Help me through this, I'm getting confused. Here is my document: "The quick brown fox jumped over the |lazy dog." The position of the global cursor is indicated by '|'. Internally, I imagine that this cursor contains a (valid) PosIterator. I wish to find "brown": PosIterator pos = search_for(buffer, "brown"); I now wish to replace "brown" with "red". How do I do so to ensure that the global cursor remains valid? -- Angus
