Convert code from unstructured to structured

Can someone rewrite this code such that there are no line numbers.

If Abs(xi - x1) < Abs(0.00001 * xi) And Abs(yi - y1) < Abs(0.00001 * yi) Then GoTo 10
If Abs(xi - x2) < Abs(0.00001 * xi) And Abs(yi - y2) < Abs(0.00001 * yi) Then GoTo 10
If Abs(x1 - x2) < (0.0000001 * x1) Then If (yi - y1) * (yi - y2) < 0 Then GoTo 10 Else GoTo 20
If (xi - x1) * (xi - x2) < 0 Then GoTo 10
GoTo 20
10
If Abs(xi - x3) < Abs(0.00001 * xi) And Abs(yi - y3) < Abs(0.00001 * yi) Then GoTo 30
If Abs(xi - x4) < Abs(0.00001 * xi) And Abs(yi - y4) < Abs(0.00001 * yi) Then GoTo 30
If Abs(x3 - x4) < Abs(0.000001 * yi) Then If (yi - y3) * (yi - y4) < 0 Then GoTo 30 Else GoTo 20
If (xi - x3) * (xi - x4) < 0 Then GoTo 30
GoTo 20

Looks like homework ;-)

Saqib Husain, SyedEngineerAuthor Commented:
This is not homework. This is code that I had written years ago when I was not used to structured programming. I was going to do this myself but thought someone could get points and I may do something else.

Are you competent to do this or are you just trying to enjoy?

Hi,

Maybe this

If Abs(xi - x1) < Abs(0.00001 * xi) And Abs(yi - y1) < Abs(0.00001 * yi) Or _
    Abs(xi - x2) < Abs(0.00001 * xi) And Abs(yi - y2) < Abs(0.00001 * yi) Or _
    (xi - x1) * (xi - x2) < 0 Or _
    Abs(x1 - x2) < (0.0000001 * x1) And ((yi - y1) * (yi - y2) < 0) Then 
    If Abs(xi - x3) < Abs(0.00001 * xi) And Abs(yi - y3) < Abs(0.00001 * yi) Or _
        Abs(xi - x4) < Abs(0.00001 * xi) And Abs(yi - y4) < Abs(0.00001 * yi) Or _
        (xi - x3) * (xi - x4) < 0 Or _
        Abs(x3 - x4) < Abs(0.000001 * yi) And ((yi - y3) * (yi - y4) < 0) Then
            F = 1
    End If
End If

Don't be so rude! I didn't want to bother you, I was just asking ;-)

Putting a comment on a question sends it into low priority and attracts less experts. So unless you are contributing positively to the question or have a good point to make you should not start responding. That was why I was a bit matter-of-factly.

Alex, if you had looked to the right of the screen you would notice the Hall of Fame.

ssaqibh is regularly in the top 10 so I don't think he would be posting a question on here for homework; overloaded with work so making the most of other's expertise, maybe!

Thanks

Wow you really spent a lot of time on this.

I was thinking on a followup question and it appears that your code would be more adaptable to that question compared to the code accepted. Just standby while I prepare the question.
