Who ever gave you homework is silly... ;-D >I want to copy position 31 to 40 of all records but from record 8 and 9 I >want to copy also (concatenate) position 71 to 80 and from record 6 to 8 I >also (concatenate in "front") want to copy position 1 to 3. Hmmm. Hard requirement if you want all of this in ONE pass. Could you be kind to post an example of your input and output? What about the rest of input? Should they stay the same during copy or left out of the output? >I can see the use of the SUBSET (ICETOOL) for record selection but how do you >user DFSORT/ICETOOL to solve the combining record and varying position needs ?

Could you post that program or some snippets? I believe I could do that with REXX.
