===== HAS NOT BIT ✓ =====

===== SYNTAX =====
     = value HAS NOT BIT position

==== PURPOSE ====

Think of a number as a sequence of switches, each of which can be on (1) or off (0). 
Each switch represents a bit. The ''HAS NOT BIT'' instruction will check
a bit off (0), by checking the state of a specific switch within this sequence.
The parameter ''position'' refers to the bit position inside the data. This value
is zero based, and starts from the less significative bit and go on.



==== EXAMPLE ====
    IF x HAS NOT BIT 2 THEN: PRINT "bit 2 is 0": ENDIF
