[REBOL] Re: Series manipulation Help

Then I'd apply the following hack: lst: ["Charlie" 11111 "Peter" 239823 "Sam" 11111 "Tiana" 92348] target: "Sam" target-id: select lst target if not none? target-id [ remove at lst 1 + index? find lst target alter lst target append lst target append lst target-id ] This code is "inefficient" in that in searches lst three times (select + find + alter). You could attempt to "optimise" it by saving the initial position in a variable. But unless you are intending to execute it a zillion times a day on megabyte long blocks, it's hardly worth the effort. Should work if you have duplicate target-ids and/or duplicate targets (more than one "sam"). Likely to go astray if a target can be the same as a target-id (not currently a problem as they are in different domains -- string! vs number!) Sunanda.
