1) in programming mode, in the FMEM option, it would be very nice to have the same softmenu as in the native CASIOBASIC:[STO] [RCL] [fn] [SEE], not just the single [fn] as in C.BASIC. Since any set of characters can be written in fn, it is sometimes convenient to use these fn as readymade templates when writing various repetitive constructs using the [SEE] and [RCL] commands.
2) the commands fn and Str_ behave similarly in most cases. Example:
?➝Str 1:?➝fn1:Str 1➝fn3 Disp Str 1:Disp fn1 Disp Str 1+fn1:Disp Exp(Str 1+fn1)Could you add commands like fn1➝Str 1 and fn1+Str 3➝Str 1 so that they don`t produce Syntax ERROR?
3) working with flags. In my opinion, these features are needed in C.BASIC. Even in such simple calculators as TI83plus, these functions have been added to some libraries and programs. It turned out no worse than in HP calculators. The BatLib app for TI83 has the dim(33 (FlagWrite) command. For example, dim(33,69,4) means: in group number 4 (graph settings), set the Dot, Sequential, GridOn, Rectangular, CoordOn, AxisOn, and LabelOn flags.
That is, d69=b1000101, and each of the seven positions in the binary number is responsible for the state of a particular flag in the group. It`s a bit complicated, but very effective. In C. BASIC, I suggest relevance at least two system variables StoFlags and RclFlags to quickly return to the original settings after changing them in some program.
4) suppose the program requests Input data?. I must enter either a vector [[1,2,3]] or a list {5,6,7} or a function a×x^2+b×x or a matrix or text. How can the program save the entered information correctly? It seems to me that in C.BASIC it is necessary to have one universal variable (UVar) for such cases. Pseudocode:
"Input data"?➝UVar:UVarType➝T ....... ....... If T=2:Then UVar➝_abc ........ ...... If T=5:Then UVar➝List 1 If T=8:Then UVar➝Str 1 ....... ....... If T=0:Then UVar➝Str 1 //an undefined type or incorrect syntax ×+÷cos(ABC}} is treated as a String type

1) I see, in C.BASIC fn and Y functions evaluate in algebraic expressions, but in Disp and Locate output they behave as String variables and don`t evaluate unlike in genuine BASIC. It seems to me that they should evaluate everyplace as in genuine BASIC without additional command Exp(, because that is their main difference from String. Only in this case, the absence of the fn➝Str N command is quite logical, in my opinion.
2) Please, add [Y] [r] [Xt] [Yt] x to the VARS/GRPH menu option, if possible.
3) I checked the text LCD output speed in RefrshCtl DD:off and RefrshCtl DD:Grph 5/128 mode.
ClrText For 1➝K To 50 Step 1 "1:ABCDEFGHIJKLMNOPQR" "2:ABCDEFGHIJKLMNOPQR" "3:ABCDEFGHIJKLMNOPQR" "4:ABCDEFGHIJKLMNOPQR" "5:ABCDEFGHIJKLMNOPQR" "6:ABCDEFGHIJKLMNOPQR" ClrText "7:STUVWYZABCDEFGHIJK" "8:STUVWYZABCDEFGHIJK" "9:STUVWYZABCDEFGHIJK" "10:STUVWYZABCDEFGHIJ" "11:STUVWYZABCDEFGHIJ" "12:STUVWYZABCDEFGHIJ" NextThe speed in C.BASIC was three times slower than in native BASIC. In RefrshCtl DD:All 5/128 mode, text output works fine, i.e. much faster than in genuine BASIC. What is the meaning of RefrshCtl DD:off mode?

"RefrshCtl DD:off" is always transfers to the LCD at the end of the command.

Hi, Sentaro! Many thanks for the continuous improvement of CBASIC. The CASIOs now looks like a real math pocket computers. I have one small question: is it possible to implement the numtostring function? This is really necessary in some programs. In ti83_plus, for example, this is partially implemented in the OS with the LinReg(a+bx) command: LinReg(a+bx)_L1, L2, Y1: Equ►String(Y1, str1). In CASIO there is not ability to write system variables a,b to string or function as a numeric result. In ti83 I can write this HEXcode directly on the calculator, like:

Right. It because you send it to “计算器吧”, but this “吧” is not popular than “fxes(ms)吧”.

It's a very difficult job to implement each new feature. Thanks again for STO/RCL/fn/SEE. As for DispFTbl, I didn't mean for CBASIC to fully copy from genuineBASIC. All we need to do is calculate the parameters and create the matrixAns variable (i.e. DispFTbl) as a readymade table of results stored to matrix type.

