question about getopts

question about getopts
hello there I am back with more questions (sorry it is been quite a while since I had done scripting). I had tried the search function to search for the threads that might have an answer to my question, but I could not find it, so I had decided to post it.
I had created the scripts below in ksh (assume the ksh file name is abc.ksh)
--------------------------------------------------------------------------
var1=' '
var2=' '
while getopts ":a
" opt
do
case $opt in
a) var1=$OPTARG;;
b) var2=$OPTARG;;
\?) echo "Invalid argument"; exit 1;;
esac
done
shift 'expr ${OPTIND} - 1'
echo "Statement"
--------------------------------------------------------------------------
I ran the codes
--------------------------------------------------------------------------
Server temp-> abc.ksh -a some_value -b other_value
--------------------------------------------------------------------------
It works perfect, but if I ran the code with out the command line option
--------------------------------------------------------------------------
Server temp-> abc.ksh some_value other_value
Statement
--------------------------------------------------------------------------
I thought if there are no -a or -b option is given, getopts would automatically faults out and abc.ksh would just display "Invalid Argument" and exit. Did I not doing this section of scripts correctly or I am just plain missing something?
Thank you for your time

stats_cdf_beta
STATS_CDF_BETA(3) 1 STATS_CDF_BETA(3) stats_cdf_beta - CDF function for BETA Distribution. Calculates any one parameter of the beta distribution given values for the others. SYNOPSIS
float stats_cdf_beta (float $par1, float $par2, float $par3, int $which) DESCRIPTION
Method Cumulative distribution function (P) is calculated directly by code associated with the following reference. DiDinato, A. R. and Morris, A. H. Algorithm 708: Significant Digit Computation of the Incomplete Beta Function Ratios. ACM Trans. Math. Softw. 18 (1993), 360-373. Computation of other parameters involve a search for a value that produces the desired value of P. The search relies on the mono- tonicity of P with the other parameter. Note The beta density is proportional to t^(A-1) * (1-t)^(B-1) Arguments P -- The integral from 0 to X of the chi-square distribution. Input range: [0, 1]. Q -- 1-P. Input range: [0, 1]. P + Q = 1.0. X -- Upper limit of integration of beta density. Input range: [0,1]. Search range: [0,1] Y -- 1-X. Input range: [0,1]. Search range: [0,1] X + Y = 1.0. A -- The first parame- ter of the beta density. Input range: (0, +infinity). Search range: [1D-100,1D100] B -- The second parameter of the beta density. Input range: (0, +infinity). Search range: [1D-100,1D100] STATUS -- 0 if calculation completed correctly -I if input parameter number I is out of range 1 if answer appears to be lower than lowest search bound 2 if answer appears to be higher than greatest search bound 3 if P + Q .ne. 1 4 if X + Y .ne. 1 BOUND -- Undefined if STATUS is 0 Bound exceeded by parameter number I if STATUS is negative. Lower search bound if STATUS is 1. Upper search bound if STATUS is 2. PARAMETERS
o $par1 - o $par2 - o $par3 - o $which - Integer indicating which of the next four argument values is to be calculated from the others. Legal range: 1..4 which = 1 : Calculate P and Q from X,Y,A and B which = 2 : Calculate X and Y from P,Q,A and B which = 3 : Calculate A from P,Q,X,Y and B which = 4 : Calculate B from P,Q,X,Y and A RETURN VALUES
STATUS -- 0 if calculation completed correctly -I if input parameter number I is out of range 1 if answer appears to be lower than lowest search bound 2 if answer appears to be higher than greatest search bound 3 if P + Q .ne. 1 4 if X + Y .ne. 1 PHP Documentation Group STATS_CDF_BETA(3)
