 Class:  Inquiry function - Generic

 Returns the number of characters in the argument.  The argument
 must be a character expression.

 The "kind" must be a scalar integer initialization expression.

 The result is an INTEGER*4 or INTEGER*8 value.  If "kind" is
 present, the kind parameter of the result is that specified by
 "kind"; otherwise, the kind parameter of the result is that of
 default integer.  If the processor cannot represent the result
 value in the kind of the result, the result is undefined.

 The setting of compiler options that specify integer size can
 affect the result of this function.
