Literal Values, Variables, and Operators

Expressions are composed of at least one of the following elements:

• Literal Values

• Variables

• Operators

Tool input parameters expect data of a specific type. There are three ways to enter that value into the parameter:

• You can type a literal value, such as "User Queue: Stephen Schiller" or 1970.

• You can specify a variable such as StrUserQueue or IntBirthYear.

• You can build an expression with Operators that produce the desired value, such as GetYear (dtBirthyear)
