i need to know whats wrong with this code:
Code:
Lbl eqocir
ClrIO
Input "X1=",a
Input "Y1=",b
Input "X2=",c
Input "Y2=",d
Input "X3=",e
Input "Y3=",f
{a,c,e}»l1
{b,d,f}»l2
SortA l1,l2
l2[2]-l2[1]»g
l1[2]-l1[1]»h
If h=0 Then
0»i
Goto part3
Else
g/h»i
EndIf
If i=0 Then
{0}»l4:2»p:Goto part3
Else
0»p
ªi^(ª1)»i
Goto part3
EndIf
Lbl part3
(l2[2]+l2[1])/2»j
(l1[2]+l1[1])/2»k
j-i*k»l
{ªi}»l3
If p=2 Then
{k}»l5:Goto part4
Else
{l}»l5:Goto part4
EndIf
Lbl part4
l2[3]-l2[1]»g
l1[3]-l1[1]»h
If h=0 Then
0»i:Goto part5
Else
g/h»i
EndIf
If i=0 Then
1»p:Goto part5
Else
ªi^(ª1)»i
Goto part5
EndIf
Lbl part5
(l2[3]+l2[1])/2»j
(l1[3]+l1[1])/2»k
j-i*k»l
If p=1 Then
{l4[1],0}»l4
{l3[1],1}»l3
Goto part6
Else
{l4[1],1}»l4
{l3[1],ªi}»l3
Goto part6
EndIf
Lbl part6
If p=1 Then
{l5[1],k}»l5
Goto part7
Else
{l5[1],l}»l5
Goto part7
Lbl part7
listÐmat(l3)
listÐmat(l4)
listÐmat(l5)
l3*l4»l6
l6^(ª1)*l5»m1
matÐlist(m1)
m1[1]»m
m1[2]»n
(l1[3]-m)^2+(l2[3]-n)^2»o
ClrIO
Disp "H=",m
Disp "K=",n
Disp "R®=",o
Pause
EndIf
Goto end
i get a circular definition error no matter what number i put in. someone please tell me what im doing wrong!!! :confused:
the error occurs here:
Code:
{l4[1],1}»l4
{l3[1],ªi}»l3
Goto part6
EndIf
Lbl part6
If p=1 Then
{l5[1],k}»l5
Goto part7
Else
{l5[1],l}»l5
Goto part7
Lbl part7
listÐmat(l3)
listÐmat(l4)
listÐmat(l5)
l3*l4»l6
l6^(ª1)*l5»m1
matÐlist(m1)
m1[1]»m
m1[2]»n
(l1[3]-m)^2+(l2[3]-n)^2»o
ClrIO
Disp "H=",m
Disp "K=",n
Disp "R®=",o
Pause
EndIf
Goto end
is it that i cant put list4 item 1 into list4 on the 89? :confused:

As much as I'd like to help, I can't say that I'm familiar with this dialect
of TI-Basic. It's something we haven't seen for a while in these forums.
All I can provide is this: At some point you are trying to assign one variable to itself, and the recursion that results is the issue. See if this happens at one of the places where you work with lists 3 and 4. This is me out on a limb—I have no knowledge that it will work.

There are several problems in that code, which may or may not be what your error is.
1. before you goto part3, in some branches of the code you don't initialize p. Same thing before lbl part5.
2. You're jumping from the Then part of an If statement into the Else part. This may not be causing the error, but isn't a good idea in general.
3. list>mat(L3) and similar statements have no effect by themselves like that. They return a matrix, so you can say "list>mat(L3) -> M3" but as it is the code won't do anything.
4. Not only that, but m1 is not a matrix as you define it in your code. You stored a number to it. So mat>list(m1) will cause an error.
5. In general, the way you use Gotos and Labels is ineffective. For example, the following bits of code do the same thing:
Code:
If foo=1 Then
...
Goto bar
Else
...
Goto bar
EndIf
Lbl bar
Code:
If foo=1 Then
...
Else
...
EndIf
In fact, you can get rid of all of the gotos and labels in that program. |

i have changed the code removing all the labels and gotos (except the first and last because this is just a section of a larger program):
Code:
Lbl eqocir
ClrIO
Input "X1: ",a
Input "Y1: ",b
Input "X2: ",c
Input "Y2: ",d
Input "X3: ",e
Input "Y3: ",f
{a,c,e}»l1
{b,d,f}»l2
SortA l1,l2
l2[2]-l2[1]»g
l1[2]-l1[1]»h
If h=0 Then
0»i
Else
g/h»i
EndIf
If i=0 Then
{0}»l4:2»p
Else
0»p
ªi^(ª1)»i
EndIf
(l2[2]+l2[1])/2»j
(l1[2]+l1[1])/2»k
j-i*k»l
{ªi}»l3
If p=2 Then
{k}»l5
Else
{l}»l5
EndIf
l2[3]-l2[1]»g
l1[3]-l1[1]»h
If h=0 Then
0»i
Else
g/h»i
EndIf
If i=0 Then
1»p
Else
ªi^(ª1)»i
EndIf
(l2[3]+l2[1])/2»j
(l1[3]+l1[1])/2»k
j-i*k»l
If p=1 Then
{l4[1],0}»l4
{l3[1],1}»l3
Else
{l4[1],1}»l4
{l3[1],ªi}»l3
EndIf
If p=1 Then
{l5[1],k}»l5
Else
{l5[1],l}»l5
EndIf
listÐmat(l3)»m3
listÐmat(l4)»m4
listÐmat(l5)»m5
m3*m4»m6
{l6^(ª1)*l5}»l1
l1[1]»m
l1[2]»n
(l1[3]-m)^2+(l2[3]-n)^2»o
ClrIO
Disp "H=",m
Disp "K=",n
Disp "R®=",o
Pause
Goto end
the error comes up here when i hit goto:
Code:
1»p
Else
ªi^(ª1)»i
EndIf
(l2[3]+l2[1])/2»j
(l1[3]+l1[1])/2»k
j-i*k»l
If p=1 Then
{l4[1],0}»l4
that is the display on the screen
this is so far the only bug in my whole program

First of all:
Code:
If i=0 Then
{0}»l4:2»p
Else
0»p
ªi^(ª1)»i
EndIf
In one of these alternatives, you don't define what l4 should be. This will cause an error.
Second error that I notice is in
Code:
listÐmat(l3)»m3
listÐmat(l4)»m4
listÐmat(l5)»m5
m3*m4»m6
. This stores a 1x3 matrix to m3, a 1x3 matrix to m4, then tries to multiply them. I don't foresee that working.
You could optimize lots of that, in particular with the when() command (look it up if you don't know it). |
