    I was wondering if there's a way to break up a list so that all the items of the list that have the same first four characters are processed as a sub list.
    The list is already sorted so that all the items that have the same first four numbers are together.

    Sample list:

    8293 58536 03 01 M361290 11/17/04 1800PS
    8293 60076 03 01 M361290 11/17/04 1800PS
    8293 60485 03 01 M361290 11/17/04 1800PS
    8293 60609 03 01 M361290 11/17/04 1800PS
    8293 60610 03 01 M361290 11/17/04 1800PS
    8293 60638 03 01 M361290 11/17/04 1800PS

    8118 58753 03 01 M361100 11/17/04 1800SE,IFS

    I want :
    8293 58536 03 01 M361290 11/17/04 1800PS

    8293 66131 03 01 M361290 11/17/04 1800PS

    as a sub list to process during a loop.

    TIA

    Something like this?
    Note: The list needs to be sorted list, as what is in your sample.

    ;;;(setq lst '("8293 58536 03 01 M361290 11/17/04 1800PS"

    That works.

    I was thinking there would be a VL and lambda thingy out there, but maybe not.

    Thanks

    Hi Bill, I think massoc will help (at least in part) with this. I don't
    have it, but I've seen it posted here a few times.

    of the list that have the same first four characters are processed as a sub
    list.

    I do believe you're right about that.

    I have it right here to try it out.

    Thanks

    That works for the first sub list.

    Code:
    (defun breaklist (key alist)
    (apply 'append
    (mapcar '(lambda (x)
    (if (eq (substr x 1 4) key)
    (list x)
    )
    )
    alist
    )
    )
    )
    
    Now I have to figure out how to remove the sublist from the test list for the next loop.

    First sublist:
    Code:
    ("8895 26960 05 01 M361930 11/17/04 1700 FISH" "8895 28719 05 01 M361930
    11/17/04 1700 FISH" "8895 34228 05 01 M361930 11/17/04 1700 FISH" "8895 37502

    "8895 38906 05 01 M361930 11/17/04 1700 FISH" "8895 38925 05 01 M361930

    11/17/04 1700 FISH" "8895 77451 05 01 M361930 11/17/04 1700 FISH")
    
    Any ideas?

    I think I got it now.

    (while (setq lt (breaklist (nth cnt xx) x))(do whatever here)(setq cnt (+ (length lt) cnt)))

    Thanks to all that helped.

    Here's the final version that seems to work the best, using one list.

    (setq cnt 0
    )
    (while (< cnt (length lt1)) ;(main loop.)
    (setq key (substr (nth cnt lt1) 1 4)
    tmplst (breaklist key lt1))

    ;;;do whatever to each sub list here.

    ) ;end while
