How to use Excel VBA to send output data table to created .csv file with options?

Hi everyone, Say I have already XVar.csv file and using MS VBA I want to automate writing a data vector X[a,b,c] to XVar.csv or appending it to already existing table in XVar.csv.How this could be written in a simple vba code? Thanks a lot in advance.

Well you can use the below mentioned command and let me know whether it is working or not.

Code:

---

Sub UpdateCSV()
Open "C:\TestFolder\junk\AA.csv" For Append As #1
Print #1, "Hello World"
Close #1
End Sub
