Example 2:
With the two programs now stored in program memory from the
preceding examples (occupying 27 program lines), store the amortization program
from Section 9(page 103). 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 02.
Since the
:
0 instruction is now in line 29, we’ll specify that line number with the
i
instruction in line 34.
