Arrays on batch script - arrays

Question

Everyone,
I'm trying to do a differential backup with svnadmin dump --incremental commmand. My idea is so basic, to read the multiple svn repositories using the command dir and to put into a text file called "input", to read it line by line and put into variables.
Get the last revision of the repositories with full backup script and write in a text file called "output" and put into a variables.
Everything is done, but I can't use the svnadmin dump because I need the variables (arrays) inside the loops. How can I do it? Please, help me, I tried so many times and doesn't work still ):

Answer 1

Without having seen fully through your code IMO lines 47..50 have an improper setting of the parentheses, try changing to:
(for /F "delims=" %%g in ('svnlook youngest E:\svn\repositorios\!Line[%%i]!') do echo %%~g
) > E:\Backup\SVN\New\last_rev_!Line[%%i]!_new.data
An editor like Notepad++ helps to find/visualize corresponding pairs of parentheses.
