According to the UniData Help for REMOVE, in the code sample above, DUM would be set to the first string delimited by a standard delimiter (e.g., @AM, @VM), and MORE would be set to index the level of the delimiter encountered: 0=End of array, 1=Record Mark (255), [EMAIL PROTECTED] (254), [EMAIL PROTECTED] (253), etc. A pointer is maintained so that the next REMOVE X FROM K would return the next string. The comment is stating that the "K = K" is used to reset the REMOVE pointer to the beginning of the string. Further info on using REMOVE: REMOVE is useful for sequentially processing all the elements of a dynamic array without having to "recount" for each subsequent item. However, you need to check your delimiters to find attributes/values/subvalues. A similar method to process each attribute is to SELECT K TO KLIST and then READNEXT DUM FROM KLIST within a loop. --Tom Pellitieri Century Equipment Toledo, Ohio ------- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
