Returning string values from a bash function

Hello,

I need to know how to return a string value from a bash function. I 
tried using "return $VariableName", and got the error that return 
expected a numeric value.

So far I have been just operating on a variable declared before the 
function call from within the function, i.e. global in scope to the 
function itself, and that works, but I would like to know if I can 
return the value of a variable that is local the the function.

In other words I would like to be able to make a call like the 
following, and have it work.

SomeVariable=`MyFunction $Argument1`

or

SomeVariable=$( MyFunction $Argument1 )

Is this possible in bash?

Thanks, Ray Parrish
