[REBOL] Re: Find? Copy/Part?

From: carlos:lorenz:gmai:l at: 18-Jan-2005 15:05

Ingo, Thanks for you reply. I dir not think about parse though I can see you solve it using it. Parse yet has a not so confortable sintax to me so I try to avoid the use of it most part of the time. I'd like to have something just like I get in Visual Fox Pro. See below: * ------------------------------------------ a = "aaa*aaa*aaa*aaa" * gets the second ocurrence of "*" in the string from left to right pos = at( "*" , a , 2) * then asking VFP to grab a piece of the string up to the * second "*" in the string a ? left(a,pos) * gives the result aaa*aaa* * ------------------------------------------- Would it be very nice to have an AT-like native function in REBOL/Core, don't you think so?
