What do you mean by "common procedures?". Are you refering to procedures native to perl that are used regularly? Or procedures that YOU define that are common to programs that you are writing? (similar to C/C++ libraries)

If you want the latter (procedures that YOU define that are common to programs that you write), then the answer is yes. Create a module containing the procedures and use it in you program in the same way you would use any module.

Check Tutorials for some help on how to create them.

hope this helps,
