NIL

The NIL is one of the 3 types of registers in the T21 - Basic Execution Node. To call it a register is a bit of a misnomer, but the documentation manual refers to it as such. The manual classifies it as a special internal type of register. it appears to actually be specialized microcode instruction that can be used to retrieve the value 0. it is currently unknown if this is faster or slower than invoking the literal value zero. Values can be discarded by moving them to the NIL register.
==Description==
Reading NIL produces the value zero. Writing to NIL has no effect. NIL can be used as a destination operand to execute an instruction for its side effects only, discarding the result.
