Topic 7.2.2: Expression Elements

  • Expression Elements
    • The following sections describe, in detail, the elements available for constructing expressions.
  • Operators:  An operator is a symbol used to manipulate the value of one or more operands. Below is a list of valid operators from highest precedence to lowest.

  • Operands: Operands can be of type Boolean (True or False; also referred to as Discrete), Numeric (any positive or negative number) and String (alpha-numeric string of any length). Below is a list of valid operands.

  • Functions: There are seven functions currently available. All of the functions are available in the Recipe Editor. However, only the Not function is available in the Process Log Editor application.
    • Functions are used to do more than simply check if A=B, A<B, or A>B. They are used to interact with User, Delay Actions, etc.

  • Delimiters: There are five delimiters used to identify operands and to build expressions within expressions (recursive expressions).
