The string automation property allows the input of a System.String value either directly or by assigning variable definitions

If a variable definition is assigned that does not provide a string value directly then the display value of that variable is used.

Set Button (Pencil Icon)

Determines whether the value of the property should be set, or retain the current or default value.

If the set button is greyed out then the property is mandatory and must be set.

Special Characters

The square brackets characters [ and ] are used to identify variable definitions

To include these characters in the property use the HTML entity numbers [ for the opening bracket and ] for the closing bracket.
