Display header in script output

Hi -- Working on my own through the book "Learning the KornShell and came to task 4-1, which there is:
a script "highest" and it will sort an "album" file.
highest filename

The author mentions adding a header line to the scripts output if the user types in the -h option. It says "assume the option ends up in the variable "header" i.e $header is -h"

If user runs the script with -h, it will produce a header on the output that reads "Album Artist" and a new line" if the -h option is not used there is no header or new line.

From the book:
The expression
${header:+"Albums Artist\n")
yields null if the variable header is null or "Albums Artist\n" is not null.
we can put the line:
print -n ${header:+"Albums Artist\n"}

My problem is i do not know how to make $header relate to the -h option. It says "assume....." but i want to follow along and run the script. Tried the man pages, but no luck. If you have any ideas please respond. Thanks.

vpl2mod.1

VPL2MOD.1(1)						      Sword Module Utilities						      VPL2MOD.1(1)

NAME

       vpl2mod - tool to convert verse per line source to SWORD module

SYNOPSIS

       vpl2mod SOURCE PATH [0|1] [0|1]

DESCRIPTION

       This utility is used to create SWORD module from the verse per line formated source. The resulting module will be saved in the path
       specified.

OPTIONS

       [0|1] [0|1]
	   The first option indicates whether to prepend verse references or not.  The second option is to indicate whether module is NT only or
	   not.

NOTE

       With no verse references source file must contain exactly 31102 lines. This is KJV verse count plus heading for the module, testament, book
       and chapter. An example snippet follows:

	MODULE HEADER
	OLD TESTAMENT HEADER
	GENESIS HEADER
	CHAPTER 1 HEADER
	In the beginning...

       This example implies there must also be a chapter 2 header, Exodus header, New Testament header, etc. If there is no text for the header, a
       black line must, at least, hold place.

       With verse references, source file must simply contain any number of lines, that begin with the verse reference for which it is an entry,
       e.g.:

	gen 1:0 CHPATER 1 HEADER
	get 1:1 In the beginning...
