What is gastroparesis? Gastroparesis, also called delayed gastric emptying, is a disorder that slows or stops the movement of food from the stomach to the small intestine. Normally, the muscles of the stomach, which are controlled by the vagus nerve, contract to break up food and move it through the gastrointestinal (GI) tract.
A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. To ensure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. The scientist focuses his or her observations on the dependent variable to see how it responds to the change made to the independent variable.
, and so on. However, it's much more efficient to create a single. array variable that can hold up to 20 names. VBA creates a single variable with 20 different slots into which you can add data (such as employee names). Such an array variable is akin to an Excel range that consists of 20 cells in a row or column: the range is a single entity, but it contains 20 slots (cells) into which you can insert data. The major difference is that you almost always use an array variable to hold data of a single type, such as. . When you declare an array variable you specify the data type, as shown here: As you can see, this declaration is very similar to one you would use for a regular variable. The difference is the 19 enclosed in parentheses.
