Hi all,

I recently attended an interview and i have some questions which i need some help for the answers.As the questions are from different topics i am addressing them in "application programming" section only.


1.If i have a DCLGEN member called A which i am using in the program by using
EXEC SQL INCLUDE A END-EXEC.Can we write the equivalent of the DELGEN member A in cobol equivalent terms instead of using
EXEC SQL INCLUDE A END-EXEC.If so then what is the difference of using DCLGEN member instead of direct declarations ?

2.When do u decide to use INTERNAL sorting by programatically / EXTERNAL sorting by using DFSORT ? How do we think which one to use and which one is more effficient ?

3.What are the reasons for which SOC7 comes and many programmers come out saying to look out for OFFSET ADDRESS and see the DUMP and trace the statement where SOC7 occured.What is the actual procedure to solve SOC7 in general ? Is there any specific method available?

4.When do we decide to use an INLINE PERFORM / EXTERNAL(NORMAL) PERFORM ? What are the advantages of using an INLINE PERFORM and why do we need to go for it ?

5.How can we know what compiler we are using for our project and which version of Z/OS we are using and what are the types of COBOL available in general which run on Mainframes ? How do we differentiate / know the features of compilers ?

6.What is LE migration and why do we really need to go for it ? If we are not using LE migration what is the disadvantage ?

7.In CICS, if there is a program, a map , a trans id which are all related to a particular task and if we make any changes in the program ,how will the transid make to know about the new load module , is there any command to do that ?

8.What exactly do we mean by packed decimals say comp-3.How is the value stored and dislayed with an example ?

9.How do we calculate the block size BLKSIZE in the DCB parameter in JCL ?

10.How do we know whether we are using JES2 / JES3 subsystem ?
