that makes sense. does the code look good as far as optimization and stuff as well so i can make optimization changes while i have it at this stage.

I see no major optimizations to be made to your code at this points. Looks pretty good in that department.

The code looks good overall, but I did notice some optimizations you can make.

Code:

:ClrHome
:ClrDraw
:AxesOff
:PlotsOff
:FnOff
:0→Xmin:1→ΔX
:-62→Ymin:1→ΔY
:Text(9,20,"SPREAD SHEET V1.0
:Text(18,42,"BY
:Text(27,30,"LAFFERJM
:Text(55,5,"C
:Circle(6,-58,4
:Text(55,12,"LAFFERJM
:Pause
:Repeat Ans=14
:ClrDraw
:DelVar [A]{8,7→dim([A]
:Text(0,20,"NEW
:Text(0,60,"QUIT
:Horizontal -6
:Line(0,-6,0,Ymin
:Line(Xmax,-6,Xmax,Ymin
:For(A,-6,Ymin,-7
:Horizontal A
:End
:For(A,13,78,13
:Line(A,-6,A,Ymin
:End

Assuming you just want to display the matrix value of [A](1,1 on each place on the screen, you can just use two nested For loops. For loops are a specialized form of a While loop, and they are faster than While/Repeat loops.

:For(D,2,88,13
:For(C,7,56,7
:Text(C,D,[A](1,1
:End
:End
:Repeat Ans
:getKey
:End
:End
:ClrDraw
:ClrHome
:ZStandard
:AxesOn
:DelVar [A]Disp "THANKS FOR
:Pause "USING.
:ClrHome:"
i tried with for loop it didnt go as fast as the repeat at least on my calc.

Are you sure? That definitely looks like it should go faster based on standard optimization rules for speed and size.
i am having some problems with the following code. i am using it so i can make a side scrolling type game but whenever b = 25 and a = 10 i get a dimension error. can someone tell me what could be causeing it because the string i use is 32 characters long.


Code:

:ClrHome
:"+-*/+-*/+-*/+-*/+-*/+-*/+-*/+-*/→Str1
:1→A
:16→B
:1→C
:Repeat K=45
:Output(7,C,"X
:Output(8,1,sub(Str1,A,B
:getKey→K
:If max(K=24,26
:Then
:Output(7,C,"
:C+(K=26)(C<16)-(K=24)(C>1→C
:B+(C=16)(K=26)(B<32)-(C=1)(K=24)(A>1→B
:B-15→A
:End
:End
:DelVar ADelVar BDelVar CDelVar KDelVar Str1ClrHome

Well, sub(Str1,10,25 on a 32 character string can be expected to throw an error. This situation is trying to return 25 characters from str1 starting at the tenth character, and there aren't enough characters. Remember, the syntax for sub( is

Code:

sub(string,start_position,number_characters)

oh well that makes sense. i thought it was


Code:

sub(start, end


thanks for the help
