The script is designed to show the variables and functions in the scripts, to avoid duplication, to be able to fearlessly copy of the code of one script to another. Allows you to keep track of variable names to avoid duplication when you want to rename a variable, eg $Path and $PathName. When replacing the $Path will damage $PathName, so you need to temporarily rename $PathName, then rename $Path, and then restore the $PathName. Variables and functions are displayed in one instance and sorted. T
