trouble with arrays again

[kor 5]

I have a tab deliminated file that I pull into an array. I then search to see if certain students are either enrolling, withdrawing, or moving. A move is a combination of a withdraw and an enroll.

Our system will not let you "enroll" a student unless they have already been withdrawn. As such, a withdraw will always proceed an enroll. The two might not always be one right after the other.. there might be other students enrolling/withdrawing in between that time. I have attached my sample data. The code below does everything I need it to do with the except of modifying the array to do the following.

If action = enroll then search the array (backwards) to see if there are any matching withdraws for this student (check is based on a duplicate ID number)

source row = withdraw row

destination row = enroll row

If there is a corresponding withdrawn action for user with ID number you are checking then change action to = "move" in the destination row, and delete the source row.

Loop, then spit out a new array.

Picture 1 would be the first (raw) array

Picture 2 SHOULD be what the fixed (clean) array looks like (but currently doesn't)

Here is the full code:

I've modified your function a little:

Func _SetAction(ByRef $aInput)
    For $i = UBound($aInput)-1 To $iRowStart Step -1 ; read array backwards
        Switch $aInput[$i][8] ; check action
            Case "Enroll"
                $iReturn = _ArraySearch($aInput, $aInput[$i][2]) ; search array for duplicate ID numbers
                If $iReturn >= 0 And $iReturn < $i Then ; if ID numbers found and row is less than current row
                    If $aInput[$iReturn][2] = $aInput[$i][2] Then ; compare source row ID number against destination row
                        $aInput[$i][8] = "move" ; modify action on destination row
                        _ArrayDelete($aInput, $iReturn) ; delete source row
                    EndIf
                EndIf
        EndSwitch
    Next
    Global $aClean = $aInput ; create new array and fill with clean data
    _ArrayDisplay($aInput, "ainput")
EndFunc   ;==>_SetAction

thank you. That was simple once I see what you changed.
