It isn’t necessary to make a single-line awk script to embed it into a shell script. When you use single-quotes, it automatically handles multiple lines.

for ARG in "$@"
do
    postcode=`echo "$ARG" | sed -e 's/\(.*\)/\U\1/'`
    areacode=`echo "$postcode" | sed -e 's/.*\(^[A-Z][A-Z]*\).*/\1/' | sed -e 's/\(.*\)/\L\1/'`
    awk  -v pcode="\"""$postcode""\"" '
        BEGIN {FS = ","}
        {if (pcode == $1){ print $1", " $3", " $4 }}
    ' < "$areacode".csv 
done
