A '''calling section''' is a section or [[block?]] of code that makes a call to a subroutine or [[function?]].
A '''calling point''' is the instruction within a section or block of code that makes the call to the [[subroutine?]] or [[function?]]. This will usually be a call instruction or function name.
The return point is the instruction that immediately follows the calling instruction. This will be the next instruction to be executed after the [[subroutine?]] or [[function?]] has returned.
Evaluation of return values
The code at the return point within a program may evaluate the [[return_code?]] given by the [[subroutine?]] or [[function?]] that was called.
