texte = I'm not trying to remove every instance, I'm just trying to find them, one at a time, inside the loop ... and middle is the correct tool for this purpose. I'm just surprised to get "000" rather than a blank/empty value after the final "abc" has been removed from the 'ts' value, that's all. If this is not a bug then maybe middle has always worked like this. I just figured that it started looking for the match string beginning with the first character of the 'ts' value, and then it ignored every character it had already looked at -- until it either found the match string or failed to find it. Either way, I thought it would return only the chars that had not yet been looked at ... but that's apparently not the case.
