Determining the Length of a String

This tip applies to Word 2007, 2010, 2013, 2016, 2019, and 2021

It is hard to imagine a function used more often with strings than the Len() function. This simple little function returns the length of any string. The following are a few examples that can work in your macros:

A = Len(MyString)
B = Len("This is a test")

The first line returns the length of the characters in the variable MyString. The second returns the number of characters between the quote marks (in this case, 14—remember that spaces count as characters).

If you want to determine the length of a selection, you follow a bit different approach:

C = Len(Selection)

This line returns the length of the current text selection in the document. Remember when calculating the length of a selection that paragraph marks (hard returns) count as two characters. That is because they are each really a carriage return followed by a line feed, even though all other macro commands treat them as a single character.
