The following example reads the text file “file1.txt” line by line into the variable ‘var’:

@echo off
setlocal enabledelayedexpansion

set count=0

for /f "tokens=*" %%x in (file1.txt) do (
    set /a count+=1
    set var[!count!]=%%x
)

echo %var[3]%

Output:

This is the third line

echo %var[3]% will display the 3th line in file1.txt.

I need to write a small program (8-10 lines long) but I have forgotten how. Anyone willing to help?

  I have a file (List.txt) that contains two fields. Field#1 is an URL. Field#2 is a file name.
  
  I want to check for the existence of Field#2. If it does NOT exist I want to run a PS command using Field#1
  
  Basically:
```
(For loop to end of file.)
read Field#1, Field#2
If NOT exits Field#2 do
  call powershell -Command "invoke-WebRequest https://WvvwCUcr-OXe6ClIw.mp4 -Outfile C:/archives/You_CAN_Make_Time_for_Bible_Study.mp4"
```
  I used to write programs but 2 years ago I was “sick unto death.” Now it’s all gone. I don’t know where to start.
