Now you resort to moving the goalpost. I'm talking about the DSNZ instruction here, not the DSNE instruction, their uncle or any other relatives.

Can you post a simple example that shows the alleged "usefulness" and "cleanness" afforded by this DSNZ instruction, yes or no ?

And please, no "cumulative (lower tail) binomial distribution"-like programs, just something simple, on the level of a factorial program or something equally simple. Simple does it.

If you can't deliver what is asked, well, the world doesn't end but I'm not asking again, I'll simply rest my case that this DSNZ instruction is pretty dumb, as no simple proof-of-concept program can be produced to demonstrate its supposed virtues, period.

Again, thanks and regards.

The only reason I have DSNE there is because the 15C has DSE rather than DSZ, and that was the model I had handy to quickly knock this together. It would work exactly the same if you replace that instruction with DSNZ in the example - it's just counting down toward zero.

Please get over yourself, INV DSZ is no more stupid/redundant than including LOG when the calculator already has LN available.
