in thread Using STDIN after exec() with ActiveState Perl

It should work exactly the same way 
use Module::Load;
... 
$ENV{SPRING_DATADIR} = ...;
load( "ModuleName" );

    On Linux it works, but not on Windows (I re-checked right now).

      I don't believe that :)

      You must be loading the module before you modify %ENV

      Don't do that, only load the module after you've set %ENV

        Here is the code for test.pl: 
        use warnings;
use strict;

use Module::Load;

if(! $ENV{SPRING_WRITEDIR}) {
  $ENV{SPRING_WRITEDIR}='E:\\test';
  exec {$^X} ($^X,$0);
}
$ENV{PATH}="E:\\springrts;$ENV{PATH}";
load("PerlUnitSync");

PerlUnitSync::Init(0,0);
my $writeDir=PerlUnitSync::GetWritableDataDirectory();
print "writeDir=$writeDir\n";

        Here is the output: 
        E:\test>perl test.pl

E:\test>writeDir=E:\test\

        [download]
        And now the output if I comment the exec line: 
        E:\test>perl test.pl
writeDir=D:\Documents\My Games\Spring\

        As you can see the SPRING_WRITEDIR environment variable is not taken into account if I don't use exec.
