Inputting mixed numbers on HP50g

[bootlegend]

Right now I'm getting used to the entering all three portions with a space between each mentioned above. Then I hit / then + to get the mixed number in the stack. It's nearly as quick, but I think there is a mental pause for me personally. Maybe it's just the years of using the 35s, but inputting a mixed number required no "thought" on the 35s. 7 13/16 ths? 7.13.16 <enter>

I have never programmed anything on either calculator. Don't you have to call a program up? That seems cumbersome.

The possibility of using a double decimal between each portion of a mixed number sounds promising, but how would you implement that?
