HPs, How type this.
Hi all,

Newbe with HP35s, I wonder how type this kind of instructions :

for example :

Q002 SQ(REGY)-4*REGZ*REGX
Q011 -REGY/REGZ/2
Q017 2 REAL ROOTS CK=9C4D LN=12
Q018 PSE
Q019 CF 10
Q020 (-REGY+SQRT(REGX))/REGZ/2 CK=2A08 LN=25
Q021 (-REGZ-SQRT(REGY))/REGT/2 CK=E499 LN=25
Q022 RTN
Q023 SF 10
Q024 2 CPLX ROOTS
Q025 PSE
Q026 CF 10
Q027 (-REGY+SQRT(-REGX)*i)/REGZ/2 CK=1DFA LN=28
Q028 (-REGZ-SQRT(-REGY)*i)/REGT/2 CK=D662 LN=28

May be one could explain me.
Thank's in advance.

Gérard.

REGX/REGY/REGZ/REGT are used to access the 4 stack registers.

From the manual, Page B-7:

"To use these instructions, press [EQN] first. Then, pressing [Rv] produces a menu in
the display showing the X–, Y–, Z–, T–registers. Pressing [>] or [<] will move the
underline symbol, indicating which register is presently selected. Pressing [Enter]
will place an instruction into a program or equation that recalls the value of the
chosen stack register for further use. These are displayed as REGX, REGY, REGZ,
and REGT."

[Rv] is the roll down key.

If you don't have it, I'm sure the manual is available on HP's website.

This machine is well-known to have lots of bugs, but they are mostly obscure and typically don't affect general use. It is a nice RPN machine to learn and use, despite the bugs. One bug that can affect all users is that the checksum shown for a program is not always correct, however you can confirm a program you've typed-in is the same as your source by comparing them line-by-line, just like we have always done with older machines.

No problem, glad to help.

It does seem morally wrong that HP included how to use Algebraic formulas in the main portion of the manual, but how to access the stack registers is stuck in an Appendix, so not easy to find...

Well done! The only official manual I can find for the HP 35s is in English.

EDIT: I just found this one in French: https://cdn-s1.lyreco.com/staticswebshop...207242.pdf
