question on 12c programming

[Don Shepherd]

On my gold 12c, if I include the instruction CLR sigma (to clear the statistics registers), the display is blank until the program ends, instead of displaying RUNNING. On the 12cp 25th anniversary edition, that doesn't happen, it works as normal. Someone told me about this a couple of years ago, and I appreciate that.

But why? Was this just a bug in the original 12c that they fixed in the platinum?

Platinum has different routines. It even computes a different interest rate.

Yes, the 12CP is a 12C simulator, whereas the new 12C is an emulator. BTW, the 12CP is faster and more accurate. This is illustrated a program I posted here: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv016.cgi?read=100275, message #6.
