Can you explain what you're trying to do? You want to open a handle in a condition, then use the handle globally elsewhere. What if you don't open the file? Do you have code like this?
if (...){
open FH, '>', $file or die $!;
}
...
if (...){
print FH ...;
}
...
if (...){
print FH ...;
}
In other words, if the 'Example' if wasn't true, that file won't be open, and every call to the handle will need to be wrapped in a conditional as well.
Understanding what you're trying to do overall will help us help you sort out your logic.
