Save lines of text in variable

Hey guys,

I am trying to pull values from a text file and save them to variables in a batch script. Also, I want the script to print out all of the variables when I call them. The amount of lines in the text file will vary based on the user, so that will have to be taken into account when echoing them, right?

Here is an example text file that I would like to read the values from

(-----start of test.txt---------)





(and so on, depending on the user)
(-----end of test.txt---------)

I would like it to save all of those in variables, and then echo them to the console as

1. BDS-20100516-1646

2. Fresh1.1

(and so on, depending on how many there are)


I need the values stored in variables because I want to call those values later after a:

set /p restore=(one of the options)

then do something with which ever one they choose with an

if %restore% == 1 (do something with the variable)

can you guys help me out? I hope I made this clear.. . I know it probably looks confusing.

I'll try to clean it up if I think of a way :P

here's a simple menu system using "find" instead of storing all values into array (which is also reasonable approach, but,
for me, boring). I think you;ll get the idea how to elaborate further from this sample:
@echo off & setlocal
:: display menu
for /f "tokens=1* delims=[]" %%a in ('find /v /n "" %user%') do (
echo %%a. %%b
set /p sel=select from list:
set /a sel-=1
if %sel% equ 0 (set skip="tokens=*") else (set skip="skip=%sel% tokens=*")
:: if you want your index to line up, add here: set /a sel+=1
call :xx %skip% %sel%
goto :eof
:: now extract index and string-value from the file (alternative to
:: storing variables into array)
:: no "IF" construct required, since index goes to appropriate label.
for /f %1 %%z in (%user%) do echo %2 %%z & call :%2 %%z & goto :eof
echo ZERO: menu item %1 process
goto :eof
echo ONE: menu item %1 processed
goto :eof
echo TWO: menu item %1 being processed
goto :eof

@echo off & setLocal EnableDELAYedeXpansion

set N=
for /f "tokens=* delims= " %%a in (BDSfile) do (
set /a N+=1 & set V!N!=%%a

for /L %%i in (1 1 !N!) do echo %%i. !V%%i!

Wow, Mechanix2Go, That worked great

Exactly what I was looking for :)

Now, I wanted them to be able to choose one of them with a set /p like,

Which one?

then they enter a #.

And then it uses that value from the text file to do what I want.

(I'm using it to restore a Nandroid image backup to an Android phone via command line)

how would I go about grabbing one of those saved variables?

say, they choose #4,

how would I call the variable of the 4th item in the list?

set /p c=pick one

I really mean it, showing me that opened up a whole new way to code for me, w/ setLocal EnableDELAYedeXpansion, never had used it before, but the possibilities are endless now! (well, almost haha)
