Datasets must be of the same type (disk or tape), All
datasets must have the same logical record length, The
dataset with the largest blocksize must be listed first.

Answer / sandy lofton
1. The dataset with the largest blocksize must be listed
first.
2. If concatenated datasets are libraries and contain same
name members, the first one found will be used.
3. Order is important: Disk first, tape second, cards
third.

Answer / muttaiah
1) The dataset should be of same type meaning if you are
concatenating a PDS then other ds should be pds only & ps-
Ps)
2) They should have same format and LRECL
3) If the dataset's have diff blocksize then the dataset
with Largest block size should be coded first
4) All the datasets should reside on the same unit(device).
however the volume serial number can differ
5) we can concatenate 16 PDS & 255 PS files

with out sorting how to copy records from one file to another file using jcl.Mean I have one input file in which the record are like 1,6,5,4,2,3(for example) and i want to copy to output file from top to bottom(without sorting) like 3,2,4,5,6,1.so I want the JCL for this.cna any one can answers?
In a single step if input file is present then only need to copy into output file or else need to through a RC is it possible. Note : i want it in a single step
i have job card like this //job ***** //step1 exec pgm=iebgener //sysut1 dd dsn=main.sss,disp=shr // dd dsn=main1.sss,disp=shr // dd dsn=main2.sss,disp=shr //sysut2 dd dsn=out1.mmm ,disp=(new,catlg,delete) dcb=( ) // sysin dd * like this what i have to do to skip dsn=main1.sss please giveme answer asap
I have a job called careerride and some steps in it as step1,step2. But I want to execute step2 before step1 ? How do I do that?
My JOB contains three steps. //STEP1 EXEC PGM=ABC //STEP2 EXEC PGM=DEF //STEP3 EXEC PGM=GHI My Question is 1) I want to execute second step only. How will do. 2) Soppose U consider above three steps are in PROC steps and I want execute the PROC second step only? How to execute the second step only. During exection time its creating any ABEND?
