LLE

 LLE (string-a, string-b)

 Class:  Elemental function - Generic

 Returns a value of true if the first character string is less than
 or equal to the second character string, based on the ASCII
 collating sequence - even if the processor's default collating
 sequence is different.  In VSI Fortran, LLE is equivalent to the
 <= operator.

 The ASCII collating sequence determines the relationship between
 the arguments.

 The arguments must be character expressions.  The result is a
 LOGICAL*4 value.

 This function cannot be passed as an actual argument.
