That's amazing.
It worked the first time around. I really appreciate your help on this.
If you could answer a qusetion... I'm having trouble finding a tutorial or information on the "l - 13" or "l - 9" portion of the code.
I read the man on awk for substr (which is vague and confusing) and I'm just curious how I can make myself fluent in this language without having to pull my hair out and ask a billion questions.... If you could give me some insight on that, I'd really appreciate it.

I KIND OF understand what it's saying but not quite.
substr($1, l - 13, 4)
The above looks like it's starting the count, 4 from the end, 13 to the left, which goes over 2012.
substr($1, l - 9, 2)
The above starts the count 2 from the end, 9 to the left, which is right between the 2012 and 12, which seems perfect. Am I missing something here? (obviously I am.)

IGAWK(1) Utility Commands IGAWK(1)
NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
