Thanks for that.  Will have a look at the man pages.

variables used and defined in functions are accessible only to that function - local

to use a global variable define it at the beginning
eg-
VAR1=""

you can also use a declare statement
to create an array -
declare -a VAR2

help declare
for more info

to write to a variable use it straight -
VAR1="some value"
VAR2[0]="some other value"

to access the values use a dollar sign in front {} gives more clarity and must be used 
with array variables.
echo $VAR1
echo ${VAR2[0]}

for more info on bash scripting do
man bash
or
info bash

this is one of the lengthiest man pages I've seen but it covers everything used in bash.
