I need more information on macro

Hi Adebisi. A macro is a small computer program in itself, and behind the scenes are a whole series of other programs which turn the code you write in VBA into a series of electrical 1s and 0s. These are then translated by the processor of the computer and the corresponding software results produced - an Excel calculation, for example. If you become proficient in writing macros you will be well on your way to understanding how to program.

Hope this helps,

Anthony
