Your regex will also match filenames with more than one digit different.

Also it will match filenames which will begin with anything else and which have different extensions. To avoid that you will need to anchor the regex:

/^M8BBABONP\wM10\d\.dat$/

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
