Reply with quote

Hi all,

I am using a CLIST to write into a PDS. But before writing any records to the PDS, the program should check if the user has the authorization to acces the PDS. i.e to check for access to some High Level Qualifiers.

Is there any command that can help me out here?

A similar CLIST is shown below.

Code:


PROC 0                                                           
ALLOCATE FILE(RTSTR) DA('NUP.RT.SRCH.Q') MOD REU   
OPENFILE RTSTR OUTPUT                                           
SET RTSTR = &SYSNSUB(1,ABCDEFG)                                   
PUTFILE RTSTR                                                   
CLOSFILE RTSTR                                                 
EXIT CODE(0)                                                     



The o/p im getting currently is:
Code:

OPENFILE RTSTR OUTPUT             
INTERNAL COMMAND PROCEDURE ERROR+   
EXEC ERROR CODE S913               


Could you please help me here?

Do the same commands(mentioned in the thread provided) work for CLIST as well? I guess not.

I just did.
It then tells to include /* REX */ as the first command.
Without /* REX */ it does not recognize the commands.....

the link was not about the code, but about the logic,
if You are not authorized You will get an error,

the best thing would be to run three tests
1) dataset exists
2) datasets does not exist
3) dataset exist but You are not authorized to it

watch the return code decode it and act accordingly!

I have tried couple of commands in CLIST including LISTDSI, SYSDSN...
These do tell about the dataset availability...but cannot tell if i have authority to access a PDS or not.

There is a High Level Qualifier for which i can access the PDS characteristics but donot have read or write access. Im getting RC0 for above listed commands, hence unable to handle the error...

I am very new to CLIST and have not coded in REXX too...can u please tell if there is a way to execute REXX commands in CLIST?

The commands are TSO commands and therefor common to both REXX and CLIST.

You'll need to invoke the API for the security package used on site -- RACF, TOP SECRET, ACF2 -- and pass it the appropriate data to get back the access authorization. You'll probably want to get with your site security team to determine the best way to achieve your goal.
