'=' is assignment, '==' is test for numerical equality. This loop will never
end, as $I gets assigned to the value 1 each time through the loop.

You probably don't want to change $i inside a 'for my $I ( 1 .. 10 )' loop,
as the change will be overwritten at the next loop iteration. If you really
need to modify the loop iterator, then you should use a C-style for loop:
for( my $i = 0; $i <=10; $i++ ) {
...
}
