I need to run several programs that depend on Environmental Variables (found in %ENV) in a row. I need to set various values in %ENV that is passed to these programs that I am running using backticks (to catch the output). I would like to do this so that the %ENV changes are only local to the script being run at the time and not actually change the ENV values present.

I tried this:

print "$ENV{'TERM'}\n";
{
    $ENV{'TERM'} = "foo";
    print "$ENV{'TERM'}\n";
}
print "$ENV{'TERM'}\n";
[download]

the result should be:

vt100
foo
vt100
[download]

but it was this instead:

vt100
foo
foo
[download]

When this program was done the actual value of TERM was not changed when i checked from a commandline. Is there a better way to set ENV variables for programs being run from a perl script?
