You can replace the `command` syntax with the FOR syntax:
For example, to retrieve the author of a revision, you could use the
following syntax:
FOR /F "tokens=*" %%G IN ('%SVNLOOK% author -r %REV% %REPOS%') DO SET AUTHOR=%%G
Here is a working example:
@ECHO OFF
SET SVNLOOK=C:\PROGRA~1\Subversion\bin\svnlook
SET REV=122
SET REPOS="d:\project"
FOR /F "tokens=*" %%G IN ('%SVNLOOK% author -r %REV% %REPOS%') DO SET AUTHOR=%%G
ECHO "Author %AUTHOR%"
You can use the same syntax for other backquoted commands.
Important note: Thanks to the M$ shell script interpreter, this syntax
only works when executed from a .bat file. If you want to test it from
the command line, you need to replace the double %% with a single %
character.

Yes, that's the very issue: you should use the backquote feature.
If you don't, the script simply cannot work.
The trouble is that Windows shell interpreter do not understand
backquotes, so using them won't change anything. No using them will
not produce the expected results
You can see by yourself:
SET AUTHOR=C:\PROGRA~1\Subversion\bin\svnlook.exe author -r %REV%
%REPOS%, as per the original script, is supposed to place the author's
name of %REV% in the AUTHOR variable.
Run this command, and print out the AUTHOR value:
echo %AUTHOR%
I don't have a script that runs under Windows. I'm kinda allergic to
Windows-as-a-server ;-) I can give you some hints about how to adapt
the script.
