| ( ) | Function call | |
| : | Function call | |
| . | Member selection | Left to right |

| Comparison operations (have equal priority) | ||
| < | Less than | Left to right |
| > | Greater than | Left to right |
| <= | Less than or equal to | Left to right |
| >= | Greater than or equal to | Left to right |
| == | Equality | Left to right |

Assignment operator
The "=" operator assigns a value to a variable.
For example:
Distance a;
a = Page( 1 ).RectGlobal.Width;
The data type of the expression must be compatible with the data type of the variable.
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.
