It writes the first record and then skips a record and then writes the third record again, so basically were here writing the odd numbered records .i.e. when divided by 2 and the remainder is not equa...

Use Counter

Code
Read input file
 If not End-of-file
  Add 1 to ws-counter
  If ws-counter = 2
     write record to output file
     move 0 to ws-counter
  end-if
 end-if
end-read

Add a seq number to file thru JCL (1:seqnum,3,zd) and sort the file in descending order sortfields=copy, include cond=(1,3,zd,d) after this provide the file in Cobol as input.

Can be done in VSAM : by using Low and HIGH-VALUE
If you pass HIGH-VALUE to the key field, then it will read the record from bottom

Without compiling the program, is it possible to find whether it doesnt have errors? If Yes,
Could you please let me know what is the procedure you are following to find the errors?

Compilation converts the source code in to object code but the object code is not executable in mainframe environment so we need to link-edit it by using iewl............compilation is must for the programs to execute...............

Copy - Expand the copybook statements during compilation time.

Include - Expand the copybook statements during pre-compilation time. Usually for DELGENS we use INCLUDE as DCLGEN statements needed during pre-compilation process.

Copy will be used in the cobol compile process and Include will be used during the Db2 precompile process. So we include a Dclgen. We cannot copy a dclgen..If so the program will fail the compilation.We can include a copybook too.

For a clustered index DB2 maintains rows in the same sequence as the columns in the index for as long as there is free space. DB2 can then process that table in that order efficiently.

Clustered index is unique for any given table and we can have only one clustered index on a table. The leaf level of a clustered index is the actual data and the data is resorted in case of clustered index

Partitioned table is clustered by clustering index
