How do I remove duplicates from a mainframe file?

Probably you want to say, "I would like to keep the order of the input records when they are copied to the output file"... if so, eliminating duplicates, either by using SUM FIELDS=NONE or SELECT, requires sorting the records so that the records with the same key are in order.

How do I remove duplicates in VSAM?

What is the difference between Inrec and Outrec in sort?

How do you call a proc in JCL?

It should start with a PROC statement and end with a PEND statement. In the above example, the procedure INSTPROC is called in STEP1 and STEP2 using different input files. The parameters DSNAME and DATAC can be coded with different values while calling the procedure and these are called as symbolic parameters.

Can you code instream data in procedure?

You cannot use instream data inside a PROC. It is a rule. Instead, you code some dummy statement inside the PROC and override the particular step's DD statement from the JCL before you execute it.Bah AP

What is instream data?

An in-stream data set is a data set contained within a set of JCL statements. In-stream data sets (also called inline data sets) begin with a DD * or DD DATA statement. These DD statements can have any valid ddname, including SYSIN .

How do you skip a step in JCL?

A COND parameter can be coded in the JOB or EXEC statement of JCL. It is a test on the return code of the preceding job steps. If the test is evaluated to be true, the current job step execution is bypassed. Bypassing is just omission of the job step and not an abnormal termination. AP

How do I run a specific step in JCL?

How do you restart a job in JCL?


  1. Syntax: RESTART = [stepname.] ...
  2. Example 1: //MTHEXMP1 JOB (META007),'PAWAN Y', RESTART=* //STEP01 EXEC PROG=A . . ...
  3. Example 2: //MTHEXMP2 JOB (META007),'PAWAN Y', RESTART=STEP02 //STEP01 EXEC PROG=A . . ...
  4. Example 3: //MTHEXMP3 JOB (META007),'PAWAN Y', RESTART=STEP02.PROCB //STEP01 EXEC PROG=A . . ...
  5. Example 4:

How do I restart a specific step in proc?

JCL RESTART is an optional keyword parameter which is used to restart a job from a particular step. Suppose, you have a JCL which has 3 steps(STEP1, STEP2, and STEP3) and you want to run the JCL directly from STEP3, then you can directly code the RESTART parameter at STEP3.

What is time parameter JCL?

TIME parameter specifies the maximum amount of time that step may use the processor. In other words, TIME specifies the maximum CPU usage time allowed for the step to execute. TIME parameter is optional parameter.

What is Parm JCL?

JCL EXEC PARM The PARM parameter is used to pass the input data from job step to program. ... If JCL needs to pass more than one sub parameter, those should be separated by comma (,) which are enclosed in parentheses/quotes. PARM parameter can pass maximum 100 characters.

How pass value from one program to another in Cobol?

Call Verb. Call verb is used to transfer the control from one program to another program. The program that contains the CALL verb is the Calling Program and the program being called is known as the Called Program. Calling program execution will halt until the called program finishes the execution.

How is GDG defined in JCL?

Create/ Alter GDG in a JCL

  1. NAME specifies the physical dataset name of the GDG base.
  2. LIMIT specifies the maximum number of versions that the GDG base can hold.
  3. EMPTY uncataloges all the generations when the LIMIT is reached.
  4. NOEMPTY uncataloges the least recent generation.

What are the various ways of passing data from JCL to program and how do you receive them in program?

The two techniques use to pass information (a Parameter) from JCL to a program are as follows. This technique uses a PARM=parameter keyword on the EXEC statement in JCL. The COBOL program requires a LINKAGE SECTION. This technique requires a SYSIN statement followed by the parameter to be placed in the JCL.

Which parameter provides the storage specification of a job step?

The Data Control Block (DCB) parameter details the physical characteristics of a dataset. This parameter is required for datasets that are newly created in the job step. LRECL is the length of each record held within the dataset.

Which are the two system utilities that allow you to maintain and manage catalogs?

The IEHPROGM utility is used primarily to manage catalogs, rename data sets, and delete data sets. Most of the IEHPROGM functions are available through access method services (the IDCAMS utility), which is now the preferred utility for catalog and data set functions.

What is DD dummy in JCL?

//SYSIN DD DUMMY. DD - Connects program input/output to data. Input can come from a file (dataset) or instream data (part of the JCL stream) Output can go to a file (dataset) or print queue (Usually sent to some kind of printer or HOLD queue) SAMPLE INPUT DD STATEMENTS: When Input is a catalogued file.

What does Sysout =* mean?

SYSOUT=* denotes that the output will be displayed in the class which is defined in the MSGCLASS. If you do not define MSGCLASS, the system will by default define a particular Class.
