How come you can say
| Code: |
//DDN1 DD DISP=SHR,DSN=A.B.C
//DDN2 DD DISP=SHR,DSN=A.B.C |
but you can't say
| Code: |
//DD1 DD DISP=(OLD,PASS,DELETE),DSN=&&ABC
//DD2 DD DISP=(OLD,PASS,DELETE),DSN=&&ABC |
ie, you can reference the same dataset for two DD statements within a step if that dataset is cataloged, but not if it is a temporary dataset? |

| the disp parm OLD, requires exclusive control. You can't have 2 dd statements with exclusive control simultaneously. |

that makes sense I suppose ...and explains why MOD won't work either 
seeing as I can't use SHR with passed datasets, I guess I'll just have to do this in two steps, or catalog the dataset 
...unless there IS a way to use SHR with passed datasets and I just don't know it
thx |

Hello,
What kind of code is running?
Do both DDs need to be opened at the same time?
If the data is processed serially, might one DD statement suffice? |

I was just doing a couple od SPLICEs using SORT
The reason the dataset was repeated was that I'm using Base + Overlay #1 then Base + Overlay #2
I was just saving a step, but I can get around it by using two steps instead. |

Hello,
I believe you could do that with only 1 dd for the base (unless i have misunderstood the process). In your control statements, just refer to the base DD multiple times. Each splice operation should be independent of the other(s). Might it be possible to splice base +Ov1, then base +Ov2. When the smoke clears will there be 1 or 2 output files? If 1, that should do it; if 2, one more splice would wrap it up.
If i've misunderstood, my bad. . . |

you mean instead of using
| Code: |
//IN1 DD <base>
// DD <overlay #1>
//IN2 DD <base>
// DD <overlay #2>
//TOOLIN DD *
SPLICE FROM(IN1) TO(OUT1) ON ...
SPLICE FROM(IN2) TO(OUT2) ON ... |
I could use
| Code: |
//IN1 DD <base>
//IN2 DD <overlay #1>
//IN3 DD <overlay #2>
//TOOLIN DD *
COPY FROM(IN1) TO(TEMP1)
COPY FROM(IN2) TO(TEMP1)
SPLICE FROM(TEMP1) TO(OUT1) ON ...
COPY FROM(IN1) TO(TEMP2)
COPY FROM(IN3) TO(TEMP2)
SPLICE FROM(TEMP2) TO(OUT2) ON ... |
?
It certainly looks like it would work. I'll give it a try. |

It looks to me like files temp1 and temp2 would need to have disp mod.
You could also use "COPY FROM(IN1) TO(TEMP1,TEMP2)" to copy to both files at once. |
