Mid Reverse Function
String Manipulations Class

Public Function MidReverse( _
      ByVal vString As Variant _
    , ByVal vPos As Variant _
    , Optional ByVal vLength As Variant _
    ) As Variant

"Middle String Reverse"
Similar to the Visual Basic Mid function, except that the returned string is constructed by moving backwards through vString instead of forwards.

Examples:

       MidReverse("123456789", 4) = MidReverse("123456789", 4, 4) = "4321" ' #1
       MidReverse("123456789", 6, 4) = "6543"
    whereas
       Mid$("123456789", 6, 4) = "6789"

vString: The string from which a portion is to be extracted. Function returns Null if vString is Null or cannot be fixed up to a String.

vPos: The starting character position within vString. vPos defaults to the last position within vString if it is Null or cannot be fixed up to a number.

Function returns an empty string if vPos is <= 0 (less than or equal to zero).

Function returns an empty string if vPos is beyond the end of vString.

vLength: The number of characters which are to be extracted from vString. vLength defaults to the starting position (vPos) if it is missing or Null or cannot be fixed up to a number, as in example #1.

Function returns an empty string if vLength is <= 0 (less than or equal to zero).

vLength defaults to the starting position (vPos) if it is greater than vPos.
