RPN program notes:
We’ll key the income into the display before running the
program so that it will be in the X-register when the
0 instruction in program
line 001 is executed. This instruction will place the test value 20,000 in the
X-register and (as explained in Appendix A) move the income into the Y-register.
instruction in program line 002 will exchange the numbers in the X- and
Y-registers (as also explained in Appendix A): that is, it will place the income back
into the X-register and place the test value into the Y-register. This is necessary
because when either the
2 instruction in line 005 or the
1 instruction in
line 007 is executed, the number in the X-register is moved into the Y-register; if the
instruction were not included, the test value 20,000, rather than the income,
would be in the Y-register when the
instruction in line 008 is executed.
