10.6 Logical Operators
The logical operators available in EBLWin are in the following priority order:
( ) parentheses, changes priority order
NOT not-function (inverts), is written NOT in EBLWin
AND and-function, is written AND in EBLWin
OR or-function, is written OR in EBLWin
10.6.1 Control Expression Examples
In order to understand how to create control expressions, here follow some AND, OR, NOT
and ( ) examples and also some control expression examples.
10.6.1.1 AND
a AND b AND c=y
y is true (=1) when all the conditions a, b, c are true, i.e. a=1 and b=1
and c=1 makes y=1. All other combinations makes y=0.
This is also shown in the truth table:
10.6.1.2 OR
a OR b OR c=y
y is true if at least one of the conditions a, b, c is true, i.e. a=1 or b=1
or c=1 makes y=1.
This is also shown in the truth table:
10.6.1.3 NOT
Inverts a condition, e.g. NOT b = NOT 0 = 1.
A OR NOT b AND c =y
This is shown in the truth table:
