I am using the following piece of code to pull out all of the strings that end in xls. The problem I have is that I need to define my own scalar (instead of $_) for looking through each line of the array created with readdir(DIR) 
@sheets = grep{substr($_,-3) eq 'xls'}readdir(DIR);

Any ideas, my friends?
I know that I could assign readdir(DIR) to an array, and using a foreach command, but I'd prefer it all on one line.......
