Actual - VBScript - Pass DOS-Like Arguments to Your Script for Flexibility and Control
Developers who have used DOS tools will be familiar with the "switches" used to supply Arguments or used as Arguments themselves. For example, listing the contents of a directory without any header information:
dir /ad /b
Or supplying data with "switches" like the drive letter:
doublespace /mount c:
Arguments are often passed to (VBSc

According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product
ript) scripts in a set order. The writer of the script perforce has to assume that the user of the script will supply ALL of the available Arguments in the correct order. We can improve upon the way Arguments are passed to scripts by using switches within our Argument line.
The benefits of passing switches are:

The absence of a switch for the filename will notify our script that the Argument is a filename.
Arguments passed to a script are held within the wscript.Arguments object. To access these Arguments we need to first instantiate an Arguments object:

We can now process the Arguments passed to our script. Let's call our script SearchLight.vbs and assume that the following Arguments are passed:
SearchLight.vbs /U /W boat,green,sailing BoatSales.csv
Our script's purpose is to return a unique list of green sailing boat names from BoatSales.csv.

We start by iterating through the Arguments passed and capturing the criteria. Though the Arguments object is an object with a Count method, we retrieve its Arguments starting at zero: Like an array. We'll make reading the code easier by adding a Constant called FIRST_ITEM, which is set to zero, and a Variable called LAST_ITEM which will
