Procedures and functions provides a means of producing structured programs. Rather than repeating the same operations at several different places in the program, they can be placed in a procedure or function. This not only makes the program easier to read, but saves a lot of time and effort in maintaining the program.

Visual Basic offers different types of procedures to execute small sections of coding in applications. The various procedures are elucidated in details in this section. Visual Basic programs can be broken into smaller logical components called Procedures.

Procedures And Functions

In computer programming , a subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed. Subroutines may be defined within programs, or separately in libraries that can be used by many programs. In different programming languages, a subroutine may be called a routine , subprogram , function , method , or procedure. Technically, these terms all have different definitions. The generic, umbrella term callable unit is sometimes used.

We have been using simple examples till now as here the purpose is learning VBScript. But in real-world scenario, the code is not as simple as that. When you try to implement something that is useful, the code might get more complex. There could be hundreds of lines stretching across many pages. If you do not organize the code properly, the whole process of coding, debugging and managing the code will become really complex.

We have been using simple examples till now as here the purpose is learning VBScript. But in real-world scenario, the code is not as simple as that. When you try to implement something that is useful, the code might get more complex. There could be hundreds of lines stretching across many pages. If you do not organize the code properly, the whole process of coding, debugging and managing the code will become really complex. So, you should organize or modularize the code carefully so that your code becomes easily manageable.

We use procedures and functions to create modular programs. Visual Basic statements are grouped in a block enclosed by Sub , Function and matching End statements. The difference between the two is that functions return values, procedures do not. A procedure and function is a piece of code in a larger program. They perform a specific task. The advantages of using procedures and functions are:.

VBScript Functions & Procedures with Example

Вздох облегчения вырвался из груди Беккера. Он сразу же перешел к делу: - Я могу заплатить вам семьсот пятьдесят тысяч песет. Пять тысяч американских долларов.  - Это составляло половину того, что у него было, и раз в десять больше настоящей стоимости кольца. Росио подняла брови.

Мою колонку перепечатывают издания по всему миру. - Сэр! - Беккер поднял обе руки, точно признавая свое поражение.  - Меня не интересует ваша колонка.

Должно быть, это какая-то ошибка. Следопыт показывал адрес, не имеющий никакого смысла. Взяв себя в руки, она перечитала сообщение.

Выглянув в пустую шифровалку, он принял решение. На загрузку программы и поиск вируса уйдет минут пятнадцать. Скажи, что ничего нет, - прошептал .

Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения. Генераторы внизу производили постоянный низкочастотный гул, что делало акустику в шифровалке какой-то загробной, присущей миру призраков.

For example, while we were using forms so far, we couldn't write code on a form.

network department. Programming with Visual Basic II one important difference- function procedures return a value (e.g., give a value back) to the caller.

A function is similar to a procedure but the main purpose of the function is to accept a certain input from the user and return a value which is passed on to the main program to finish the execution.
