How to pass variable content from csv file to another file using batch file

Question

For example I have a .csv file name "sample.csv" that reads every row.Now I want to pass the contents of the sample.csv to another file "pass.txt"

(
FOR /F "tokens=1-18* delims=," %%A IN ('type C:\Users\sample.csv') DO (
  set A = %%A
  set B = %%B


  echo %%~A
  echo %%~B

 )
)>youroutputfilename
pause

I can generate another text file using the above code. However what if I want to pass the content of "A" and "B" to another file?

Sample content of pass.txt before script is run:

Put A content Here: 
Put B content Here:

How to do this using batch file?

Sample output after run should be:

Put A content Here: **Apple** 
Put B content Here: **Banana**

  echo Put A content Here: %%~A
  echo Put B content Here: %%~B
 )
)>pass.txt
