In Lite-C there is an operator to make decision about equality.
In this language, as like as all "C" like languages, this operator is the "==".
Sometime in programming we need to examine the reversed equality for this purpose is being the "|=".
So just imagine

• 1. == equal
• 2. |= not equal
• 3. >= greater than
• 4. <= less than

and so on...
