expression

Required. String expression containing substrings and delimiters. If expression is a zero-length string, Split returns an empty array, that is, an array with no elements and no data.

delimiter

Optional. String used to identify substring limits. If omitted, the space character (" ") is assumed to be the delimiter. If delimiter is a zero-length string, a single-element array containing the entire expression string is returned.

count

Optional. Number of substrings to be returned; -1 indicates that all substrings are returned. If omitted, all substrings are returned.

compare

Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values. If omitted, a binary comparison is performed.

The compare argument can have the following values:

The following example uses the Split function to fill an array from a string that uses "|" as a delimiter.

Dim MyString, MyArray, i
MyString = "VBScript|is|fun!"
MyArray = Split(MyString, "|", -1, 1)
' MyArray(0) contains "VBScript".
' MyArray(1) contains "is".
' MyArray(2) contains "fun!".

For i = 0 to UBound(MyArray)
   MsgBox (MyArray(i))
