An now you've lost your result. I assume you want to add X to Y. Or then subtract X from Y.

In my system 'lift' and 'drop' do not include the accumulator X. In other words, X never drops away... T drops into Z, Z drops into Y, X is left alone.

Also, auto 'lift' is a state which is 'on' by default and must be explicitly 'silenced' or turned 'off'. There are times when the user will want to turn of auto 'lift' and enter into X leaving the Y,Z, & T regs alone. There are other times when the user will want the stack to 'lift' -- that is X replicates into Y, Y into Z, Z into T, and T into oblivion. Auto 'lift' should be configurable on|off and it should have a [key] to toggle it on|off as well.


The entire system should be 'explicit' and the entire system should be fully integrated... that is, the entire system (all op codes) should have ONE consistent interface to the stack... NO SPECIAL CASES or HIDDEN POLICIES. NO EXCEPTIONS.
