HI Eri,
The my is probably not doing what you think it is. Otherwise it would constitute a
redeclaration error. My guess

Assigning to a scalar variable puts the right-hand-side in scalar
context anyway.
my $total_elements = @in
Dear All,
I'm greatly overwhelmed by your quick help to my problem.
Here's the corrected code:
#!/usr/bin/perl -w

interpolated before the string is taken. So you could write the above as:
print "\t\[$_
