Solved Searching variables in a batch file

What I basically want to do is to search all the variables, or specified variables, for a cirtant word, letter or number. I know this can be easily done with an SQL database file but I'm trying to keep everything in one file. So again, just like searching for information in a database I want to search variables for a word, and if they contain that word, I want the file to display the variable(s) that match the search parameters. I know it can be done but I can't find how to do it.
