Hi all,
How to check in rexx for file attributes,especially block count!!
My requirement is to find out whether the file is empty or not before opening it in browse mode.LISTDS is not giving block count.
If somehow I can getthe block count in the current utilization part as in the attachement, with that I can decide whether the file is empty or not.
Thanks in advance,
Ceema Rajith |

Ok now from the start.

I am not sure it did, and I am not sure what you exactly mean by "block count".

You cannot ask to LISTDSI to not generate message and as well to ask to receive information from it !!!
So give us the kind of message you want to avoid.
Also, do you run this in background or in foreground ?
Finally do you just want to know if a file is empty or not? If so, LISTDSI is not convenient.
Use IDCAMS, or EXECIO and test the return code, ...
Please clarify
Cheers

Perhaps, just maybe if you follow the instructions below
Post your code, and the messages that you wish to dispose of
then we might actually be able to help you. |

My code is
FATTR = LISTDSI("'"DSN"'")
IF FATTR == 0 THEN
IF SYSUSED == 0 THEN
SAY "EMPTY FILE"
ELSE
DSNCAT = 'YES'
Here I'm checking for a empty datset..so in the screen i'm expecting only 'EMPTY FILE' but what is comming
"IKJ56712I INVALID KEYWORD, "AX.IOLDI.G.DATA.AUSTRIA.G0146V00"
EMPTY FILE
Please guide me to avoid the first line from the screen |

DSN is AX.IOLDI.G.DATA.AUSTRIA.G0146V00 , it filled properly.
My problem is the message "IKJ56712I INVALID KEYWORD, "AX.IOLDI.G.DATA.AUSTRIA.G0146V00"
which is generated by LISTDSI.I want the customized display only |

Yes, but something is running wrong. Try the trace option : it will show you all info.
Because you cannot avoid message IKJ type.
You did not respons to that : batch or online?
