[Jax.PM] references

[Jon Day - DaySite]

After my last 'whore' posting, here is something more in-line with the
purpose of this list.

Does a reference go away after the program that wrote it finishes
running?  Or can it be reused from another instance of the same or other
scripts called within a short period of time?

>perl -de test.pl

main::(-e:1):   test.pl
  DB<1> $n = 'abc';
 
  DB<2> $ref = \$n;
 
  DB<3> print "$ref\n";
SCALAR(0x83a2c7c)
 
  DB<4>q

---

>perl -de test.pl

main::(-e:1):   test.pl
  DB<1> print "REF: $ref\n";
REF:

  DB<2>q
