Plus42 Equations, Preview Release

[Vincent Weber]

Yes, all this is a bit tricky. I wrote a cash flow equation for Plus42, and what I did was to isolate the initial cash flow in a CF0 variable, separate from the cash flow list. Which is also good because the first cash flow doesn't have a #TIMES, this is usually the investment put at the beginning of a project.... The 17B has the UI to prompt the first cash flow (index 0) without a #T, and to prompt all the others with a #TIMES. Not too sure what is the best way to ensure compatibility, I think a slight mofication is acceptable here, since Plus42 has matrices....

HP started this mess with the 42S, as Thomas pointed out: REGOO is REGS[1], not REGS[0] !
