I have a file in which I have 20 records. I want my first record to go into file 1 and second record to go in second file. I want to copy the alternate records like this in the two output files.

z/OS V1R11.0 DFSORT Application Programming Guide wrote:
SPLIT
Splits the output records one record at a time in rotation among the data sets of this OUTFIL group until all of the output records have been written. As a result, the records will be split as evenly as possible among all of the data sets in the group.
As an example, for an OUTFIL group with three data sets:
    the first OUTFIL data set in the group will receive records 1, 4, 7, and so on.
    the second OUTFIL data set in the group will receive records 2, 5, 8, and so on.
    the third OUTFIL data set in the group will receive records 3, 6, 9, and so on.

The records are not contiguous in each OUTFIL data set.
SPLIT is equivalent to SPLITBY=1.

For completeness, the DFSORT job would be:

Code:

//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=...  input file
//OUT1 DD DSN=...  output file1
//OUT2 DD DSN=...  output file2
//SYSIN DD *
  OPTION COPY
  OUTFIL SPLIT,FNAMES=(OUT1,OUT2)
