In a recent Post #7 I noticed the following difference between these two models:

HP-15C

Code:

   001 { 42 21 11 } f LBL A
   002 {    22 11 } GTO A

HP-16C

Code:

   001 { 43 22  A } g LBL A
   002 {    22  A } GTO A

I had to double check with an emulator, but I've never noticed before that the HP-16C uses alphanumeric labels like A whereas both the HP-11C and HP-15C use the coordinates of keys like 11.
And both the HP-10C and HP-12C don't support labels at all.
