A termination analyzer correctly determines the halt
status of an input program specification for every
input that this program can take. A program specification
taking  zero inputs is merely the simpler case of this
same algorithm.

So you do. Perhapts it is a matter of taste but honest people

Yes. But the meaning of "termination analyzer" excludes analyzers
that don't analyze programs that do take inputs.

 Call a spade a spade if you want to be understood. If you constantly
changing words to other words that are no better you have no reason
to expect any understanding. You can expect people to understand
Common Language and terms defined in the same message or in the
message you are replying to but not ordinary words with unusual
random meanings.

On page three a code snippet is analyzed that takes
no input and its not even a function.

 That does not contradict what I said. But the algorithm on the sixth
page (1301) illustrates my point that ability to hadle programs with
input is essential (though the purpose of the algorighm is to
illustrate someting else).
 

A termination analyzer is required to determine the
halt status of at least one program/C function for
all the inputs/arguments that this program/function
takes, including zero inputs/arguments.
