Did I find a bug or bug found me?

</i></font>A <font color="#000080"><b>VAR BYTE
</b></font>B <font color="#000080"><b>VAR BYTE
</b></font>C <font color="#000080"><b>VAR BYTE
</b></font>D <font color="#000080"><b>VAR BYTE

</b></font>A = <font color="#FF0000">100
</font>B = <font color="#FF0000">100
</font>C = <font color="#FF0000">100
</font>D = <font color="#FF0000">100


</font>Loop:

    <font color="#000080"><b>IF </b></font>A = B = C = D = <font color="#FF0000">100 </font><font color="#000080"><b>THEN </b></font>Loop
    
<font color="#000080"><b>GOTO </b></font>Loop

This code compiles with no error; but in practice, it does not come out true.


Am I going to learn something new now?
