Re: Interpolate variable in a __DATA__ block

I'm trying to get a script to interpolate variable values in a
__DATA__ block if possible. This is a kind of alternative to a full-
blown template method. I'm not sure if I can even do what I want,
hence my posting here.

It can be done; see the FAQ entry

perldoc -q "expand variables"

<snip>

while (<DATA>)
{
chomp;
if ($_ eq "<$data>")
{
next;
print "$_\n";
}
if ($_ eq "</$data>")
{
last;
}
print "$_\n";
}

Try to replace that with:

while (<DATA>) {
chomp;
next if $_ eq "<$data>";
last if $_ eq "</$data>";
s/(\$\$\w+)/$1/eeg;
print "$_\n";
}
