Hello, Thierry;
the problems are simple, so far. To change comma (virgule) for period (dot), do the following:
1 - make sure the calculator is turned to OFF (hors-fonction);
2 - press and hold down the [.] key;
3 - while [.] is held down, switch the calculator ON;
4 - release [.] key
You can perform this set of operations for as many times as you need. They will toggle comma to dot everytime you press the keys in sequence.
About the [Error 3 ] message, you can choose a few options. Before that, find the [RCL] key and you'll see [MEM] printed in blue in one of its faces. Now, with the calculator switched to ON, please, follow this sequence:
1 - press the blue [g] key and release it;
2 - press and hold the [RCL] key (you performed [g][MEM]);
You'll see something like this:
[ 1 fr pr-b ]
where:
1 - number of the highest available register; as you cannot access any register above R1, you'll see '1'; this value may reach 65 and is named registers' segment, sort of a memory "share" to hold the numbered registers (*)
fr - number of free (available) registers in the "common segment', i.e., part of the existing memroy that can be occupied with program steps, matrix elements, complex stack and SOLVE/Integrate temporary scratch area
pr - number of hole registers currently used by program(s)
b - remaining bytes from last "assigned" register for program steps storage. b can be in the range 0 to 6
(*) except for registers RI, R0 and R1 that are permanently available
fr, pr and b vary in accordance with memory use register
The HP15C user can manualy specify the first parameter (that we assumed 1 in your case) by using the sequence [f][DIM][(i)] like this:
-enter the number of the highest register you plan to use (not the number of registers you plan to use);
- press [f][DIM][(i)]
Now you can check memory again and you'll see:
[g][MEM] (hold [MEM]-key pressed for as long as you ned to see)
[rr fr pr-b]
where rr is the number of the last available register. Remember that you will not be able to specify rr for a value bigger than the existing memory.
The other choice is memory clear [ Pr Error ]. Consider doing this only as a last alternative. If you want to perform this "master clear", do it:
1 - make sure the calculator is turned to OFF (ors-fonccion);
2 - press and hold down the [-] key;
3 - while [-] is held down, switch the calculator ON;
4 - release [-] key
You'll see [ Pr Error ], and if you press [g][MEM] right after clearing all memory, you'll see:
[ 19 46 0-0]
What means you may use any register from R0 to R9 and R.0 to R.9 and the index register RI
Hope this helps for now. If not, let us know.
