Hi,

What does PSB(n) signify in the following command?

EXEC DLI GU USING PSB(n) where 'n' is any numeric .

Regards,
Rony Susan

RonyS,

PSB stands for Program Specification Block which consists of one or more control blocks called Program Communication Blocks (PCBs). The PSB contains one PCB for each DL/I database the application program will access.

Check this link which explains it in detail

Thanks Kolusu for the reply.
I was looking for what does it means when we give a numeric value for PSB, as I couldn't get a clear understanding. Is it the number of the PCB within a PSB , hows it related...

Thanks

Which language are you using as that does not look like COBOL, PL/1 or assembler?
