Returns a string created by joining a number of substrings contained in an array.
The Join function syntax has these parts:
Required. One-dimensional array containing substrings to be joined.
Optional. String character used to separate the substrings in the returned string. If omitted, the space character (" ") is used. If delimiter is a zero-length string, all items in the list are concatenated with no delimiters.
The following example uses the Join function to join the substrings of MyArray:
MyArray(0) = "Mr."
MyArray(1) = "John "
MyArray(2) = "Doe "
MyArray(3) = "III"
MyString = Join(MyArray) ' MyString contains "Mr. John Doe III".
