Hi Dick,
Kudos!
As Sarah pointed it out, I was surprised to find out that putting the
fields into some variables first did not speed up the things as I
would have thought.
Good to know.
Let us think array :-)

Here's a solution that takes 10 milliseconds on a 1GHz PowerBook G4.
The main reason for the speed improvement over previous solutions
is that
array look-ups are typically faster than string searches.
put the milliseconds into tMilliseconds
repeat for each line tSymbol in field 2
put "true" into tSymbolArray[tSymbol]
end repeat
repeat for each word tWord in field 1
if tSymbolArray[char 1 to 2 of tWord] then
if tSymbolArray[char 3 to 4 of tWord] then
if tSymbolArray[char 5 to 6 of tWord] then
if tSymbolArray[char 7 to 8 of tWord] then
if tSymbolArray[char 9 to 10 of tWord] then
put tWord & return after tHits
end if
end if
end if
end if
end if
end repeat
put the milliseconds - tMilliseconds \
into tElapsedMilliseconds
put number of lines in tHits && "hits in" \
&& tElapsedMilliseconds && "milliseconds" \
& return & return & tHits
