I'm comfortable with csh. However, i need to run a ksh script.Using exec /bin/ksh -i , I'm able to invoke ksh, but the script is not running any further. Variable QDDTS is an env setting on my csh env.
The ksh script goes like this -

#!/bin/csh

exec /usr/local/bin/ksh -i

function prepbuglist
{
print "Running prepreport "$1 $startday $today

$QDDTS/bin/query.pl "Project:ABC and Product:xyz and Severity:1,2,3,4,5" > /tmp/all-rn.bugs
