Do you have something like closing prices in one container and shares traded in another container, each for the same 10,000 securities over the same 2,500 trading days? If so, do you want to calculate something like trading volume as price * shares? If so, then here's a way to bring together the values from one such list with the values from another, without waiting for any chunk expressions. On my machine, generating a 10,000 line by 2,500 item list of integers to prepare for the test took about three minutes. Then bringing together all the pairs of lines from two lists, as you indicated in your initial email, took about 1.2 seconds. So you could do many passes through your big lists before the day is done, and not need to wait for an extension to the language. To try it, paste the following into the script of a new stack. If I've misunderstood or done something wrong, please let me know. -- Dick --------------------- global gList on mouseUp if gList is empty then initialize combinePairsOfLines gList,gList end mouseUp on initialize put 10000 into tLineCount put 2500 into tItemCount put tLineCount && tItemCount & cr put the seconds into tSeconds repeat with i = 1 to tLineCount repeat with j = 1 to tItemCount put i + j & comma after tList end repeat put return after tList if i mod 1000 = 0 then put "line count so far:" && i & cr after msg end repeat put tList into gList -- save for reuse across edit-test cycles put "elapsed seconds to initialize:" && \ the seconds - tSeconds & cr after msg end initialize on combinePairsOfLines pList1,pList2 put the long seconds into tSeconds split pList2 using return put 0 into i repeat for each line tLineFromList1 in pList1 add 1 to i put tLineFromList1 & pList2[i] into tCombinedLine -- doSomethingWithCombinedLine tCombinedLine end repeat put "elapsed seconds to combine pairs:" && \ the long seconds - tSeconds & cr after msg end combinePairsOfLines _______________________________________________ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution
