Quickest was to compare 2 CR lists?

[Klaus Major]

Hi all,

anyone knows the quickest ways to compare 2 CR delimited lists?
I need to know what lines of list 1 are contained in list 2.

Right now I am using repeat "for each" and "lineoffset", which is fast,
but I'm ure this can be done even faster :-)

List 1 = k1
List 2 = k2

...
   repeat for each line i in k1
     if lineoffset(i,k2) <> 0 then
       put i & CR after new_ list
     end if
   end repeat
delete char -1 of new_ list
return new_ list
...


Best
