Hi,
We have a configuration file from which we need to read and set some environment variables 

if(open IPFH,"<$fname")
            {
              seek IPFH,0,0;
              while (! eof IPFH)
               {
                my $con=<IPFH>;
                chomp $con;
                my($variable,$value)=split '=',$con;
                chomp $variable;
                chomp $value;
                $ENV{"$variable"}=$value;
            
             }

The issue is that Environment variables are not being set when we do this way; however when we explicitly specify like this $ENV{'HOSTS'}=$value; it works.Is there a way to overcome this.

Thanks in advance Robby

Im new to perl.... I guess my earler posting was not clear...
Heres what I tried
test1.pl....
 my $value='abcdef';
$ENV{'PLATFORM'}=$value;
###### I belive this should set the environment variable PLATFORM

#just to confirm I called another perl program from with in this so if the environment is set then it should be reflected in the called program.
my $res=`perl c:/temp/test2.pl`;
print"\n result from test2.pl == $res\n";

test2.pl.....
 my $val=$ENV{'PLATFORM'};
print "\n value of envir var platform= $val\n";
####### I belive this should now give abcdef

RESULTS:
#when test1.pl was run
result from test2.pl == value of envir var platform= abcdef

#### Thus I belive that the environment variables are actually set with in the life time of perl program test1.pl... please correct me if iam wrong.

########## Now my question ############
I need to do a similar stuff but the problem is that the environment variables which need to be set are available in a configuration file which needs to be read and then set, I tried to use a code as given in my earlier posting; however the problem was that when ever I use

$ENV{"$variable"}="$value"; # not thing seems to be happening

$ENV{'PLATFORM'}="$value" ; # This seem to work

please advice...

Thanks Robby
