LGT

 LGT (string-a, string-b)

 Class:  Elemental function - Generic

 Returns a value of true if the first character string is greater
 than the second character string, based on the ASCII collating
 sequence - even if the processor's default collating sequence is
 different.  In VSI Fortran, LGT 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.
