Ok, so after that I am going to have three different possible $file variables and depending on certain conditions i want to return one of the three to be passed into another sub rountine, how can I set it up so that I can pass in the return value from my file sub whatever it is, to another sub and do it all in the main program, Something along these lines:

#Run File sub routine that returns either file1, file2 or file3

#call next routine and pass in that returned value

Next_sub(Whatever the returned value is..);

I am just looking for a way to do this without calling the next sub routine from the file sub conditional statements, because both the routines need to be as general and reuseable as possible. Thanks
