   Declare Operator <= ( ByRef lhs As WString, ByRef rhs As WString ) As 
   Integer

   Declare Operator <= ( ByRef lhs As T, ByRef rhs As T ) As Integer

Usage
   result = lhs <= rhs

Parameters
   lhs
      The left-hand side expression to compare to.
   rhs
      The right-hand side expression to compare to.
   T
      Any pointer type.

Return Value
   Returns negative one (-1) if the left-hand side expression is less than 
   or equal to the right-hand side expression, or zero (0) if greater than.

Description
   Operator <= (Less than or Equal) is a binary operator that compares an 
   expression less than or equal to another expression and returns the 
   result - a boolean value in the form of an Integer: negative one (-1) 
   for true and zero (0) for false. The arguments are not modified in any 
   way.

   When this operator is applied to string type data, then a 
   lexicographic/alphabetic order comparison is performed (ordered from the 
   numeric ASCII values of the characters of the two strings).

   This operator can be overloaded to accept user-defined types as well.

Example
   Operator > (Greater than) is complement to Operator <= (Less than or 
   Equal), and is functionally identical when combined with Operator Not 
   (Bit-wise Complement).

      If (69 <= 420) Then Print "(69 <= 420) is true."
      If Not (60 > 420) Then Print "not (420 > 69) is true."

Dialect Differences
   * In the -lang qb dialect, this operator cannot be overloaded.
