Env module problem

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

We are trying to migrate from 5.003 to 5.8.7 on a Windows server. The following code produces different results depending on Perl version:

use Env;
$ENV{'MYVAR'} = '123';
$ENV{'myvar'} = '123';
Env::import;
print "\$MYVAR: $MYVAR\n"
    , "\$myvar: $myvar\n";

On Perl 5.003 it produces:

$MYVAR: 123
$myvar: 123
[download]

On Perl 5.8.7 it produces:

$MYVAR: 123
$myvar:
[download]

Can andyone suggest what is happening? We have a large amount of code that depends on both variables being set. (I didn't write this stuff!)

Windows environment variables are case-insensitive. Your 5.003 is buggy, and your 5.8.7 is corrent. `>set myvar=123 >set MYVAR=456 >echo %myvar% 456 >echo %MYVAR% 456` [download] Update: The bug has been fixed at least since `This is perl, v5.6.1 built for MSWin32-x86-multi-thread (with 1 registered patch, see perl -V for more detail) Copyright 1987-2001, Larry Wall Binary build 633 provided by ActiveState Corp. http://www.ActiveState. +com Built 21:33:05 Jun 17 2002` [download] I can't find any reference to it in the deltas, but it could be mentioned in the `Changes` file.

I get: `$MYVAR: 123 $myvar: 123` [download] on various versions from 5.6.0 to 5.8.8 on Linux, but I also see your unexpected output on Activestate 5.8.7 on Win2k.	[reply] [d/l]
