The first interesting thing to know is how to write comments.
In VB .NET, you write a comment by writing an apostrophe ' or writing
REM. This means the rest of the line will not be taken into account by the compiler.
'This entire line is a comment Dim x As Integer = 0 'This comment is here to say we give 0 value to x REM There are no such things as multiline comments 'So we have to start everyline with the apostrophe or REM
