set variables in batch to text file values

I have a text file which is made up of a new value on each line. The amount of lines will vary (expand over time).

I would like to set a variable in a batch file for each of those values. Does anybody know how to do that?

If you just want to read from each line of the file into separate variable then use this. It can also be configured into a loop if you want it to get all the lines instead of just specific lines that way you wouldn't have to put 100 commands for 100 lines.

setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in (TEXTFILEPATH.txt) do (
set /a N+=1
set v[!N!]=%%a
)
set line1=%v[1]%
set line2=%v[2]%
set line3=%v[3]%
set line4=%v[4]%

echo %line1%
echo %line2%
echo %line3%
echo %line4%

endlocal

Make sure the endlocal is after the use of the variables.

If you want to write to specific lines in the text file, here is a post for that.
