Using AS Perl 5.8.7 under W98SE, the PATH environment variable is
displayed, then assigned a new value; but the new value doesn't propagate
back to the MS-DOS %PATH% variable. Are the %ENV values read-only?
C:\Programs\PERL>SET
...
PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PERL\BIN\;C:\THINKPAD
...
C:\Programs\PERL>perl
print "$ENV{PATH}\n";
$ENV{PATH} = 'C:\WINDOWS;C:\WINDOWS\COMMAND';
print "$ENV{PATH}\n";
^D
C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PERL\BIN\;C:\THINKPAD
C:\WINDOWS;C:\WINDOWS\COMMAND
C:\Programs\PERL>SET
...
PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PERL\BIN\;C:\THINKPAD
...
