Wohoo, think I sorted the loop!

while (1) {
    my $page = get "$pbase?page=$pcnt&pid=$pid";
    last if $page =~/No sorties/;
    # Store grabbed webpage into the file
    append_file( "c:/scr/$pid.txt", $page ) ;
    last if $page =~/"sid=$lproc"/;
    # Update page number and grab next.
    $pcnt++; 
};

I'm sure the whole thing can be made prettier and more efficient, but now it seems to work as intended, grabbing the first set of data I need.

Now I need to sort the bit where it does the same for all pids in the pidlist, preferably at the same time adding so it extracts both the pid and lproc data from the settings file.
