On my tests with ksh the "" approach does not work.
Though exporting VAR_A makes the variable visible in the called script, the changed value of VAR_A is not available to the calling script .

I have certainly used the approach suggested by "chompy" and written results to a file and then read them back in the calling script.

If is normally silent there are a couple of ways of passing values back.

General solution where the reply is a word or a number

From | read REPLY

echo "whatever"

Another solution if the answer is a low number which is valid in "exit"

From ; REPLY=$?

exit $value
