Constants

The FlexiLayout language uses only global constants. Global constants are set in the FlexiLayout Properties dialog box (see Global Constants) and can be accessed from any section of any block or element description.

Comments

You can add comments to the code. The comments have the same format as in the C language and can be written in one of the following ways:

  • The /* (slash, asterisk) characters, followed by any sequence of characters (including new lines), followed by the */ characters.
  • The // (two slashes) characters, followed by any sequence of characters. A new line not immediately preceded by a backslash terminates this form of comment.
