open a file generated dynamically

a file named "summary.####" is generated dynamically where #### is a number
with unknown digits (i.e. maybe 1 to 9), how can I ask perl to open this
file for further processing?

You will have to determine the actual file name first, e.g. by using glob()
or opendir() and readdir() and then isolating the desired name from the
list.
