When we talk about VB commands, such as "Print", or "Open", we are talking about a command which tells VB to run a section of code which performs the Print or Open function.

You can create your own "commands" but we call them procedures instead. The two types of procedures VB supports are called Subroutines and Functions.

For example, when you use the square root function in VB:

x = SQR(25)

This is a VB function called SQR. It passes the value 25 to the function and the function returns the square root and places it into x.

It's important to note that procedure calls include a list of values (or variables) which are passed to the procedure. The procedure is allowed to change those variables when it is executed - but you make the decision by the choice of your code within the procedure.
