Expression module
D ESCRIPTION
The Expression module defines expressions and their associated values. Expressions are
referenced in the model by using their name. Expressions can optionally be specified as
one- or two-dimensional arrays.
An expression value may be formed using combinations of integers, real numbers, symbol
names, statistical distributions (e.g., NORM(10,2)), arithmetic operators (e.g., +, *),
parentheses, logical operators, (e.g., .GT. or >), attributes, and variables.
An expression value may be referenced in another expression, but recursive calls to the
same expression are not allowed.
