By the end of this video you should:

• Deepen your appreciation for how modularity helps us combat complexity
• Be able to use subs and functions to modularize your programs, i.e. you should:
  • Know the types of subs and functions
  • Know how to identify the code to be modularized
  • Know how to write both subs and function, with
    • An appropriate access modifier
    • An appropriate name, using naming conventions
    • Parameters passed correctly, i.e. ByVal vs. ByRef
    • A correctly typed return value if necessary
  • Know when to choose a sub vs. a function

Click for screenshot of how to access the ISAT 252 FTP server

If you are using windows you can just type ftp://dev.isat.jmu.edu into the address bar of any folder or explorer window.  When prompted your username is your eID and your password is one that will have been sent to you via email.

If you are using another FTP client, here is the information you’ll need to access the server:

• Hostname: dev.isat.jmu.edu
• Username: your eID
• Password: being sent to you via email

If you have problems please let me know.

In this video we’ll use the MMLogic tool to deepen our understanding of how computers “think” by creating a full adder.
