try this method, This way you can forget about hard coding your numeric of "3" so you know where to stop on your loop.

This adds the ability to add as many dymanic vars as you want.

Enjoy!

# You can set the array in two ways
# Method 1
# hellos="hello1 hello2 hello3"
# set -A myvar $hellos

#Method two
# myvar[0]="hello1"
# myvar[1]="hello2"
# myvar[2]="hello3"

# if your useing only one array then use what you
# feel is best for you.
# Method two offerres the option of adding more arrays
# that have a direct association to each other
# for example:

myvar[0]="hello1" ; othervar[0]="Bob"
myvar[1]="hello2" ; othervar[1]="Joe"
myvar[2]="hello3" ; othervar[2]="Mary"


count=0

# by using the ${#myvar[*]} you can add as many
# "myvars" and "othervars" as you want with out
# the need to rememdber the modify the max counter
# thus knowing where to end your loop.

while [ $count -lt ${#myvar[*]} ]
do
echo "${myvar[${count}]} - ${othervar[${count}]}"
let count=$count+1
done

template::plugin::dumper

Template::Plugin::Dumper(3)				User Contributed Perl Documentation			       Template::Plugin::Dumper(3)

NAME

       Template::Plugin::Dumper - Plugin interface to Data::Dumper

SYNOPSIS

	   [% USE Dumper %]

	   [% Dumper.dump(variable) %]
	   [% Dumper.dump_html(variable) %]

DESCRIPTION

       This is a very simple Template Toolkit Plugin Interface to the Data::Dumper module.  A "Dumper" object will be instantiated via the
       following directive:

	   [% USE Dumper %]

       As a standard plugin, you can also specify its name in lower case:

	   [% USE dumper %]

       The "Data::Dumper" "Pad", "Indent" and "Varname" options are supported as constructor arguments to affect the output generated.	See
       Data::Dumper for further details.

	   [% USE dumper(Indent=0, Pad="<br>") %]

       These options can also be specified in lower case.

	   [% USE dumper(indent=0, pad="<br>") %]

METHODS

       There are two methods supported by the "Dumper" object.	Each will output into the template the contents of the variables passed to the
       object method.

   dump()
       Generates a raw text dump of the data structure(s) passed

	   [% USE Dumper %]
	   [% Dumper.dump(myvar) %]
	   [% Dumper.dump(myvar, yourvar) %]

   dump_html()
       Generates a dump of the data structures, as per dump(), but with the characters <, > and & converted to their equivalent HTML entities and
       newlines converted to <br>.

	   [% USE Dumper %]
	   [% Dumper.dump_html(myvar) %]
