That was a major argument for declaring variables: Undeclared variables are of type variant, with a minimum size of 16 bytes, whereas if you declare a variable as type integer, you use only 2 bytes.
The macro recorder is a good introduction into the world of VBA programming, but it's not meant to be your only teacher.
It provides a simplistic approach to coding with Excel’s object model, but is by far not a teacher of advanced or efficient programming methods.
Don’t rely solely on the macro recorder to teach you VBA programming; it’s meant only as an introduction, and you can’t rely on it for more advanced programming methods.
Tracy Syrstad, co-author of Excel 2016 VBA and Macros, provides 10 macro recorder tips that will take your VBA programming skills up a level or two.
