Hi!
I got your mail from the Perl-malinglist. You have to unscribe from that
list manually yourself.
Best regards

Hi again!
I've been looking around...
And one thing I don't get. You tell me that > SOMEVAR will be available to
you in your program and any programs you spawn( with 'system' or
backtics). But after your perl script ends, SOMEVAR is lost) and this
seems to be correct when I test my program, but I get confused when I read
about it on the net...

If I like to set an environmentvariable permanently from my program?
Isn't that possible in Perl?
