The Split function separates a string into substrings and creates a one-dimensional array where each substring is an element.

There is one mandatory argument.

Expression

The Expression argument is a string expression.

Code:
<% mystring = "How now brown cow?" %>
<% myarray = Split(mystring) %>
<% =myarray(0) %>
<% =myarray(1) %>
<% =myarray(2) %>
<% =myarray(3) %>

Output:
How
now
brown
cow?

There are three optional arguments.

Delimiter)

The optional Delimiter argument specifies the characters (including blanks) you wish to use to separate the expression.

Code:
<% mystring = "How now brown cow?" %>
<% myarray = Split(mystring, "ow") %>
<% =myarray(0) %>
<% =myarray(1) %>
<% =myarray(2) %>
<% =myarray(3) %>
<% =myarray(4) %>

Output:
H
n
br
n c
?

Count)

The optional Count argument specifies the number of elements to return.

Code:
<% mystring = "How now brown cow?" %>
<% myarray = Split(mystring, " ", 2) %>
<% =myarray(0) %>
<% =myarray(1) %>

Output:
How
now brown cow?

Compare)

The optional Compare argument must only use the constant or value of the COMPARISON CONSTANTS.

In the example, by using VBTextCompare for the Compare argument, the split occurs at the b and ignores the upper case difference between the Delimiter argument "B".

Code:
<% mystring = "How now brown cow?" %>
<% myarray = Split(mystring, "B", 2, 1) %>
<% =myarray(0) %>
<% =myarray(1) %>

Output:
How now
rown cow?

Code:
<% mystring = "How now brown cow?" %>
<% myarray = Split(mystring, "B", 2, VBTextCompare) %>
<% =myarray(0) %>
<% =myarray(1) %>
