In SATHER-K the simple values are integer and floating point numbers, characters, the Boolean values false and true which also serve as the simple values from which bit-sequences are built.
Additionally SATHER-K has reference values which refer to reference objects and stream objects.
Composite values, e.g., strings, are values composed from other values, especially from simple ones. The value of such an object consists of the values of its attributes. Arrays have an indexed set of unnamed attributes.
Bound methods are values 
method, bound
parameters 
which allow to determine the method to be called
at binding time rather than at calling time. At binding time
some or all of the arguments of the future calls may be specified as
bound arguments; the remaining parameters are called free
parameters (of the bound method).
