Sorry if this is a dumb question. In a batch file I want to read a sorted file, DIR.DAT, which has
lines like this:
B01001001.txt
B01001002.txt
B02001001.txt
etc. (data represents book#, chapter#, page#, and used in a book reading application all done in a batch file.)

The target I am looking for is the first 3 characters, for example B22
What I want to determine is which line has the last occurrence of the target.
If I were searching for B01, for the above example data, the answer would be 2 (line 2).

Is there a reverse-file-read method?
Thanks.

You could run it through a for loop and set a variable every time you locate the string you're looking for so that the variable gets overwritten every time and you eventually end up with the last instance.

This works here:

Thankyou both for your comments on a solution.
foxidrive, your solution works perfectly for what I need:
finding the last occurrence of a string in a file of file names
with no spaces, searching at the beginning of the line, and returning the line number.

I also want to know what the file name is. Here is that code:
