You can use the match pattern function under the string palette. This will allow you to specify ascii characters and then you can search through the 2d array by splitting it up by rows or columns. You will have to make your own recipe to solve this one, but it will be a combination of these elements and maybe a for loop to index through the arrays. Hope this helps.
