Here's a simple example script:

myfunc(){
echo "#=$#, 1=$1, 2=$2, 3=$3, 4=$4, 5=$5"
}
parm1=parm1
parm2="this is parm2"
parm3=parm3
parm4="words for parm4"
args="$parm1 $parm2 $parm3 $parm4"
myfunc $parm1 "$parm2" $parm3 "$parm4"
myfunc $args

I need to invoke myfunc in the second manner and achieve the same result as
the first invocation.
