Loop with multiple delimited variables
hi,

i need a portion in a audit logging shell script where i have to loop thru multiple variables.
I need some help in accomplishing this. i have 3 variables
Code:
var1=1,23,234
var2=a,ab,xyz
var3=0,0,0

the variables will have variables number of values but same length.(3 in this case )

i need to be able to loop thru values in var1 and get the values of all the variables to execute some commands.

Code:
while IFS=',' read var1 var2 var2
do
  echo "$var1 1 st value   $var2   first value   $var3 first value"

so for 1 st loop for var1 1 i need to use 1 ,a and 0 in a insert script to some tables. so they need to avaliable in 3 different variables so i can do
insert into table values ($var1, $var2, $var3)

in this case i will get
Code:
insert into table (1,'a',0)
insert into table (23,'ab',0)
insert into table 234,'xyz',0)

thanks in advance for some help

Excel::Template::Container::Loop(3pm)			User Contributed Perl Documentation		     Excel::Template::Container::Loop(3pm)

NAME

       Excel::Template::Container::Loop - Excel::Template::Container::Loop

PURPOSE

       To provide looping

NODE NAME

       LOOP

INHERITANCE

       Excel::Template::Container

ATTRIBUTES

       o   NAME

	   This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each
	   iteration.

CHILDREN

       None

EFFECTS

       None

DEPENDENCIES

       None

USAGE

	 <loop name="LOOPY">
	   ... Children here ...
	 </loop>

       In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array
       would expose a different hash of parameters to the children.

       These loops work just like HTML::Template's loops. (I promise I'll give more info here!)

       There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly
       acceptable. You can also hide outside variables with inner values, if you desire, just like Perl.
