I don't know where you're getting your information from. According to the Word VBA help file:

Split Function

Description
Returns a zero-based, one-dimensional array containing a specified number of substrings.

Syntax Split(expression[, delimiter[, limit[, compare]]])

The Split function syntax has these named arguments:
Part Description
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 character 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.
limit Optional. Number of substrings to be returned; –1 indicates that all substrings are returned.

compare Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings section for values.

Settings
The compare argument can have the following values:
Constant Value Description
vbUseCompareOption –1 Performs a comparison using the setting of the Option Compare statement.
vbBinaryCompare 0 Performs a binary comparison.
vbTextCompare 1 Performs a textual comparison.
vbDatabaseCompare 2 Microsoft Access only. Performs a comparison based on information in your database.

If you care to look at some of the numerous VBA posts I've made here, you'll see plenty of implementations.
