Using Alf with Cameo Simulation Toolkit - Part 2: ModelingEd Seidewitz
Alf is an OMG-standard textual language with a familiar Java-like syntax, but it is designed specifically to be used in the context of graphical, executable UML and SysML models. This language is available for use in No Magic's Cameo Simulation Toolkit (CST) v18.5 to write expressions and behaviors in executable UML. This presentation follows on from "Using Alf with Cameo Simulation Toolkit - Part 1", covering the use of Alf for specifying behaviors in models of multiple, communicating objects, including synchronous operation calling and asynchronous signal sending.

PT1420: Modules in Flowchart and Visual Basic
Page 1
This lab requires you to think about the steps that take place in a program by designing a
flowchart. Use an application such as Raptor or Visio. Read the following program prior to
completing the lab.
Data Communications Corp wants a small program that will calculate the cost of UTP it
installs for their clients. Write a program that will ask the user to input the name of the
client and the number of feet of cable installed. The program should then calculate and
display a final bill. Cost per foot of UTP is .21 cents. Be sure to add on a tax of 6%. Final
bill should include the total cost and client name. Be sure to add modules to your
program.
Step 1: In main, create a module called declareVariables() that will set your variables to 0 or “ “.
Click the Call Symbol on the Left and Drag and Drop to the flow lines between Start and Stop.
Double click on the Call Symbol and type the name of your first module. For example, type
declareVariables in the Enter Call box. Do not put the ( ) when using Raptor. Click the Done

Step 2: Continue this process to add your additional methods, which are inputData(),
calcCosts(), and displayBill(). Main should look like this:
In Raptor
In Visio
Start
End
declareVariables()
inputData()
calcCosts()
displayBill()
Step 3: Click on the inputData module and add the necessary code to input clientName and
feetUTP. Watch the Help Video 4-2 to see how to input variables in Raptor and Visio.
Step 4: Click the calcCosts module and add the necessary code to compute calculations. Watch
the Help Video 4-2 to see how to add calculations in Raptor and Visio.
Step 5: Click the displayBill module and add the necessary code to display the clientName and
totalCost to the screen. Watch the Help Video 4-2 to see how to display variables in Raptor and

This document provides an overview of different types of PeopleCode events in PeopleSoft applications. It discusses page events like Activate and component events like FieldChange, RowInsert, and SaveEdit. Each event is described in 1-2 sentences explaining what it is and when it fires. The document also notes what types of objects (pages, fields, etc.) each event can be associated with.

4. Chapter 8: Using Procedures and Exception Handling 4 Introduction As an application grows, it is important to divide each facet of a problem into separate sections of code called procedures Try-Catch blocks can check for any error a user might commit One way to make your programs more professional is to display a splash screen while the full program loads

9. Chapter 8: Using Procedures and Exception Handling 9 Pausing the Splash Screen After the splash screen loads, the application executes any code in the form load event handler. To display the splash screen for five seconds, the code that calls the Sleep procedure should be in the form load event handler. To open the code editor window and the form load event handler, double-click the background of the frmTours Windows Form object in the Design window Click inside the frmToursLoad event handler. Type Threading. To cause IntelliSense to display a list of possible entries. If necessary, type T to select Thread from the IntelliSense list. Type .S to select Sleep from the IntelliSense list.

16. Chapter 8: Using Procedures and Exception Handling 16 Coding a Sub Procedure When a program is broken into manageable parts, each part is called a procedure A procedure is a named set of code that performs a given task A Sub procedure is a procedure that completes its task but does not return any data to the calling procedure A Sub procedure is the series of Visual Basic statements enclosed by the Sub and End Sub statements A Sub procedure is called with a statement consisting of the procedure name and a set of parentheses in the form of a procedure call

20. Chapter 8: Using Procedures and Exception Handling 20 Passing Arguments by Value (ByVal) When a procedure is called, the call statement can pass an argument to the called procedure The value is copied into a variable whose name is specified in the Sub procedure declaration statement

22. Chapter 8: Using Procedures and Exception Handling 22 Passing Arguments by Value (ByVal)
23. Chapter 8: Using Procedures and Exception Handling 23 Passing Arguments by Reference The second way in which to pass an argument from a calling procedure to a called Sub procedure is by reference You specify you want to pass a value by reference by entering the keyword ByRef in the Sub procedure declaration Passing a value by reference allows code in the Sub procedure to modify the contents of the variable that is being passed because when you use ByRef, you are passing a reference to the variable that holds the value instead of the value as when you use ByVal
24. Chapter 8: Using Procedures and Exception Handling 24 Passing Arguments by Reference
25. Chapter 8: Using Procedures and Exception Handling 25 Passing Arguments by Reference
26. Chapter 8: Using Procedures and Exception Handling 26 Passing Multiple Arguments You can pass as many arguments as needed to a Sub procedure If you have more than one argument, the variables are passed in the same order in which they appear in the procedure call statement
27. Chapter 8: Using Procedures and Exception Handling 27 Function Procedures A Function procedure is similar to a Sub procedure except that a Function procedure returns a single value to the calling procedure
28. Chapter 8: Using Procedures and Exception Handling 28 Function Procedures The Function procedure is different in appearance from a Sub procedure in the following ways: The Function procedure call has a receiving variable that is assigned the returned value from the Function procedure The data type of the return value is listed in the procedure declaration The keyword Return is used in the Function procedure to return a single value

Procedures should: Perform a single task Perform reasonably substantial processing Use Sub and Function procedures appropriately
