H! How do I do this ?? a$(0) = "red" a$(1) = "blue" a$(2) = "red" a$(3) = "green" a$(4) = "purple" a$(5) = "purple" a$(6) = "purple" now I want to know that red is at place 0 and 2 and purple at place 4,5,6 I was testing things but that fails: aantal = 7 Dim a$(aantal) a$(0) = "red" a$(1) = "blue" a$(2) = "red" a$(3) = "green" a$(4) = "purple" a$(5) = "purple" a$(6) = "purple" For i1=0 To aantal For i2=0 To aantal If i1<>i2 Then ; If a$(i1)=a$(i2) Then ; ; Else ; EndIf EndIf Next Next Thanks, GC-Martijn |

aantal = 7 Dim a$(aantal) a$(0) = "red" a$(1) = "blue" a$(2) = "red" a$(3) = "green" a$(4) = "purple" a$(5) = "purple" a$(6) = "purple" For i1=0 To aantal For i2=0 To aantal If i1<>i2 Then ; If a$(i1)=a$(i2) Then ; ; Else ; EndIf EndIf Next Next When you dimension an array, you tell it the number of elements you want in it. In your case, aantal=7, which is for elements 0 to 6. When you do your For-Next loops, do them with a For i1=0 To aantal-1 For i2=0 To aantal-1 Otherwise, you really have 8 elemnts, 0 to 7. More than that, your code posted has semi-colons in front of various lines. The semi-colon is the way you tell Blitz to make that line a non-compiled comment, not code. Those lines wil not execute. |

THanks Sir Gak, It was the aantal-1 ;) How stupid... |
