If you use ISRDDN LINKLIST under TSO (ISPF command line TSO ISRDDN LINKLIST), you can see the order of the LINKLIST. This command worked but when I treid to search the member, it showed me this: Œ¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹¹œ 4 *** WARNING *** 4 4 *** WARNING *** 4 4 4 4 T...

The LINKLIST order is established by parameters in SYS1.PARMLIB (different members for static and dynamic link lists).

When I tried to locate that dataset, I got the message that, "No data set names found"! Why would that happen?

Hi,

When we execute a program, how do we know where it was invoked from? I did research around it and got to know that there is a concept of LINKLIST. How to know LINKLIST order when a program is executed? Can some one please help.

You need to move them to edit characters to display them. COMP is of 2 bytes and COMP-3 is 8 bytes. And COMP has sign over punched at it last nibble where as for COMP-3 it will take extra half byte for sign.

Are you fond of cooking?

Thanks all.

Hi, In case if at some point of time DB2 is down, would that impact the pre-compilation process of a DB2-COBOL program? I ask this because when I was compiling a program the compilation went fine but when I tried to execute the job, it went down saying that DB2 is down. Later I came to know that, DB...

Yes, both are invoked by the EXEC statement, but different formats of the EXEC statement, which do different things. A PROC contains JCL. A PGM is executable. PROCLIB tells the system where to look for (additional) PROCs. STEPLIB tells the system where to look for (additional) PGMs (executable prog...

What is the difference between steplib and proclib? When in a JCL, both programs and procedures are invoked by way of EXEC statements?

Thanks Robert.

Thanks Robert.

Thanks Robert - this is helpful.

Thanks Robert.

Thank you Robert.

Thanks Robert. Experience speaks...

As far as I know - in old days, STOP RUN was the only way to "stop" the program - does that mean, during those days CICS had frequent problems because of STOP RUN?

If it is so - then what are the practical uses of GDGs? Why can't we just use a simple sequential file?

Thanks Robert. I did miss that.

It solved the problem.
