You want to be able to validate any word in a space delimited list, not every byte, right?

You might change your input validation to a case string, somewhat more varsatile with | (or), [abc] (list of char) and such:

Code:

#!/usr/bin/ksh

valInp(){

for i in $1 qzzq
do
 bad_args=""

 case "$i"  in
 (qzzq)
   ;;
 ($2)
   ;;
 (*)
   bad_args="$bad_args $i"
   ;;
 esac
done

if [ "$bad_args" != "" ]
then
 return 1
fi
}

Using a grep -E regex-pattern would be even more powerful.

Code:

#!/usr/bin/ksh

valInp(){

bad_args=""

echo $1 | tr ' ' '\12' | grep -Ev "$2" | while read bad
do
 bad_args="$bad_args $bad"
done

if [ "$bad_args" != "" ]
then
 return 1
fi
}
