It will accept a list of begin-end position pairs which you can e.g. create from your positions with Partition as I have done below: StringTake[longstring, Partition[Flatten[{1, position, -1}], 2, 1]] > P.D.: I tried to use StringSplit first (without using the positions), but to > determine the positions I'm not only using patterns, so I didn't know how to > use that function for that. I think you should be able to use StringSplit, I wonder what you can achieve with StringPosition that you cannot with StringSplit. Note that StringSplit accepts arbitrary StringPatterns or RegularExpressions as a second argument... hth, albert
