It seems like I'm missing something obvious to avoid the triple-pass
(although at least I'm only passing over the temporary page), but in any
event it works.

You can find the example at http://pmwiki.qdk.org/pmwiki.php?n=Test.LocCode,
as before.  Source is below my sig.

{(wikish source {$FullName}#test)}

(:if false:)
[[#test]]
grep '\(:location.*x=.*y=' Test.Loc? | sed -e 's/^/||/' -e 's/:\(:/||/' -e
's/ x=/||/' -e 's/ y=/||/' -e 's/:\).*$/||/' >Tmp.X

echo "!!Tmp.X"
cat Tmp.X

echo "!!page"
set i = 1
cat Tmp.X | cut -d'||' -f2 | while read foo
do
#echo "DEBUG: foo=${foo}"
   set -s page_${i} = ${foo}
   set i ++
done

echo "!!4"
set i = 1
cat Tmp.X | cut -d'||' -f4 | while read foo
do
#echo "DEBUG: foo=${foo}"
   set -s x_${i} = ${foo}
   set i ++
done

echo "!!5"
set i = 1
cat Tmp.X | cut -d'||' -f5 | while read foo
do
#echo "DEBUG: foo=${foo}"
   set -s y_${i} = ${foo}
   set i ++
done

for j in 1 2 3
do
   echo "* page=${page_${j}}, x=${x_${j}}, y=${y_${j}}"
done
