Notes:

• Visual Basic is NOT a case-sensitive language!
• Strings and Variables
• Numeric Data Types Integer/Double/Boolean
• Variable Name (no quotes) - e.g. a bucket/container
• String Literal (with quotes) - e.g. the content itself
• Explicit (programmer code) and implicit (handled by VB) data type conversions.
• Best practice is to do the conversion yourself (explicit).
  
• Parse
  
• Expressions vs Statements - "Expressions can be Evaluated... Statements can be executed."
