Hey zee3b, I figured I'd respond to your PM here so I'd have more room.
Hey, thanks a lot for the help. That really worked and was exactly what I was looking for. When you get a few mins, can you please explain how the code works for my understanding. Thanks! 
# Read through file/data one line at a time.
while (<DATA>) {

    # Remove newline from end of line (actually not necessary for your
+ input).
    chomp;

    # If a line ends with '{', use a regular expression (REGEX) to cap
+ture
    # the relevant portion by having that portion surrounded by parent
+heses.
    # Push the captured string (contained within the variable '$1', si
+nce it
    # is the first captured string) onto the end of the array '@curren
+t command'.
    # This REGEX matches:
        # the beginning of the line: ^
        # 0 or more spaces: \s*
        # 1 or more of anything (captured because it is in parentheses
+): (.+)
        # 1 space followed by 1 {: \s{
        # the end of the line: $
    push @current_command, $1 if /^\s*(.+)\s{$/;

    # If a line ends with ';', use a REGEX to capture the relevant por
+tion,
    # then print out the contents of the array followed by the string 
+you
    # just captured and assigned to '$last_term'.
    if (/^\s*(.+);$/) {
        my $last_term = $1;
        say "set @current_command $last_term";
    }

    # If a line ends with '}', that means we are moving up a level, so
+ you
    # remove the last element of the array '@current_command'.
    pop @current_command if /}$/;
}
