Once again, I just want what is in between first occurrence of "Services" and "Users".

I'm assuming that you aren't interested in the lines with the "======" stuff. Based on that, here's how I would approach the problem.

use strict;

my $file;
open(DATA,"<data.txt") || die "Unable to open file 'data.txt':  $!\n";
{
  local $/;
  $file = <DATA>;
}
close(DATA);
my ($selection) = ($file =~ m/^.+?Services.+?[=]+(.+?)[=]+/is);
my (@lines) = split /\n/,$selection;
for (my $i=0;$i<=$#lines;$i++) {
  $lines[$i] =~ s/\n//;
  print "Line $i:  $lines[$i]\n";
}

Which produces the following output:

Line 0:
Line 1:  blah
Line 2:  glah
Line 3:  sfsd
Line 4:
Line 5:
Line 6:  asfsdf
Line 7:  afsafdf

Although BrowserUK's code is probably better, the code above may be easier to follow for some folks (such as myself). Also, I should note that I do lose a blank line at the end of the captured section when I use the split command. Again, I'm assuming that won't create problems for what you're trying to do.

Anyways, this gives you an example of another approach to solving the problem.
