[MacPerl] BBEdit 5.1/MacPerl and STDOUT

[WAMerrill@aol.com]

I ran across something with BBEdit 5.1/MacPerl the other day.  I sent an 
email to Bare Bones and today got a response.  My apologies if this has 
already been posted, but if not, it might save others some time trying to 
figure out what's going on.

Regards,

Here's my email and Bare Bone's response embedded within:

It just works that way.

Yes, this is purely a behaviour of BBEdit's particular Perl integration.
If you run a perl script without first clearling STDOUT, the output of the
script will be appended to the content of STDOUT. If you happen to save
the STDOUT file then new STDOUT windows will open with the saved content
plus any new output.
