Bernd, The REXX processing after sort is not as much a transformation as it is a search for the next available value from an IP block.

Should be a piece of cake ... Then the sort ... and if the leading zeroes indeed need to be removed again, you can do this in the REXX routine which runs after the sort. If the file is not very large, even the sorting can be done by clever usage of a REXX stem variable ... put the whole thing in a REXX stem, do all the modifications and sorting there and put it out in the desired format and order. I've done this very often even on Windows, to get readable reports out of unstructured test data ... BTW: 35th birthday of REXX some days ago ... many thanks to Mike Cowlishaw !
