Logic Assistant 
You can use the Logic Assistant for logic functions; for example, you can look up functions, choose parameters, and then paste a formatted statement into your logic file.
You can look up both Logic module statements and user-defined functions. Use the UDF (user-defined functions) tab of the logic assistant dialog box to look up and use UDF functions. The UDF tab displays both system-supplied functions and user-defined functions.
To use the Logic Assistant
Create a new logic file or open an existing logic file.
Click the Logic Assistant menu on the action pane.
Select the UDF tab to look up a UDF function or the Logic tab to look up a logic statement.
Select a statement category and then choose a statement or function name.
A short description of the statement or function is displayed in the dialog box. To see a detailed description, select the More info button.
Select the Next button. The Logic Assistant displays a statement or UDF function wizard. Depending on the type of statement or function, the system guides you to creating the new logic statement. After completing each screen, select Next to continue.
When you reach the final screen, select the Paste button to add the statement to your logic file.
The logic assistant stays open so that you can create a new statement. Select the Close button when you are finished adding logic statements.
