Expressions

Expressions consist of a value or combination of values (even of different types), variables, attributes, functions, and operators that result in a value. Many consider an expression to be a string expression if it evaluates to a string, a numeric expression if it evaluates to a number, and so on. (For information on how to handle different value types in the same expression, see Converting Between Numeric Types.)

The following are the different expression types used in ProModel:
