in reply to Survey file parsing

In case no header line starts with whitespace followed by "<", but the first non-header line does, a simple solution would be as follows. (Maybe I misunderstood your notation, and the lines do not really start that way, but then either the must be identifiable using another regex or you must resort to counting lines.)
my $in_header++; while (<IN>) { if ($in_header && !/^\s+</) { push(@hdr, $_); } else { $in_header = 0; #process non-header lines (if needed) #... } }

    For the SEG-P1 format specification, all non-header lines (read: data lines) start with a space. That zero-offset position is reserved for identifying header lines.
