Here is a version that adds some benefits:

• Mode settings (register d) are preserved.
• Output can be displayed as a mixed number or improper fraction.
  Clear resp. set flag 01.
• Denominator can be minimized or fixed.
  Clear resp. set flag 02.
• Input can be positive or negative.
• Integer output is displayed without "0/1" part.
  

Wow, this is really nice! I have not been able to find any errors in testing. I did make one small change. So as not to display the sign twice for negative output expressed as mixed numbers (this is just a personal preference), I replaced lines 50 and 51 with:

Code:

50 FC? 05
51 GTO 06
52 FS? 01
53 CHS
54 LBL 06

I appreciate the work you put into this, and I will definitely get daily use out of it. You should create an article in the 41C software library section once you're happy with the program.
