This assumes you enter the following keystrokes to solve the problem
100000.00001 STO 01
CLx
D

This takes time though!

(please excuse if I overlooked the stack lift, but I think it preserves the stack)[/code]

The original HP-15C program assumes n on register X, no previous initialization:

100000 GSB A --> 5000050000

Anyway, your program would return 5000150000, which is off by 100000. But of course it can be improved. Since the increment is 1 the fractional part is optional, thus saving the IP instruction. Also, you can use BACK nnn to save occasional LBLs steps in the middle of the program.
