Hi,

Yes, QPI without the arrow on the left, it is faster to type.

Until it's officially renamed, create your own alias for →Qπ called "qpi". It's not only easier to type but it also works in CAS:

Thanks for the tip. I called it "CantorTurningInHisGrave" ;-)

Hi Joe,

Thanks for this tips.

But be aware that a soft reset with <On-Symb> will mess up the "defines" (input variables will become unchecked), and sometimes the entire "define" function will even disappear. Until this is fixed, I prefer to have qpi as a one-line program in the catalog.

The entire function will only disappear if you haven't turned the calculator off and back on between creating the definition and pressing On+Symb. Toggling power saves Prime's RAM (where Defines reside) to flash, so it's always a good idea to do that right after doing anything that you don't want to lose (e.g. a Define).

One could also make a program to create user defined functions:

HVars("qpi",{"X"}):='→Qπ(X)'

Yes - - this approach (via HVars) seems to hold everything together, even after a soft reset.
