winfinit User Jun 2, 2008, 3:33 PM Post #2 of 3 (189 views) Re: [jigneshjsoni] address of a array variable [In reply to] Can't Post hello, i think you are talking about a reference (it is not a data address of your memory, so it is not similar to & in C) if you need to find/create a reference in perl you can do that with a "\" below example will print a reference number and a content of an array. winfinit:~ winfinit$ cat 4 #!/usr/bin/perl @array = qw/1 2 3 4 5 6/; $var = \@array; print "Reference: $var\n"; for ($i=0;$i<=$#array;$i++) { print $var->[$i] . "\n"; } winfinit:~ winfinit$ perl 4 Reference: ARRAY(0x801740) 1 2 3 4 5 6 read up on that article that i attached above it also talkes about how to get a typeglobs from a symbol table.

The "address" of an array variable is not something I have ever heard of. There is the index of an array variable 0, 1, 2 etc. Which is just its place in order in the list, 0 being the first position. -------------------------------------------------
