This should do it. The code looks odd, I know. But it will run pretty quickly.
Code:
#! /usr/bin/ksh
integer errors
errors=0
IFS=""
while read inputline ; do
        line="${inputline%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%\|*([!|])}"
        line="${line%%*([!|])}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line#*([!|])\|}"
        line="${line##*([!|])}"
        if [[ "$line" != \|*([!|@])@*([!|@])\| ]] ; then
                echo error: "$inputline" 
                ((errors=errors+1))
        fi
done
((errors)) && echo $errors total errors
exit $(($errors!=0))
