I wanted to know if it was possible to de-allocate VAR0 rather than just clear it?

That's the same procedure: clearing the highest-numbered variable deallocates it. So if var(1) to var(nnn) have been cleared by CLVARX 000, storing zero into var(0) also clears and thus deallocates var(0). Try it! Checking MEM will display VAR 0 afterwards.

Oh my Gosh, indeed!
And putting zero is the last variable systematically de-allocates it.
So you never can store zero in the last element of an array because when you recall it you have the message "INVALID (I)". What the heck is this logic!?
