First :
Your assigning a newline to the "$/" scalar: $/ = "\n";
Why? Get rid of it.

Second:
The split: split (/|/, $/);
Should be : split (/\|/, $_);

Third:
You should escape the pipes in the print statement:
"$date|$time|$name|$street|....etc";
Should be: |$date\|$time\|$name\|$street\|....etc";

Hope it helps along with my previous response.

Greg
