Hi 
 
You will define the variable the same way you declare an other variable
var myVariable = 'myValue';
To access it will need to references the frame where you did declare the
variable 
you said you have 3 frames named(examples) frame1, frame2, frame3
let say you declare the variable in frame1
if you want to access the variable in the frame one you do :
document.frame1.myVariable
if you are in a other frame you do exactly the same
document.frame1.myVariable
and this will give you the value of the variable if you want to change it
you do : document.frame1.myVariable = 'newValue';
 
hope this help? 
 
Laurent
