Role of stack frames in subroutine calls: Be able to explain how a stack frame is used with subroutine calls to store: • return addresses • parameters • local variables
- This point belongs to Programming, especially Role of stack frames in subroutine calls.
- You need to be able to role of stack frames in subroutine calls: Be able to explain how a stack frame is used with subroutine calls to store: • return addresses • parameters • local variables.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect Role of stack frames in subroutine calls to exam-style questions, flashcards, and revision notes for Programming.
Quick student answer
What is the main purpose of a stack frame when a subroutine is called?
Direct answer
To store information needed to pause and later resume the calling subroutine
Key terms
- Stack frame: The section of the stack containing information for one active subroutine call, including its return address, parameters and local variables.
- Return address: The location of the instruction in the calling subroutine where execution resumes after the called subroutine finishes.
Common trap
Confusing a stack frame with the whole stack: A stack frame belongs to one particular active call. Several frames may exist on the stack at the same time, with each one storing its own return address, parameters and local variables.

- Data types: Understand the concept of a data type. Understand and use the following appropriately: • integer • real/float • Boolean • character • string • date/time • pointer/reference • records (or equivalent) • arrays (or equivalent). Variables declared as a pointer or reference data type are used as stores for memory addresses of objects created at runtime, ie dynamically. Not all languages support explicit pointer types, but students should have an opportunity to understand this data type. Define and use user-defined data types based on language-defined (built-in) data types.
Data types
- Programming concepts: Use, understand and know how the following statement types can be combined in programs: • variable declaration • constant declaration • assignment • iteration • selection • subroutine (procedure/function). The three combining principles (sequence, iteration/repetition and selection/choice) are basic to all imperative programming languages. Use definite and indefinite iteration, including indefinite iteration with the condition(s) at the start or the end of the iterative structure. A theoretical understanding of condition(s) at either end of an iterative structure is required, regardless of whether they are supported by the language being used. Use nested selection and nested iteration structures. Use meaningful identifier names and know why it is important to use them.
