Hi all
I am getting invalid dataset name while processing the input file verifying the file with SYSDSN when the input gdg file is given with version (0)?
Thanks

Correct, you would do, if my assumption is correct, but as there is insufficient information to verify that .......... 
Either define the relative generation as zero in the JCL if you are running in batch mode, or - and there are some examples on doing this on the forum because both Enrico and I have posted different options to get the absolute generation of the latest GDS within the REXX code and then allocate it using said absolute generation.

N.B. I am sure that you really meant GENERATION rather than version didn't you, after all both are equally valid and have completely different usage, not to mention that you WOULD NOT code the version number as (0).
I won't go into the file / dataset thing again either 
AND AGAIN Do try to give us at least the bare minimum information - because you have posted in the REXX section I can only assume that you have a problem with some REXX code. A snippet of code would help. Anything really !!!
Please try to help those willing to help you !!! |

As expat says, in this context (0) is a generation. It is not a version. Learn to use correct terminology. In a generation data group there are versions within a generation, but these are different and extremely difficult to use.
In sysdsn(xxx(0)), xxx is considered to be a partitioned data set. xxx(0) is invalid because 0 is not a valid member name.
If your Rexx EXEC wants to use relative generations, if must determine, very manually, the GnnnnVnn of generation 0 (or whatever generation you're interested in) and then use sysdsn(xxx.GnnnnVnn). |

Thanks expat. I get the Dataset using the below piece of code
| Code: |
/******REXX****/
Say 'Enter the DSN:'
pull dsn1
z=SYSDSN("'dsn1'")
if z='OK' then
do
say 'valid dsn'
else
say 'invalid dsn'
end
exit
|
When i give gdg with generation i am getting invalid dsn. |

As I said yesterday, there is code on the forum that will give you what you exactly what you want.
If you know the GDG base then you can easily find the zero generation - I searched and found it on this very forum.
So a helpful hint - you need to translate the relative generation into the absolute generation.
Exactly the same response as my first post above.
and Steve-Myers has told you the reason that it is failing.
And yet again, you give absolutely minimal information in your post. Whooppee Dooppee Sooooooooo for the information that you get the dataset name from your REXX and still you get errors.

So would that be using a relative or absolute generation, or was there no generation specified by the entrant, who gave only the base.
Unless you start giving some useful information you will find that the topic is locked. And the amount of information that you do give, I think that some posters on the beginners forum post more meaningful information than you do.
Unless you can give a detailed and information loaded explanation of what you are trying to do, how information is entered into this code and absolutely anything that may be helpful I may as well close the thread to save the further waste of anyones time. |

for starters, this code is plain wrong:
you need to add two more double-quotes like so
| Code: |
| z=SYSDSN("'"dsn1"'") |
otherwise it doesnt matter whatever else you do. |

| Have you turned on tracing? If not, why not. If you have then post the output from the trace. |

after 13 ( THIRTEEN) years of hanging around
You should know that TSO commands DO NOT deal with GDGs
they deal only with REAL ( as they are stored in the catalog and the VTOC ) dataset names
it has been suggested for gaziliions of times that to find the real name of a GDG generation
the proper way is to use the IBM provided BPXWDYN

Nope ...
it' s tragedy season
on another forum a Senior suggested that a program was failing
because of a missing end of file marker 
but when they deleted the last record the program was ok
sometimes I wonder |

| In ISPF 3.4, if gdg with (0) is given then the whole gdg is shown. can i use edit macros to get the gdg with generation? |

Yes, but you would have to be editing a dataset - it is an edit macro after all - and the macro would be about the same as a Rexx program.
Why not just provide us with the information requested including the trace and we can analyse your problem properly? I have an idea as to what is wrong as, I am sure, do others but without the information we are only guessing. |

Ye gods, and for how many more times must I repeat myself ....
There is code on this forum that will give you the absolute generation from a relative generation.
I found it easily ................ so can YOU !!!!
a clue, search for both keywords, absolute AND relative
