Executed if the IF-THEN expression is false.
You don't have to use the ELSE statement in an IF THEN .. END IF structure.
You can use the ELSEIF statement to test for another condition.
IF a = 1 THEN
ELSEIF a = 2 THEN
ELSEIF b1 > a THEN
Dim A As Byte
A = 10 'let a = 10
If A > 10 Then 'make a decision
Print "A >10" 'this will not be printed
Print "A not greater than 10" 'this will be printed
