What do you mean exactly by "extracting"?
Is it copy the file or running a program on that file to apply some process on the records ( selections, ..)? |

So why do you need to extract the generation number every day. What purpose does it serve ?
There is a thread that will allow you, with a little code change, to do this in REXX
Click HERE
Also consider writing your own code to use in 3.4 - some good examples, hints & tips in the forum already. |

I am sure that you really meant to say gdg generation rather than version. Version has a completely different meaning to generation.
I know what extracting meant, just curious as to the reason why this needs to be done ? the latest generation can always ve addressed via gdg.base(0) |

I got it....
but I have 25 gdg bases....so in ISPF 3.4 i have to enter 25 times to get latest gdg version of each gdg base....
I wanted to do this at a time ...so that it lists me latest gdg versions name of all 25 gdg bases |

Hello,
How will knowing the latest generation meet any requirement other than curiosity? Any job that needs to use the latest data can simply use dsn(0).
There must be something i misunderstand  |

I understood gdg.base(0) version points to latest version...
but that is not my question......
I want to list out the name of latest version each 25 gdg.base has . how do you do it.......instead of going to ispf 3.4 25 times.
Please let me know, if you need any other information.
Thanks,
Praveen |

Why do you have to use ISPF 3.4?
Expat has provided REXX code that with some tweaking will do what you want. You could also use LISTCAT in a batch job to list the generations for each GDG base and a little programming will extract the latest generation from the LISTCAT output.
Either way would solve your 'problem' but not use ISPF 3.4 yet you don't seem to want to use Expat's solution -- so the key question has become, why do you have to use ISPF 3.4? |

Hello,
We understand what you want to do. . . We do not understand why you want to do it
If you explain why you want to do this (rather than just avoiding 25 trips thru 3.4), we may be able to offer better suggestions.
As i asked before, what sort of requirement will this fill? Once gathered, how would the data be used? |

useful technique because tso alloc, listdsi, etc don't handle GDG relative generation names.
| Code: |
/* REXX */
/* FOR Z/OS 1.8 OR LATER */
/* ftp://ftp.software.ibm.com/s390/zos/tools/bpxwdyn/bpxwdyn.html */
call bpxwdyn 'ALLOC FI(A) REUSE DA(MBABU.GDGS(0)) SHR RTDSN(GEN)'
say gen |

Hi,
I extracting latest gdg just for documentaion purpose....and gdg base is defined in such a way that generation will be on disk for long time...so i am extracting latest gdg generation and copying them into personal file.
Thanks all....
for extracting latest gdg version for 25 gdg base i used the rexx
| Code: |
*******REXX**********/
SAY 'THIS IS EXISTING INBOUND FILE'
SAY 'BLUCHIP GENERATION********************'
"LISTCAT LVL(PECS.BLCHIP.IFF.BN.DATA)"
SAY 'AK STEEL/ARMCO***********************'
"LISTCAT LVL(PECS.ARMCO.IFF.BN.DATA)"
SAY 'ALCOA*******************************'
"LISTCAT LVL(PECS.ALCOA.RETHMO.IFF.BN.DATA)" |
I ran above rex by batch program.....
| Code: |
//LIDUOCUA JOB (500,CC4976),'JCL4REXX',
// REGION=0K,
// CLASS=B,
// MSGCLASS=2,
// NOTIFY=&SYSUID
//TSOBATCH EXEC PGM=IKJEFT1A,DYNAMNBR=200
//SYSEXEC DD DSN=PBCL.TMEMBER.REXX,DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTSIN DD *
PROFILE PREFIX(LIDU0CU)/* PLEASE USE THIS,*/
%REXX
/* SPECIFYING YOUR USERID*/ |
....it gave me what i want....
now...i need not to go every time 3.4 to get latest gdg version
thanks all once again,
Praveen |

If you just want to get the latest gdg generation with a batch job you can pretty well use the job below...
| Code: |
//STEP10 EXEC PGM=IDCAMS
//DD1 DD DSN=YOUR.GDG.BASE1(+0),DISP=SHR
//DD2 DD DSN=YOUR.GDG.BASE2(+0),DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
PRINT INFILE(DD1) COUNT(0) CHAR
PRINT INFILE(DD2) COUNT(0) CHAR

Is this what you are expecting or did i overlooked at something
