I wasn't aware this only applied to STDOUT. My log messages all
appear at once, when the script has exited and I was hoping for some
'realtime' messages.

In other words, $log needs to be a global variable, so that it's

The method is below.
The idea is to enter this method feeding it a file name and
beginning directory and then looking for all occasions of
$file_name and push those addresses into @a_files. This works fine

I am trying to understand the correct way to define
variables and their scope.
Here are two simple PERL ( test1.pl and test2.pl
)scripts. test1.pl work fine, while test2.pl does not.
Would appreciate any help in understanding why
test2.pl is complaining about "Global symbols"

so has the effect of documenting your intent to use a global variable
to anyone who reads the code.
If you have multiple variables you want to declare, separate them by spaces:

i suggest you always
Try putting a "my" (without quotes) before the variable. What that will do is
to make it global so any function as well as the main part of your code will
be able to access it (then you won't need to put it within sub addEmail).
Sometimes though, you want only the function to be able to access a
