(A2!=GLBV2)
Assign = Assigns one variable to another.
e.g.GLBV1=A1. (GLBV1 becomes the value of
A1).
Equal to == Returns a true or false result from testing if two
variables are equal to each other. e.g. IF
(A1==GLBV1)
Greater than > Returns a true or false result from testing if one
variable is greater than another
Greater than or equal to >= Returns a true or false result from testing if one
variable is greater or equal to than another
Less than < Returns a true or false result from testing if one
