This example uses the Mid statement to replace a specified number of characters in a string variable with characters from another string.
Dim MyString
MyString = "The dog jumps" ' Initialize string.
Mid(MyString, 5, 3) = "fox" ' MyString = "The fox jumps".
Mid(MyString, 5) = "cow" ' MyString = "The cow jumps".
Mid(MyString, 5) = "cow jumped over" ' MyString = "The cow jumpe".
Mid(MyString, 5, 3) = "duck" ' MyString = "The duc jumpe".
