I need to copy all the generations of GDG(LRECL=1500) to new GDG with increased LRECL of 2500.
I am using below Sort card and it works fine
| Code: |
//SYSIN DD *
SORT FIELDS=COPY COPY SORT COMMAND
OUTREC FIELDS=(1:1,1500, REFORMAT OUTPUT RECORD ADDING
1501:1000X) 1000 BYTES OF SPACES
/* |
But to repeat the same process everytime for all the generations is a tidious job.
I need to automate it.
1. Did a listcat for the desired nodes and formated the listcat output with ezt. Now I have a dataset with all the gdg generations which needs to be changed.
2. Created base with new DSN and now just need to copy all the generations from old dsn to the new DSN.
Cud you plz help if I can automate it to read gdg gene
Input - XXXX.ABC207M.IDCAMS.XX.AK.YE
Desired output (with all the generation copied and increased LRECL)-XXXX.ABC156G.IDCAMS.XX.AK.YE
Code'd |

| Write a little bit of Rexx or COBOL to read the input data set and fabricate JCL and *sort control cards; either use the TSO SUBMIT command (in Rexx) or write the JCL to the internal reader (in COBOL) to execute the job. |

Do you mean: "Could you please..."?
Plenty of examples on the forum - have you searched? Or asked your colleagues? Or your local Rexx Guru? |

Basically I am a beginner in RExx,Just got the basic idea abt rexx from manuals.
In my Input dataset I have the list of all gdg generations to be converted into 2500 LrecL with a new name or i can have same name and just inrement version num.
I am stuck at a point how the file name will be sent to JCL. The JCL shud be called for every file from the REXX routine in a loop.
Even if i am able to pass gdg for sort in, how do i interpret the sortout gdg generation as the desired output is like this.
Input - XXXX.ABC207M.IDCAMS.XX.AK.YE.g***
Desired output (with increased LRECL)-XXXX.ABC156G.IDCAMS.XX.AK.YE .g***
2nd option is to use just version number 01 instead of 00 for the generations and in this case i can keep the same dsn name XXXX.ABC207M.IDCAMS.XX.AK.YE.g***v01 |

You can dynamically allocate and process each of the input and output files in a loop within the batch job that you submit.
Do not use the version number solution because only ONE version of a given generation can exist, so if your copy fails you may well delete the input data for that generation. |

Read all generations in one go like this...
//INPUT DD DSN=input.gdg.base.name,DISP=SHR
//OUTPUT DD DSN=output.gdg.base.name(+1),DISP=(,CATLG)...
to create one new output generation on your new GDG |

| I think she wants one output generation per input generation. However, that's a trivial enough thing that the hints she's been given so far should be more than adequate. |
