When coding a macro, use comment and tab.

Comment:

Texts after a semicolon(;) is recognized as a comment.
It is useful to use it as a short notes of the macro you created.

If you need to temporarily stop the macro coomands while debagging the marco commands, add semicolon to the head of the line so that such command becomes comment and will not be executed.

Tab:

You can indent a line using a tab key.
This helps to understand the structure of the macro commands.
