Procedure calls are an important concept in Visual Basic for Applications (VBA) and allow you to reuse code and make your code more modular and organized. A procedure call is when you execute a procedure, also known as a Sub or Function procedure, by calling its name. When you call a procedure, the code within the procedure is executed and the procedure can also take parameters, which are values that are passed to the procedure when it is called.
To call a procedure in VBA, you simply use its name, followed by any required parameters, in a line of code. For example, if you have a Sub procedure named “DisplayMessage” that displays a message on the screen, you could call it using the following line of code:
Call DisplayMessage(“Hello, World!”)
When the above line of code is executed, the “DisplayMessage” procedure will be called and the message “Hello, World!” will be displayed on the screen.
It is also possible to nest procedure calls, which means that one procedure can call another procedure. Nesting procedure calls can be useful when you want to reuse code within a procedure or break down a complex task into smaller, more manageable pieces.
In conclusion, procedure calls are an important part of working with procedures in VBA and allow you to reuse code and make your code more modular and organized. By calling procedures and passing parameters when necessary, you can easily automate repetitive tasks and make your VBA code more efficient. Whether you are a beginner or an experienced VBA user, understanding how to call procedures will be a valuable addition to your VBA toolkit.
