Hi Friends..

Can anyone help me to clarify doubts in these output msgs..

what is SYSPUNCH used for in jcl , where is it compulsarly used?
and what is the purpose of SYSTSPRT; SYSPRINT; SYSUDUMP; SYSOUT etc ..

SYSOUT = System Output - A DD st that identifies the output data set.

SYSUDUMP - Again a DD st in the job step which directs the system to produce the dump of user areas if the step terminate abnormally.

SYSPRINT - It is provided as file names.But not reserved as file names can be used for other purposes by explicitly declaring it.

SYSPUNCH - A temporary data set to recieve the PUNCH options.

Hope this helps.

Thanks,
KS

SYSPUNCH - in this step you will get output from translator, PASS it to compiler
The temporary data set containing object modules assembled by running the job stream produced by system generation or the GENERATE command. These modules are not installed in the distribution libraries at ACCEPT time.

SYSOUT - The SYSOUT parameter identifies a data set as a "SYStem OUTput" data set, consisting of printed or punched output that will managed by JES2 or JES3. The SYSOUT parameter names the output class to which the printed or punched output belongs and optionally, an external writer, or the forms on which the data set is to be printed or punched, or it can refers to a JES2 /*OUTPUT statement for processing parameters.

SYSIN & SYSPINT - SYSIN and SYSPRINT are automatically provided by the compiler as file names. For this reason, these two files do not have to be declared or explicitly opened. For SYSPRINT, default attributes of STREAM, OUTPUT, and (even though SYSPRINT contains more than 7 characters) EXTERNAL are provided. Unless SYSPRINT is declared or opened as something other than STREAM OUTPUT EXTERNAL, PRINT is also provided as a default attribute. The names SYSIN and SYSPRINT are not reserved by the compiler as file names; They can be explicitly declared and used for other purposes.

SYSABEND, SYSMDUMP, & SYSUDUMP
Use a SYSABEND, SYSMDUMP, or SYSUDUMP DD statement in a job step to direct the system to produce a dump. The system produces the requested dump:
- If the step terminates abnormally.
- If the step starts to terminate abnormally, but system recovery
Procedures enable the step to terminate normally.
SYSABEND
Produces a dump of user and system areas; this dump contains all the areas dumped in a SYSUDUMP, plus:
- The local system queue area (LSQA), including subpools 229, 230, and 249
- The input/output system (IOS) control blocks for the failing task.
The dump is formatted, so that it can be printed directly.
SYSMDUMP
Produces a dump of the system areas and the program's address space. The dump is unformatted and machine-readable; to be used, it must be printed by the interactive problem control system (IPCS).

SYSUDUMP
Produces a dump of user areas. The dump is formatted, so that it can be printed directly.

SYSTSIN
Defines the DSN commands to connect to DB2 Database and to run a program
