You are here: Building the Logic > Logic Builder > Using the Logic Builder > Selecting Statements
The first thing to do in creating a statement with the Logic Builder is to select the desired statement from the statements list box. You can restrict the list of statements to choose from using the Statement Type combo box above the statement list. If you are just starting to use ProModel, you may want to select the Basic Statements type to list only the most commonly used statements.
To select a statement, left click on the statement name in the list box. The statement name appears in the logic text box along with a brief description. The parameter buttons also appear just below the logic text box.
Before you begin editing the parameters of the statement, you can select a different statement. However, once you begin defining a parameter, you must click the Clear button to abandon that statement and select another.
