Logical operators and IF statement

[rcaffin]

I know there are some ways to implement a NOT operator and an EQ (or NEQ) operator, but they are messy.
Could we please have explicit NOT(x), a.EQ.b, a.NEQ.b operators? They would be very easy to do.
While I am at it ... in addition to .EQ., how about .GT. and .GE. (etc)?

And PLEASE, could we have an explicit IF THEN ELSE statement? Yes, the effect can be done with macros, but that is obscure and clumsy. Clarity in code is very desirable.

Adding the Conditional could transform the way we write g-code for industrial use. Please?

Cheers
