This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Note that a semi-colon by itself is an empty statement. So line 11 of your code means "if command equals "Map", then do nothing" - and the block in lines 12 - 18 is completely separate from the if-statement and is always executed.
