Here's another challenge:
create the smallest program that will display a graphical menu ( Using the graph with 'text(', not 'output(' ) with these functions:
- Title is "TEST" (Centered)
- must have these items (Exactly like they are, left align):
- can scroll up/down with a cursor (use '}' for the cursor)
- cursor should be able to wrap around (not just stop at top/bottom)
- can select by pressing the cooresponding number, or by pressing 2nd/enter (both of them)
- on A, displays "A", and quits
- Same for B except display "B"
- Same for C except display "C"
Here's an example program of what it should do (this is not the solution, I think)
The program doesn't have to clear the screen or turn axis off.
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Text(0,40,"TEST
Text(6,4,"1:A
Text(12,4,"2:B
Text(18,4,"3:C
6->A
lbl A
Text(A,0,"}
Getkey->B
Text(A,0,"4 spaces
A-6(B=25)+6(B=34)-18(A=1 +24(A=6->A
If B=92:Goto 0
If B=93:Goto 1
If B=94:Goto 2
If B!=21 or B!=105:Goto A
If A=6:Goto 0
If A=12:Goto 1
If A=18;Goto 2
Lbl 0
Disp "A
Stop
Lbl 1
Disp "B
Stop
Lbl 2
Disp "C
Stop
I hope this works, as I just typed it in and didn't try it out

| Since Stop is one token, isn't it one byte? |

| True, 'Stop' is one byte, but each newline is also a byte. |

you can also change all b's in this part
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"] A-6(B=25)+6(B=34)-18(A=1+24(A=6->A
to ans. |

| What good will that do? After you store to A, Ans will equal A, so you won't be able to test what it is later. They're both 1 byte anyways, so size of the variable doesn't matter. |

| first of all the getkey stores to b so you can test what it is later and second of all, ans is faster then b. |

there is a bug in it.
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]A-6(B=25)+6(B=34)-18(A=1+24(A=6->A
acording to me, this is supposed to be
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]A-6(ans+25)+6(ans=34)-18(A=1(ans=34)+18(A=6)(ans=25->A
and this is what I have (it works, I tested it)
[color=#000000background#000000]
Text(0,40,"TEST
Text(6,4,"1:A
Text(12,4,"2:B
Text(18,4,"3:C
6->A
repeat max(B={21,105,92,93,94
Text(A,0,"}
repeat ans
Getkey->B
end
Text(A,0," <<<4 spaces>>>
A-6(ans+25)+6(ans=34)-18(A=1(ans=34)+18(A=6)(ans=25->A
end
if A=6 or B=92:"A
if A=12 or B=93:"B

Didn't he say that was just an example?

So shouldn't we be worrying about writing one instead of fixing his example? |

The following, I think, is reasonably close to the ideal size.
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]1->S
Text(0,40,"TEST
Text(6,4,"1:A
Text(12,4,"2:B
Text(18,4,"3:C
Repeat max(K={21,92,93,94,105
Text(6S,0,"}
Repeat Ans
getKey->K
End
Text(6S,0," (3 spaces)
S+(Ans=34)-(Ans=25
Ans+3(not(Ans)-(Ans=3->S
End
If max(K={21,105
Then
S
Else
K-91
End
Disp sub("ABC",Ans,1
This isn't really an interesting challenge however, it gets too technical, and you're tempted to sacrifice quality for size.
Something that appeals more to the mathematician in me:
you're given six variables (something along the lines of [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Prompt A,B,C,D,E,F at the beginning) that represent the three sides and angles of a triangle. Some of them have zeroes instead of the value. Solve for the unknown sides/angles if possible. |

sorry for the typo :blush: , I fixed it.

I don't know if it is possible without knowing which variables are sides and which variables are angles.

| You would have them imput angles first then sides. or the other way around I guess. |

Some of them have zeroes instead of the value. Solve for the unknown sides/angles if possible. It took me a while, but here it is finally:
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Prompt A,B,C,D,E,F // Sides, angles
{A,B,C→L1
{D,E,F→L2

Degree
{1,2,3→L3
If min(L1+L2) and 1=sum(not(L1
Then
max(L3not(L1
√(sum(L1²)-2prod(L1+not(L1))cos(L2(Ans→L1(Ans
End
If 1=sum(not(L2
180-sum(L2→L2(max(L3not(L2
If min(L2) and 2=sum(not(L1
max(L1)sin(L2)/sin(L2(max(L3not(not(L1→L1
If max(L1L2) and 1=sum(not(L1)) and 2=sum(not(L2
Then
max(L2→θ
L1(sum(L2L3/Ans→Y
L1(sum((L1>L1L2)L3
cos(θ)Ans+{1,-1}√(Y²-Ans²sin(θ)²
(Ans>0)Ans→L2
End
sum(L3not(L1→X
For(Y,1,4-dim(L2)-(2=dim(L2))max(not(L2
If 2=dim(L2
L2(Y→L1(X
Pause L1
Pause cos‾¹(Ans/prod(Ans)(.5sum(Ans²)-Ans²
.5sum(L1
Pause √(Ansprod(Ans-L1
End
This gives:
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]{a,b,c} Sides
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]{A,B,C} Angles
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Area___ Area in units
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"][color=gray]{a,b,c} Sides on other possible triangle
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]{A,B,C} Angles on other possible triangle
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Area___ Area of other possible triangle[/color]
The program will halt immediately if the user doesn't provide exactly three zeros and three non-zero values.
The bottom three answers will only appear when the Side-Side-Angle theorem yields two possible triangles.

Very nice!  As usual, your optimization skills are superb.
Allow me optimize one byte: instead of
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"](Ans>0)Ans→L2,
how about
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Ans(Ans>0→L2.  |
