Example 2:
 With the two programs now stored in program memory from the 
preceding examples (occupying 27 program lines in RPN mode and 33 lines in 
ALG mode), store the amortization program from Section 9(page 125). Since there 
are already two programs stored in program memory, we’ll skip step 3 in the 
procedure above. Furthermore, since the amortization program ends with a loop, 
we’ll skip steps 5 and 6. When the amortization program was stored at the 
beginning of program memory, the 
i
 instruction at the end of the program 
branched to the 
:
0 instruction in line 002. In the RPN program, since the 
:
0 
instruction is now in line 029, we’ll specify that line number with the 
i
 
instruction in line 034. In the ALG program, since the 
:
0 instruction is now in 
line 035, we’ll specify that line number with the 
i
 instruction in line 041.
