Data Types

Values in LISTSERV Maestro formulas can be of one of five different data types:

Number: The value is an integer number in the following range:
-9223372036854775808 to 9223372036854775807
Note: Floating point numbers are not possible in Maestro formulas.
Text: The value is a character string that may contain any sequence of characters (including an empty sequence).
Boolean: The value is a boolean value, i.e. either "true" or "false".
Number Set: The value is a set of numbers. Such a number set is a collection of distinct values of type "Number", i.e. each number can be contained only once. The set can either have no elements (an empty set), have only a single element, or have any other number of elements.
Text Set: The value is a set of text strings. Just like a number set, such a text set is a collection of distinct values of type "Text" that can have zero, one, or several elements.
