Languages Focus A data structure in which individual values (called elements or items) may be located by reference to one or more integer index variables, the number of such indices being the number of dimensions in the array.
Arrays can start with an index value of 0 or 1, sometimes referred to as 0 based or 1 based.
ASP Classic:
x = Array()
Arrays in ASP Classic use a 0-based indice.
Use UBound to get the number of elements. UBound returns -1 if the array has no elements, 0 if it has 1, 1 if it has 2, etc.
Syntax Example:
Dim MyArray, i MyArray = Array("Mike", "Lisa", "Felicia", "Nathan") If UBound(MyArray) > -1 Then For i = 0 to UBound(MyArray) Response.Write MyArray(i) Next End If
Cross Reference Examples:
Access VBA:
x = Array()
Arrays in Access VBA use a 0-based indice. Use UBound to get the number of elements. UBound returns -1 if the array has no elements, 0 if it has 1, 1 if it has 2, etc.
Syntax Example:
Dim MyArray As Variant Dim i As Integer MyArray = Array("Mike", "Lisa", "Felicia", "Nathan") If UBound(MyArray) > -1 Then For i = 0 To UBound(MyArray) MsgBox (MyArray(i)) Next End If

Array[] type
Arrays in ObjectPAL use a 1-based subscript (also known as an index). Use [] with a subscript to refer to an element (i.e. MyArray[1] , MyArray[2] ).
The number of elements for a given array in ObjectPAL are either fixed or resizeable. Specify the size when you declare it for fixed. Use size() to get the number of elements, size() returns 0 if the array has no elements. Use setSize() , grow() , addLast() , etc. to add elements to an array.
Syntax Example: var MyArray Array[4] String ;Fixed size array. i LongInt endVar
MyArray[1] = "Mike" MyArray[2] = "Lisa" MyArray[3] = "Felicia" MyArray[4] = "Nathan"
if MyArray.size() > 0 then for i from 1 to MyArray.size() msgInfo("", MyArray[i]) endFor endIf
Delphi:
x=Array[0..3] of string;
Delphi supports both static and dynamic arrays as well as single and multi dimensional arrays.
Syntax Example: var MyArray: array[0..3] of string; i: Integer; begin MyArray[0] := 'Mike'; MyArray[1] := 'Lisa'; MyArray[2] := 'Felicia'; MyArray[3] := 'Nathan'; for i := 0 to High(MyArray) do ShowMessage(MyArray[i]); end;
VB Classic:
x = Array()
Arrays in VB Classic use a 0-based indice. Use UBound to get the number of elements. UBound returns -1 if the array has no elements, 0 if it has 1, 1 if it has 2, etc.
Syntax Example:
Dim MyArray As Variant Dim i As Integer MyArray = Array("Mike", "Lisa", "Felicia", "Nathan") If UBound(MyArray) > -1 Then For i = 0 To UBound(MyArray) MsgBox (MyArray(i)) Next End If
