But the shifting is more expensive than the traversing :)

Yes, I understand it shifts everything, but you are not traversing deeper with each loop. You are only going 1 deep every time. Old school. :-) John -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of Wjhonson Sent: Tuesday, April 30, 2013 12:48 PM To: u2-users@listserver.u2ug.org Subject: Re: [U2] Help needed.. That's interesting John, but the del *does* in fact *shift* the entire array forward each time. It really does :) You can traverse without re-scanning by using the SELECT or SELECTV to transform the entire contents *once* into a type of Get List (it works try it!) You can then use a READNEXT to extract each row, without the need to rescan from the beginning, since READNEXT has always maintainted a pointer to where it left off. It doesn't start at the front each time. -----Original Message----- From: Israel, John R. <johnisr...@daytonsuperior.com> To: 'U2 Users List' <u2-users@listserver.u2ug.org> Sent: Tue, Apr 30, 2013 9:27 am Subject: Re: [U2] Help needed..

Hi all,.. I have a requirement here. Need guidance in doing that. Any help will be useful. TIA. I have a flat file with tab delimited records and the file looks like below: abcd 1234 cdef 3478 ghae 6284 ... I have to fetch the data 'abcd' and 'cdef' from this flat file and fetch some corresponding attributes from a file which has 'abcd' and 'cdef' as the key values. Please let me know if this could be done. If yes any kinda basic suggestions in doing that will be helpful.
