comments, there can be both simple comments and nested blocks of multiline comments.

<code autorun>
#{
multi-line
comment

#{
nested
multi-line
comment
#}

# regular comment

#}

a = 1 + 2 # comment at the end of the expression

</code>

Blank lines are ignored.

==== Line splitting ====

Long lines can be split into multiple lines. To do this, use a combination of a space with the underscore character " _":

<code autorun>
MsgBox("Text", _
"Title")
</code>

When merging strings, the " _" combination (including the space) is removed. This combination must be at the very end of the line, comments after it are not allowed.
