With a regular expression you can use the $ to signify the end of the string so a regulat expression catching the following: $your_long_number =~ /.*(\d{3})$/; print "My 3 digits are: $1\n"; Just saw Shawn's solution which I assume will work as well though I am not sure what the \z is for looking that up :-) Regards, Rob
