Unit 4 Programming The Basic Computer Pdf Pdf Assembly Language We use a short main, and other functions instead of using one long main function. • separating a solution into a group of modules, each module is easier to understand, thus adhering to the basic guidelines of structured programming 4. use of modules (modularity) usually reduces the overall length of programs 5. Visual basic allows you to declare a function or subroutine with parameters that are either a copy (pass by value) or a reference (pass by reference) to the original value.
Chapter 4 Pdf Control Flow Computer Programming The corresponding formal parameter acts as a local variable, whose value is transmitted back to the caller’s actual parameter e.g., void fixer(out int x, out int y) { x = 17; y = 35; }. The procedure for branching to a subroutine and returning to the main program is referred to as a subroutine linkage. the bsa instruction performs an operation commonly called subroutine call. Objectives: introduce subroutines, subroutine nesting, processor stack, and passing the parameters to subroutines. 1. subroutines. in a given program, it is often needed to perform a particular sub task many times on different data values. such a subtask is usually called a subroutine. A parameter is a piece of data that we can ‘pass into’ a subroutine when it is called. this allows us to give the subroutine specific data which can then be used within the subroutine. the example below starts to explain how parameters work with subroutines.

One way to break up a complex program into manageable pieces is to use subroutines. a subroutine consists of the instructions for carrying out a certain task, grouped together and given a name. elsewhere in the program, that name can be used as a stand in for the whole set of instructions. Understanding how to use parameters within subroutines is key to creating effective and reusable code. it forms a significant part of procedural programming, leveraging the strength of subroutines to prevent repetition and improve the structure of a program.
