See the "Keep the last n records" Smart DFSORT Trick at:

www.ibm.com/systems/support/storage/software/sort/mvs/tricks/

Just adjust the count value to be 1 records instead of n records.

You can do this kind of thing quite easily using the new SUBSET operator of DFSORT's ICETOOL available with z/OS DFSORT V1R5 PTF UK90013 (July, 2008) like this:

Code:

//S1  EXEC  PGM=ICETOOL                                           
//TOOLMSG   DD  SYSOUT=*                                           
//DFSMSG    DD  SYSOUT=*                                           
//IN DD DSN=...  input file                                       
//OUT DD DSN=...  output file         
//TOOLIN DD *                                                     
SUBSET FROM(IN) TO(OUT) KEEP INPUT LAST
/*     


For complete details on the new SUBSET function and the other new functions available with PTF UK90013, see:
