in reply to How to get into $ENV{'QUERY_STRING'}?

Your code isn't going to compile. You have an extra } hanging out, and you have a boolean comparison in there, but nothing is using it. (thats the eq function). I didn't see any environment variable stuff in your first script, so I'm not sure where you are getting the variable from. Remember that the %ENV hash is provided to a script from the parent process, and any alterations that you make to it are local. The changes don't affect the parent, only the children. 
#!/usr/local/bin/perl
use CGI qw(:standard);
@jid = param('JobID');
  
print "Content-type: text/html\n\n";
print "<head><title>TEST SCRIPT</title>";
print "</head><font size=2 face=arial><p>";

foreach $jid (@jid) 
{
    print "+$jid";
}
$ENV{'QUERY_STRING'} eq (print "+$jid");
#$ENV{'QUERY_STRING'} = print "+$jid";
