| If you are referring to the EDIT function of ISPF, CSA has nothing to do with your S878. The REGION size of your TSO session is not large enough for what you want to do. |

The manual says the reasons for an S878-10 are:
| Quote: |
10
There is not enough virtual private area storage available to satisfy the request. This is due to one of the following:
* A program is requesting virtual storage, but not subsequently freeing the storage.
* The region size specified is too small.
* An installation exit is requesting virtual storage from a V=R region before initialization of the region has completed. |
Exactly which of these reasons is it indicates to you that CSA needs to be increased? I certainly don't see any mention of CSA in any of the manual explanation.
Terminology note: CSA refers to a specific type of memory on a z/OS mainframe and cannot be used as a generic term for memory. And CSA is not the memory causing your S878-10 abend.
Contact your site support group to find out how big to set the region size on your TSO session, log off TSO, and log back on with the increased region size your site support group recommends. |

Terry Heinze,
Thanks for showing some guide lines in order to help me out..
But I can submit jobs (with the same TSO ID) which can create output files which is much larger than the data set which I am trying to modify now

Thanks for showing interest to solve the problem..
But one of our expert forum members had over come the same problem (but through job) by increasing CSA size, the same information I have observed in our forum page only
Unfortunately  there is no information available on how to increase CSA size

Personally, I'm impressed that you have decided that TWO senior members here are wrong in what they're telling you and you know the correct answer. That takes a great deal of confidence in your own abilities and the willingness to ignore common sense.
CSA is easily changed. Contact your site support group, have them adjust the CSA value in the SYS1.PARMLIB member IEASYS00 (or whatever it is named at your site), and IPL your LPAR. That will adjust the CSA to the new value. It is not possible to adjust CSA without an IPL, although large LPA stacks can reduce the CSA available if LPA needs more memory.
However, do not be surprised if you continue to get S878-10 abends when attempting to edit the data set since CSA size is not your issue. And your comment to Terry about batch jobs creating much larger files that what you are trying to edit is totally irrelevant -- if you don't try to edit the file under TSO, the situation is not the same. |

And there is no reason to do this. . .
Not every sequential dataset should/can be edited. . . Editing is for small datasets. If changes are needed in large datasets, some other method should be used. |

| Your TSO region size (for ISPF edit purposes) is not necessarily the same, and usually isn't, as the REGION size of your batch jobs. |

are You aware that ISPF edit will load in memory all the records of the dataset being edited ?? |
