A Logical Start

Before we can start talking about programming, we must understand a simple form of logic.

Everyone who has worked with logic knows that it simply starts with TRUE and FALSE.  When we program, each part of the program generates a result (TRUE) or fails (FALSE).  A sequence of statements or functions may work together and produce multiple results or failures at the same time.  It is for this reason that the standard logic table can direct your efforts in troubleshooting at later stages.  For your reference this table is included below:

Function	Values	TRUE	FALSE
NOT		FALSE	TRUE
AND	TRUE	TRUE	FALSE
	FALSE	FALSE	FALSE
OR	TRUE	TRUE	TRUE
	FALSE	TRUE	FALSE
XOR (Only one is TRUE)	TRUE	FALSE	TRUE
	FALSE	TRUE	FALSE
NOR (Neither is TRUE)	TRUE	FALSE	FALSE
	FALSE	FALSE	TRUE
