Hi all,
I need to check whether a particular dataset (given by the user ) is a GDG base,or a seq file or a VSAM file.I have tried with LISTDSI but when I am giving GDG base name then it is showing foll. error::
datset not found with reason code 0005 and return value of 16.
X = LISTDSI(DSNAME DIRECTORY)

If anyone can suggest a solution for this,it might be very helpful.

hi
am not sure how to use LISTDSI, but using LISTDS we can get it.
/*rexx*/
COMPONENT = E0078CE.DEATH.CLAIMS.TRHST
"LISTDS '"COMPONENT"' M"

Output :
E0078CE.DEATH.CLAIMS.TRHST
--LRECL--DSORG-
** VSAM
--VOLUMES-BLKSIZE
**
let me know is there any other way to get it.

I have tried a lot,but not able to get the dataset info'n of a GDG base.It is always saying "Invalid dataset". If anyone has an idea then kindly suggest.
Input is any dataset name and it should tell whether its a GDG base or a VSAM or a sequential file.

expat is right.

If the dataset is a GDG Base, then LISTCAT returns:

GDG BASE ------ entry name
IN-CAT --- catalog name

If the dataset is a QSAM or PDS file, then LISTCAT returns:

NONVSAM ------- entry name
IN-CAT --- catalog name

If the data is VSAM, then LISTCAT returns:

CLUSTER ------- entry name
IN-CAT --- catalog name
