This section describes how to show the information on function call from the stack.

The CS+ compiler (CC-RL) pushes function-call information onto the stack, in accordance with the ANSI standard.

It is thus possible to learn the function call depth, the location of the caller, parameters, and other information by analyzing the function-call information.

This "function-call information" is called the call stack information; this term will be used in the rest of this document.
