Cat Line Sub
String Manipulations Class

Public Sub CatLine( _
      ByRef rTo As Variant _
    , ByVal vFrom As Variant _
    )

"Concatenate Line"
Add a line of text onto the end of a string representing a paragraph.
Concatenate the string representation of a value onto the end of a string, preceded by carriage return and new line characters unless the target string rTo is empty.

Example: 
       CatLine S, "New"
    is the same as
       S = S & Chr$(13) & Chr$(10) & "New"
    or
       S = S & vbCrLf & "New"
except that no carriage return and line feed characters are added when the target string (rTo) is empty.

    Cat Subroutine
Subroutine silently does nothing if both arguments (rTo and vFrom) are Null.
