in reply to dup() in perl

There are a minimum of 3 steps involved in posting a SoPW node:
  1. Learn how to use the perl doc system
  2. (Assuming step 1 reveals nothing useful), perform super search/google site search on the Monastry
  3. Post a SoPW question

Of the 3 steps, it appears as tho' you've only considered the 3rd step since as others have posted elsewhere on this thread, the inormation is there to find.

A user level that continues to overstate my experience :-))
