explain concatinating datasets?
Answer / ravi
In JCL , we can concatenate different files by giving their
name one after another. All data sets concated must be of
the same type. For example,
1)partitioned data sets can be concatenated only with
partitioned data sets.
2)Record format should be same
3) All the files should on same device (like DASD, Tape)
4) File having largest BLKSIZE should be mentioned first
Maximum of 255 sequential data sets can be concatenated
Maximum of 16 partitioned data sets can be concatenated
Example JCL --> //MYJOB JOB (W345),'XXX'
//STEP1 EXEC PGM=COBPROG
//INFILE DD DSN=TEST.GLOB.FILE1
// DSN=TEST.GLOB.FILE2
// DSN=TEST.GLOB.FILE3
In program , we will read it as an single file.
concatination of three files done by operating system.
