Thanks for your explanation and the reference to perldoc, I understand now. But
it doesn't work yet, I still get the same error. I have altered my source now
as follows:
my %stp_dirs = ( "mvb" => "\%mvb_dirs",
"pkv" => "\%pkv_dirs",
"av" => "\%av_dirs",
"be" => "\%be_dirs",
"vvw" => "\%vvw_dirs" );
[...]
my ($sdir, $tdir);
while (($sdir,$tdir) = each %{$stp_dirs{$stp}}) {
DEBUG("SourceDir: $sdir\t\tTargetDir: $tdir\n");
}
Did I misunderstand anything?
Cheers,
Nora
