Inputting mixed numbers on HP50g

[dizzy]

Perhaps you could use something like this (needs more work, and probably breaks some stuff; in particular, you can't enter multiple numbers/objects with this enabled):

Code:

\<<
IFERR
  STR\->
THEN
  IF
    ERRN #106h ==
  THEN
    Chars DUP
    "." ElemIndex
    "+" PUT
    DUP
    "." ElemIndex
    "/" PUT
    "'" SWAP + "'" +
    Strcat OBJ\->
  END
END
\>>
'\GaENTER' STO

Then switch on the user keyboard:

Code:

-62 SF
-63 SF

The above code requires GoferLists.
