I don't think shift is bad. I find myself using it in a lot of code, especially modules that I write for office use. In some subroutines, I find myself using 3-5 shifts. In one of my modules (Student::Server), I've done this:
Most people would probably frown upon that usage, but I like it. If I only need one parameter (per variable), then it's much easier to avoid confusion about parameters. In the above sub, I expect an object, a filename, and an array ref (which contains the order of logging parameters). In other words, a call to usr_create would look like: $obj->usr_create('test.txt', [Last_Name, First_Name, State]); or even $obj->usr_create('test.txt', $aref); shift'ing out the necessary parameters avoids silly things like having a user pass too many arguments to the sub. In that case, anything not shift'ed out is discarded. Theodore Charles III Network Administrator Los Angeles Senior High 4650 W.
