Parsing input paramter in a script
Hi folks I am having a little trouble in parsing a variable read into a ksh script

I have a bunch of variables passed into script

test.ksh HOST SERVER JOB1 JOB2 JOB3 JOB4 JOB5

What I want to do is read all the $JOB variables ($JOB1, $JOB2, $JOB3) into a variable and then read that variable in a loop and use the values in a case statement for further use however when I try doing this

if [ $# -lt 3 ]
then
echo
usage()
echo
exit
fi

J=$3,$4,$5,$6,$7,$8
for JOB in $J
do
case $JOB in
BUPD ) echo $JOB ;;
FUPD ) echo $JOB ;;
DMMD ) echo $JOB ;;
BNMD ) echo $JOB ;;
OC10 ) echo $JOB ;;
WRPF ) echo $JOB ;;
STRT ) echo $JOB ;;
CKPS ) echo $JOB ;;
CKRT ) echo $JOB ;;
esac
done

This however is reading all the variables in one

echo $JOB is returing BUPD,FUPD,DMMD,BNMD,OC10,STRT

Can someone help

sdisna

sdisna.f(3)							      LAPACK							       sdisna.f(3)

NAME

       sdisna.f -

SYNOPSIS

   Functions/Subroutines
       subroutine sdisna (JOB, M, N, D, SEP, INFO)
	   SDISNA

Function/Subroutine Documentation
   subroutine sdisna (characterJOB, integerM, integerN, real, dimension( * )D, real, dimension( * )SEP, integerINFO)
       SDISNA

       Purpose:

	    SDISNA computes the reciprocal condition numbers for the eigenvectors
	    of a real symmetric or complex Hermitian matrix or for the left or
	    right singular vectors of a general m-by-n matrix. The reciprocal
	    condition number is the 'gap' between the corresponding eigenvalue or
	    singular value and the nearest other one.

	    The bound on the error, measured by angle in radians, in the I-th
	    computed vector is given by

		   SLAMCH( 'E' ) * ( ANORM / SEP( I ) )

	    where ANORM = 2-norm(A) = max( abs( D(j) ) ).  SEP(I) is not allowed
	    to be smaller than SLAMCH( 'E' )*ANORM in order to limit the size of
	    the error bound.

	    SDISNA may also be used to compute error bounds for eigenvectors of
	    the generalized symmetric definite eigenproblem.

       Parameters:
	   JOB

		     JOB is CHARACTER*1
		     Specifies for which problem the reciprocal condition numbers
		     should be computed:
		     = 'E':  the eigenvectors of a symmetric/Hermitian matrix;
		     = 'L':  the left singular vectors of a general matrix;
		     = 'R':  the right singular vectors of a general matrix.

	   M

		     M is INTEGER
		     The number of rows of the matrix. M >= 0.

	   N

		     N is INTEGER
		     If JOB = 'L' or 'R', the number of columns of the matrix,
		     in which case N >= 0. Ignored if JOB = 'E'.

	   D

		     D is REAL array, dimension (M) if JOB = 'E'
					 dimension (min(M,N)) if JOB = 'L' or 'R'
		     The eigenvalues (if JOB = 'E') or singular values (if JOB =
		     'L' or 'R') of the matrix, in either increasing or decreasing
		     order. If singular values, they must be non-negative.

	   SEP

		     SEP is REAL array, dimension (M) if JOB = 'E'
					  dimension (min(M,N)) if JOB = 'L' or 'R'
		     The reciprocal condition numbers of the vectors.

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit.
		     < 0:  if INFO = -i, the i-th argument had an illegal value.
