Redirect output to file in subdirectory

I have a problem with a perl script that should redirect output to a certain file in a certain directory. The problematic line is
system "echo teststring >$testdir\\log.txt";

This is running on Windows 2000.

Changing the line to just
system "echo teststring >log.txt";
works fine, but when a subdirectory is specified, the file is never created and I don't get any output at all.

what is in $testdir, and how was it set?

Sorry, I should have said that from the beginning.
The value of $testdir doesn't seem to matter. Even if I do

system "echo teststring >Test\\log.txt";

I get the same error (no output, no file is created). In this case, Test is an existing subdirectory of the directory from where I call the perl script.

If I make the same call at a command prompt (echo teststring >Test\\log.txt) I get the desired result.
did you try
system "echo teststring >Test\\\\log.txt";
Why not just do it in Perl, eg:

open LOG, ">Test/log.txt" or die "Can not write to Test/log.txt $!\n";
print LOG "teststring\n";
close LOG;

Open in new window