Angle:_Rad
Setup Recover:_on Max Mem Mode:_off
Use Hidn RAM:_on Hidn RAM Init:_on
Max List 52×1:_(52) Exec Time Dsp:_on
Mat Dsp:_m,n Storage mode:_S.Mem
Refrsh Ctl DD:_All 5/128 Execute mode:_DBL#
In V2, after running the program, the cursor is placed at the end of the text (in edit mode). In V1 the cursor does not change position after the program is executed, and this is much more convenient for multiple edits of the text, when you do not have to search for the old place each time to correct.
In V2, when viewing the CPLX matrix, scrolling is 20% slower than in the V1.
In both versions:
 the ClrMat_ command deletes all Lists in addition to Matrices;
 If you set Max Mem mode:_on, then the message File Reading..... always starts appearing even if you exit from text viewing mode without any editing. I don`t know if this is right.
In the V2 the speed of performing certain operations is noticeably reduced compared to the V1.
Below I give the results in DBL# mode as the number of operations per second
for different commands. In tests, I used 500row×1col lists, 500row×3col matrices,
and the expression
2×sin ((A+B)÷2)×cos ((AB)÷2),
written in the functions Y5 and fn5.
1) List_2[K]➝List_3[K]8500 times per sec.(V1)/8200 times per sec.(V2)
2) Mat_A[K,2]➝Mat_A[K,3] 11100/10400
3) Y5➝R1200/570 times per second
calculates the expr.
2×sin ((A+B)÷2)×cos ((AB)÷2). Amazingly!
4) 2×sin ((A+B)÷2)×cos ((AB)÷2)➝R 880/750At this point,
what is very strange is that the direct calculation of an expression
in v2.44build6 is much slower than the calculation via the "Y" function, (1200 vs 880).
5) fn5(K)➝R 780/680 6) For ... Next 37000/33500 7) Y5(K)➝R 1125/625 8) S+1÷K➝S 3500/3500That`s all I noticed. In other modes and functions, the speed discrepancy is minimal, so I don`t give all the results.

Thank you for the hint regarding binary calculations. I tested this method in versions v2. 44/6 and v2. 45/15 on the 9860gii2 calculator and measured the calculation speed in a loop for different expressions:
1) expression➝R
2) Y5➝R
3) Y5(K)➝R
4) fn5➝R
5) fn5(K)➝R
Also, I wrote the expression in functions in two ways
(expr) and (expr))
and received five different results in twenty experiments (5 examples × 2 variants × 2 versions):
a) (  ) slowdown 5...25% b) (++) speedup 25...45% c) (  )) slowdown 5% d) ( ++ )) speedup 0...45% e) (...)) syntax errorFunctions like Y in v2. 44/6 are set to maximum speed by default, and adding extra brackets to the expression slows down calculations.
In v2. 45/15, in functions 3) and 5), ( # # # ) gives the minimum speed, and ( # # # )) gives the maximum speed.I hope this information can be useful.

If you don`t mind, could you create a benchmark program?
It`s an interesting thought! The test program will greatly simplify the verification and comparison procedure. As source constants, we could take the best results from the last two versions, for example, and output relative changes of ± % in any other version, as well as absolute speed values. I will try to write a test at the end of the week.

@Sentaro
I have a few questions about v2. 45.
1) When working with multiple matrices in program, they sometimes change the specification (m,n)↔(x,y). Columns and rows are swapped, which causes a Dimension ERROR message or an incorrect result.
2) When accessing subroutines like
Gosub X, P, T, 2, Y: ... Lbl X: Local a, b, c, d: ... writing local parameters is often ignored, leaving them equal to zero.
3) After handling with arrays in program, the list of variables displays Lst θ [byte] or Mat θ [byte] size of 2×256. Is this a mistake, or should it be?
4) The List_1+i×List_2➝List_5 operation is not working. `#CBcplx:10➝DimList_5 (for example) doesn`t help. But creating an array in the loop :For ... List_1[K]+i×List_2[K]➝List_5[K] ... Next: works well.
5) Seq(X,X,1,3,0.02) or Seq(X,X,1,1.2,0.05) operation loses the last element of the array, stopping at the value 2.95 or 1.15. This is probably due to rounding a number in the binary representation?
6)
(2^32)+2×(2^15) ➝Ticks% While Ticks%<(2^15):WhileEnd Disp Ticks%The answer is 32720, Execute Time = 1.0219 s.
When storing, Ticks% change the sign of the argument, but returns the argument without changing the sign.
So, (2^32)+2×2^15 = (2×2^15)?
In the benchmark, I decided to make several pages of 8 points (tests) each. The main menu allows you to scroll through pages bу▼◄ ► buttons and quickly evaluate the results
For detailed information, we can select an item using the ... keys and scroll through the items in the information list. The tests are compared with benchmarks that we use as constants. "1.25 " means 1.25 times slower, "1.51 +" means 1.51 times faster.
The last couple of pages I plan to use to check standard algorithms for errors in a particular version. I think this approach will make it easier to learn C.Basic.
