The comment lines that come right after the function statement provide the help t… When writing the sub, we use the “Sub” keyword and a name as the procedure name to declare the sub. In the example, we created the ExitFunc which returns an integer The first Sub is built-in, the second would be a custom Sub you wrote. Let's say you want to add two numbers. Once we click on the module, a new module will be added in the worksheet and on the right-hand side of General page, where we will write the VBA function coding. We often use Subs and Functions often not thinking about their true potential and how much we can squeeze out of a regular VBA Function. The sub procedure should be followed by the task to be performed, written in VBA language. Thus, for example, length() returns the number of characters in a string, and not the number of bytes used to represent those characters.

Subfunctions cannot access variables used by other subfunctions, even within the same M-file, or variables used by the primary function of that M-file, unless you declare them as global within the pertinent functions, or pass them as arguments. Exit a Function in VBA. You can also write programmer-defined procedures (Subs and Functions), which you would use not to respond to an event, but to modularize your code.
