RETURN variable

[jestrada101]

Is there a method to return a variable when a function is called? something like the following?

functionA()
{
(( a=100 + $1 ))

return a

}


tmp_a=`functionA 100`

-------------------------------------------
I'd like to store the returned "200" value into "tmp_a".

Thanks for any advice...

functionA()
{
(( a=100 + $1 ))

echo $a

}


tmp_a=`functionA 100`

Or just create a global variable.

function add() {
num=$1
add=$2
    num=`eval expr $num + $add`
export num
}

add 12 34 ; echo $num
46
add 32 31 ; echo $num
63
