While this is absolutely correct there is a somewhat sophisticated trick by which it is possible to do the same in ksh88:

Code:

function caller {
typeset achArray[1]="foo"
typeset achArray[2]="bar"

callee achArray

return 0
}

function callee {
typeset -i iCnt=1

while [ $iCnt -le $(eval print \${#$1[*]}) ] ; do
    print - $(eval print - \${$1[$iCnt]})
done

return 0
}

Just in case it needs mentioning: possibility does not imply advisability. As the code above contradicts encapsulation (callee() uses variables that are silently inherited from caller() ) i wouldn't resort to such methods if there is any other and simpler way to do it. Sometimes, though, you just have no choice other than to be tricky.

I hope this helps.
