in reply to Memory reusability

Perl does support reuse of memory, but:

The perl binary aquires memory for the perl program but this memory is never released to the operating system as long as the perl program runs.

So inside a running program the memory is reused but never freed.

    Dear busunl ,
    Do you meant to say that each perl program will consume their required memory when it starts ?
    One more question is whether it acquires more memory during run time

      It does not acquire all memory when it starts.

      It will get more memory during runtime when needed.

      There are two major points in perl memory management:

      1. You don't have to bother, perl will do that for you
      2. Memory will not be freed during runtime

      That's all.
