Reinventing the TVM wheel

[Ángel Martin]

I admit that it got me worried but finally the issue is resolved - it turns out I had made a silly *mistake* in the formulas for the derivatives (shame, shame...). Once that was corrected I got the full suite to work in glorious MCODE; hah, the sweet taste of success...

I've tried the few examples from the 15C advanced functions manual as well as the tricky one form the forum posts - with correct results as expected. However it'll be good to test it more, anyone interested?

I cannot post the blueprint (ran out of allotted space it appears) until I delete previous attachments from other posts - so I posted the MOD file in a ZIP container... send me an email if you're up for it.

Thanks to all for your replies and Sylvain for sending the docs in the mail.

PS. Don't sell your HP-12C just yet - found one instance returning wrong results, will work on it soon.

To be continued...
