how to concatenate datasets

Answer / pkb
It is possible to process more than one data set as a single data set by concatenating the DD statements.
//QSAM0080 DD DSN=SIMOTIME.DATA.FILE0001,DISP=SHR
// DD DSN=SIMOTIME.DATA.FILE0002,DISP=SHR
// DD DSN=SIMOTIME.DATA.FILE0003,DISP=SHR
The following is an example of a COBOL SELECT statement.
here the COBOL program will read QSAM0080 and the DD statements will map the three files (FILE0001, FILE0002 and FILE0003) as one file. The program's initial read will get the first record from FILE0001 and will not get an End-of-File condition until the last record of FILE0003 is processed.

Answer / suputhru
concatenation is possible up to 16 pds or 255 ps
We can cancatinating diffent files by giving their DSN one after other, all the datasets must be same type.
rules: there should be logical record length must be same
and type recfm is also same
//jobcard
//step1 exec pgm=concat11
//ddname DD dsn=tst.punna.cobol,
// DD dsn=tst.punna.cobol1,
// DD dsn=tst.punna.cobol11,
// DD dsn=tst.punna.cobol211,

Answer / chowdary
concatenation is possible up to 16 pds or 255 ps
rules: there should be logical record length must be same
and type recfm is also same
//jobcard
//joblib
//dd dsn=tst.punna.cobol,
dsn=tst.punna.cobol1,
like that we need to give up to our requirement

Answer / shankar
we can also concatenate through disp keyword parameter also..
use iebcopy utility and
sysut1 dd dsn=sample1.pds,disp=(old,pass)
sysut2 dd dsn=sample2.pds,disp=(shr)
sysin dd *
copy indd=sysut1 outdd=sysut2
