If truly must have a digit to start with to do other processing,
then you could do:
#one form could be:
if ( ! /^\d/ ) {
# print the headers
}else {
# do other processing
}
# or another form:
if ( ! /^\d/ ) {
print ....
next;
}
# do the other processing and print
Wags ;)

Hello again...
I am reading in a file. There is a header of a varying number of lines.
All the header lines start with non-digits. I want to write them right back
out, untouched. All the others get crunched. I haven't been able to get
past the header. I will include samples of both below.
Thanks for your help.

{
open (INDATA, "$sonfile") ||die "cannot open $sonfile $!\n";
open (OUTDATA, "> $result") ||die "cannot open $result $!\n";
while (($line=<INDATA>))
{
chomp($line);
#
# Need to print the line back out if
# it doesn't start with a digit.
#
# Haven't figured out yet...
#
@_ = ($count, $hour, $minute, $second, $frame,
$hourb, $minuteb, $secondb, $frameb, $tiff)
= split(/[: ]/,$line);
# snip ..
# do stuff to data... works fine
# snip ...
}
close (OUTDATA);
close (INDATA);
}
