It is better to call it $SPACE:
my $SPACE = " ";

Or as some prefer:
$temp =~ s{ [ ]+ }{ }gx;
Or even:
$temp =~ s/\x20+/\x20/g;

Hi,
I have string that has one or more spaces. I would like to replace
them with a single space.
The simple code below replaces the spaces fine, but does not
substitute with a space.
$temp = "0 1 2 34"; <-> version 1
$temp =~ s/\s+/\s/g;
$temp = "0 1 2 34"; <-> version 2
$temp =~ s
