umm... im using &, and ~= and their working just fine in my code...
and they are used in the default code from I.F.

~= is not valid syntax. The editor complains about it and won't even tokenize. It also is not any of the four default codes, so I'm not sure where you saw it. As for &, it is not the correct operator to use here. Here's a quote straight from the Stamp Manual (page 153):

The easiest way to avoid the kinds of problems this might cause is to always use a conditional operator with IF...THEN. Change the example above to read IF Flag = 1 THEN IsTrue. The result of the comparison will follow IF...THEN rules. Also, the logical operators will work as they should; IF NOT Flag = 1 THEN IsTrue will correctly evaluate to false when Flag contains 1.
This also means that you should only use the "named" conditional logic operators NOT, AND, OR, and XOR with IF...THEN. The conditional logic operators format their results correctly for IF...THEN instructions. The other logical operators, represented by symbols ~ & | and ^ do not; they are binary logic operators.

Finally, see any of the below threads for more info:
