True to the name, interviews are meant to be interactive sessions where the exchange of information is not limited to linear or one dimensional flow of data. Keeping that in mind, it is important to keep in mind that potential candidates like you need to focus as much on the communicative part as on the theoretical knowledge of the subject concerned. So far as the latter is concerned, it is essential to check your basics and hold your foundations right.<\/span><\/p>\n\n\n\n

Here are some of the most frequently asked JCL interview questions and answers to help you ace your next interview.<\/strong><\/span><\/h2>\n\n\n\n

1. What do you understand by the term JCL?<\/strong> <\/span><\/h3>\n\n\n\n

Job Control Language is basically the foundational provider of several program resources and an essential arbiter between the operating system and the program. Also, it is important to keep in mind that JCL is not a procedural language. At the same time, it is apparently impossible to run a program on mainframe without the applicability of JCL. <\/span><\/p>\n\n\n\n

2. What do you think is the meaning of the symbol \\?<\/strong> <\/span><\/h3>\n\n\n\n

This is especially important in that any JCL statement must begin with this symbol. Indeed, the absence of the same leads to the indication of an error since the symbol is the first thing checked in JCL. It is the default rule in JCL which is used in order to keep runtime exceptions at bay. <\/span><\/p>\n\n\n\n

3. Do you think that automatic restart is feasible in JCL?<\/strong> <\/span><\/h3>\n\n\n\n

Yes, it is possible to have an automatic restart in JCL through the help of a predefined keyword parameter. Specifically, the RD keyword is the one used for the purpose of restart which generally succeeds an anomalous termination of the program. Against the backdrop of automatic restart, you need to consider the significance of check points which are used to define the job execution at various points in the program concerned. <\/span><\/p>\n\n\n\n

4. What about condition checking in JCL? Is that possible?<\/strong> <\/span><\/h3>\n\n\n\n

So far as condition checking in JCL is concerned, it is indeed possible. Moreover, condition checking is feasible at both job level and the code level. Technically speaking, condition checking is done through the COND keyword with a return code and operand as predefined in JCL. So it is viable. <\/span><\/p>\n\n\n\n

5. Can you tell us something about the crucial error execution phase?<\/strong> <\/span><\/h3>\n\n\n\n

The error is chiefly induced due to anomalous exceptions encountered in the course of the program. So far as the error execution phase is concerned, JCL consists of eight cardinal error codes for the execution phase. For instance, misplaced statements and the absence of apostrophes lead to the validation of error checking in a JCL program.<\/span><\/p>\n\n\n\n
