For people who handle CMD scirpting, I think should be a piece of cake. I need to set a variable in my script equal to an extern file. I have control over the file so I can either make the file named something specific or I can create an empty file and set the first line equal to the value. So, how do I read a filename into a variable or a read a line from a file into a variable. Thanks!

More details... Use the "for" command to read from a text file and process info in it. The line
for /F %%i in (master.csv) do set MyFile=%%i
will read each line in the file master.csv, set %%i to the line, and run "set MyFile=%%i" for each line. At the end of this, MyFile will be equal to the last line.
What you need, my friend, is Clay's Utilities for DOS Batch Processes. We use them to automate Ghostwalker after imaging by reading the system Id from bios on Dell machines, but they work for just about anything. They add true power to batch and cmd scripts.

Also, Dirk Loss' Windows-Tools on CD-ROM site has a great section of command-line tools. Browse down the page.

Take the time to get the hang of these, they're great.
Good Luck,

To set a variable in a script, use the set command. Here are some examples:
::Set MyFile to a constant filename
set MyFile=filename.txt
::set MyFile to the first parameter (eg: if your script was called test1.bat, and you typed "test1.bat filename.txt" on the command line)
set MyFile=%1
::set MyFile to the last line of filelist.txt
for /F %%i in (master.csv) do set MyFile=%%i
::Using any of the above statements will set MyFile. To "use" MyFile, surround it in percent signs %.
echo MyFile is now %MyFile%
