Script Statement: Creates a script variable as a constant with a specific value.

Syntax

:C[ONST[ANT]] Variable name = Value

Syntax	Description/Format
Variable name	The name of the script variable that should be defined as a constant. You must always use an ampersand symbol (&) that precedes the script variable's name, and it is recommended that you use a hash (#) symbol to signal the end of the variable's name. The length of a script variable's name is limited to 32 characters. All characters of the alphabet, the numbers 0-9, and the following special characters can be used:"$", "_", "@", "§" and "#". German Umlauts are not allowed. The first character after the leading "&", which is not part of the 32-character limit, must neither be a number nor a "$" symbol. For more details about the syntax, see Syntax Format: script variable
Value	The value of the constant. Format: script literal, script variable or script function This value cannot be changed subsequently.

Comments

This script element creates a new variable as a constant and assigns a specific value to it. As opposed to variables that you create with :SET, the values of constants are write-protected and cannot be changed subsequently.

Important!

You cannot use this script element to convert an existing script variable to a constant. This includes that you cannot use a name of an existing variable.
You cannot create a constant with :DEFINE. This includes that they do not have a certain data type.
:CONST automatically rounds floating-point numbers up or down. To save floating-point numbers, use :DEFINE.

Examples

:CONST &COMPANY# = "CA Technologies"
:CONST &PI# = 3.1415
