If the limit is not specified, all substrings are returned


Syntax:
Split(string[, delimiter][, limit])

Parameters Description
string Required – string input that you want to parse into
a one-dimensional array using a delimiter and a limit
delimiter Optional – string delimiter that specifies
what separates the fields contained within the input string. If
no delimiter is given, space is used.
limit Optional – integer specifying maximum number of
fields to return to the one-dimensional array. If no limit is specified,
all substrings are returned.

Result Data Type Description
string() Returns a one-dimensional string array that contains all
of the substrings that were returned from the input string.


 *** 3. Split – Quick Example *** 
Dim strField As String = “This”
