Hi all,
I have a PDS where I have all my cobol programs. When I checked this morning, its all formatted differently. I can't even open in Edit mode. even if I say open with Edit....it still opens with Browse mode.
-------------------------------------------------------------------------------------
Name Prompt Alias-of Size TTR AC AM RM
_________ JRP007 *Viewed 00296F17 008608 24 24
_________ JRP007S 00250F16 006B06 24 24
_________ JRP032 00213F10 004908 24 24
------------------------------------------------------------------------------------
I can't even see my user ID on the screen to the right....its showing all this Alias-of, size which I have never seen before.
can anybody tell me what might have caused this change to my PDS and how to rectify it????
Thanks,
RC

| Since you stated that the library is supposed to contain COBOL source code, did you or someone else attempt to use that PDS as the target ouput loadlib dataset for a COBOL compile process? |

Most certainly Your pds containing source code was the target of a linkage editor and the recfm was changed to U
if You remember the original dcb attributes
RECFM=FB;LRECL=80,BLKSIZE=original_blksize
take a backup of Your corrupted dataset
then You can try to fix the dcb attributes by running a job like:
| Code: |
//IEB EXEC PGM=IEBGENER,
//SYSPRINT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT1 DD *
DUMMY LINE
//SYSUT2 DD DISP=SHR,DSN=your_dataset_name(DUMMYMBR),
// RECFM=FB,LRECL=80,BLKSIZE=the_original_blksize
|
otherwise restore from the most recent copy |

YES!!! I used it last week for an unrelated testing of another program. I compiled that program and gave the target as that PDS which is having the problem. Wow!! So, that why it has messed up my other programs in that PDS???!!!
How do I rectify it??? do I just delete the object module that used this PDS??
Please let me know?
Thanks,
RC |

Hello RC,
Have you done what Enrico suggested? That has worked for others who have done the same thing.
Is there some reason that you "made up" some compile jcl for your program? Every developer should use standard compile/link jcl for all of their work. Custom jcl should not be used.
Two main reasons to use standard jcl are:
1. When some option is to be changed, it only needs to be changed in the standard jcl.
2. To prevent things like this from happening. |

You are absolutely correct. The recfm for that PDS has changed from FB to U.
Please let me know how you restore?
Thanks,
RC |

Hello,
Your quote contains the step you need to run. . . The IEB step. |

Hello Dick Scherrer,
The reason why I had to use my own PDS is becuase that prgram was a sub-routine pgm, used by many other programs and it would not allow us to compile/link in the standard PDS for the object modules. So, i just gave my PDS.
I did not understand the JCL that Erico gave to restore. there are about 30 to 35 programs in that PDS...do I run the jcl for each program one at a time, for each program?
Thanks,
RC |

Hi RC,
the step I gave You will not restore anything,
it will only fix the dcb of the pds so that You might be able to recover some sources...
Ffrom the description of Your actions I am afraid You will not recover too much...
usually the output member has the same name of the source member ...
so You might have overlaid a source with a load. |

Hello,
First, backup the pds as it is right now.
Second, modify the jcl Enrico posted for your dataset name and use the DUMMYMBR he mentioned ( you are not going to actually do anything to the other members in the pds - your job will reset the dcb attributes and all of your source (except may be the one that got linked over) should be "restored". It is not really a restore, but a reset of the definition of the pds.
Again - first back up what you have now. Hopefully not, but it may be needed.
Good luck, and someone will be here if there are questions. |

Thanks a lot!! I have fixed the problem by running the jcl which Enrico posted.
Thanks to both of you.
