[HP 35s] Hosoda's trig program affected by bug 20?

If that's the only reason that the solver fails then you could use a loop-unrolling:

Code:

J004 X<> 00
J005 ABS
J006 RCL 03
J007 RCL 02
J008 RCL 01
J009 RCL 00
J010 RTN

Code:

J015 RPN
J016 STO 00
J017 R↓
J018 STO 01
J019 R↓
J020 STO 02
J021 R↓
J022 STO 03
J023 R↓

I must admit that I don't understand the following lines:

Code:

J018 4
J019 STO I
J020 STO(I)
J021 DSE I

Why do we need the value 4 in register 04?

But I've noticed this line:

Code:

J066 ISG J

This might still lead to a problem when using the solver.

Kind regards
