## Getting Dynamic Text Captions with Macros

The first time I’ve heard of macros was when I first used Microsoft Excel. Macros are defined as tiny snippets of programming codes to customize and enhanced the results on a spreadsheet or to perform repetitive tasks. In our applications, even though they do a lot of complicating codes at the background to get the result, it does work in a different manner. Here we used them much as a preset programming function calls. If you are familiar with programming, a function is a set of procedures to get a result. In the context of Text Captions, macros plays in an important role in making your text captions dynamic in a way.
