I find it easiest using file-aid
Go in FILEAID>UTILITIES>COPY specify i-o datasets and press enter.
In options give

Code:

                                                                           
 Subsequent Selection Interval:            then repeat the following       
   Records to select         ===> 1        - select this many records     
   Records to skip           ===> 0        - then skip this many records   
                                           until                           
 Number of records to search ===> ALL      you have read this many records
 Number of records to select ===>100    or selected this many records   
                                                                           
EQ/VSAM processing direction ===> B   (F = Forward; B = Backward)

Sortin the vsam file, use inrec to reformat a sequence number in front, sort on the sequence number decending, use outrec to format back to original record and stop after 100. you will need another sort to return to the original sequence if needed.
