In each run first run of JOB, if the JOB abends the data set will be cataloged and in second run it will give JCP ERROR ( Data set already cataloged). While if in the first run JOB ,it runs successfully data set will be created temporarily to be used by another steps in the same JOB but at the end of the JOB data set will not be there, because it is not cataloged.

RE: DISP Parameter

In such case first time a new folder/file will be created and if succesful completion of programme is there then that program will be passed otherwise the JCL program will be catalogue in this case.

For the 1st time if the job execute successful then data set will be created and then passed to the next step. If the job abbends then it will catalog.
For the 2nd execution it will show that duplicate data set name.

RE: DISP Parameter

Almost correct.

DISP (NEW PASS CATLG)
The results depend on the data set not the run.
If the data set currently exists it would then depend on where it was being allocated. If the allocation was to the same dasd as the current one you would get a jcl error. If it were being allocated to a different dasd your job could run. If the step runs sucessfully the data set disposition would be determined by subsequent steps with the default being delete. If the step abends the data set would be cataloged unless there was a previously cataloged data set by that name in which case it would be kept and you would get a not catlg 2.
