Multi dimensional arrays in COBOL are supported and it is possible to have up to 7 dimensions which is its MAX limit. But more than two dimension array creates confusion.So in general two dimensional arrays and Single dimensional arrays are used mostly. Let us see how to declare and process multi dimensional arrays in COBOL.
At Rimini street, they use micro focus COBOL that are used in Peoplesoft modules. So their main focus would be on COBOL. Knowing people-soft and SQLSERVER is an added advantage. What are the mandatory Divisions? Name different Divisions ? What are the different picture clauses? Difference between Comp and Comp-3 How to declare arrays? What
This SORT example is to add Header and Trailer to the sorted file along with the total number of records. Header –> A Name along with the current System date Trailer–> A static message along with number of input records count Example Sort Card: //JOBRPT09 JOB MSGLEVEL=(1,1),MSGCLASS=X //********************************************************************** //* ADDING HEADER AND TRAILER ALONG WITH
JCL Trick to write the output file in reverse order of input using SORT. If the input file has some records in Random order ( not in sorted order) and if the out file needs to be written exactly in reverse order. This can be achieved by using the SORT Overlay along with OUTREC BUild.
What is a MAP? It is a screen representation of a functionality from where users can access(to perform different functionalities) it. In other words it is nothing but the front end for the mainframe applications. Example -> A Bank Customer Inquiry Screen from where the bank employees/Users access customer details by entering the Customer number
JOBLIB and STEPLIB in JCL both are used to specify the load libraries so that that the programs that are being used in that JCL/JOB are searched in these libraries. Generally z/OS searches for the programs load module in the default system libraries where actually the IBM supplied programs are stored. Specifying JOBLIB/steplib makes the
Sample RUN JCL for a COBOL Program – In Mainframes area any batch COBOL program needs to have its corresponding JCL to run it without which it can not be executed. As we know JCL is a JOb Control Language which is used to run and control the execution of the programs. So JOB written
COBOL Batch program(example) is a cobol program that runs in a bath mode. Unlike the Online programs, batch programs runs in background. To execute any Batch program a JOB written in JCL(Job Control Language) is required. This JOB is also used to specify any files that are used in that program. Generally Batch programs are
Examples of IEFBR14 in JCL: It is an IBM utility used in JCL which does nothing so it is also considered as a DUMMY utility. IEFBR14 does nothing but when running this utility other systems services gets invoked which can perform useful tasks like allocating, creating data sets or deleting data sets etc. So this
This topic covers the JCL Restart parameter with Examples.As the name suggests this is used to Restart a JOB from any particular step instead of starting it from the beginning. This is very useful for the jobs with multiple steps and abends after executing few steps. In this case as few job steps were already
