In the Command Program, you can interactively evaluate expressions, from simple statements involving a single variable to complex mathematical expressions involving many different events, variables, and functions.
Assume your compiled model is a program containing the following definitions.
value LastYrsSales = 36075; value DMarkToDollars = 1.55;
A command to display the value of a variable can be as simple as the name of that variable. For example, to display the value of the variable LastYrsSales, you can type the name of the variable as a command.
LastYrsSales
When you click Execute | Run, the number represented by LastYrsSales is displayed in the Log window.
LastYrsSales = 36075;
If you did not compile the program before executing the command, DPL will display the error message Value not found.
The name of a variable is a simple DPL expression, consisting of a value name and no operators. Expressions can also be complex. Suppose the Sales Director wants to know last year's sales in dollars instead of German Marks.
LastYrsSales/DMarkToDollars;
The Session Log displays the result.
LastYrsSales / DMarkToDollars = 23274
In the preceding examples, LastYrsSales and DMarkToDollars did not depend on any conditioning events. However, if a value depends on conditioning events, the states of those events must be known for DPL to know which number is represented by that value.
