Basics
In Autorun, actions are performed through commands or functions. Their differences and features are described in detail in the Types of syntax and Commands and functions 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.
#{ multi-line comment #{ nested multi-line comment #} # regular comment #} a = 1 + 2 # comment at the end of the expression
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 « _»:
MsgBox("Text", _ "Title")
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.
