Dear All,
I do see the output file defined with dummy followed DISP=SHR,DCB parameters. Is there any use DUMMY with parameters DISP and DCB?
Can you please tell me what will happen if we don't use those parameters.
| Code: |
//OUTPUT1 DD DUMMY,DISP=SHR,
DCB=(RECFM=VB,LRECL=2004,BLKSIZE=2008) |

Have you tried the JCL manual?
Doesn't hurt to try, does it?
Often you'll see stuff lying around after overriding a DD to DUMMY.
Someone once joked that with huge blocksize/buffers the data would get igrnored quicker. Try it. Maybe it wasn't a joke... |

it is so easy to test, why don't you try?
at my site, the set-up is such, that any dummy, requires some dcb parms. |
