Your answers to questions 1, 2, 6, and 18 are known to be wrong. I haven't looked closely at all the questions to know which other ones are wrong.

Hello,

If these questions (and the other set from your other topic) are the actual questions on the test (as opposed to your presentation of the questions) the tests are somewhat worthless. . . If an organization cannot properly ask COBOL related questions, i'm not sure how they can judge/rate the answers. . .

Here is a link to the Table of Contents for the Enterprise COBOL Language Reference manual:
http://publibz.boulder.ibm.com/cgi-bin/ ... 0/CONTENTS

Suggest you spend whatever time is necessary to research the answers to all of the questions.

If you find something in the documentation that is not clear, post what you found and your doubt. Someone will be able to clarify.
Hope this helps,
d.sch.

People who actually do want to learn are willing to invest in themself. . . The way to learn what you have asked is to do the research (yes, it will take some tme) and post here when you have a question or problem. The post should include what you found and what is not clear about what you found. Someone here will be able to clarify your doubt.

Providing entire laundry lists of answers to interview questions only lets people who are not qualified get better scores on these tests. . .

We are here to explain "things" or help with problems. We are not here to do the work for people or provide them/others with a shortcut to test answers.

We do not have the resources to "teach" but do help people learn.
Hope this helps,

But, as Robert Sample indicates, so many of the answers were wrong that anyone who memorized and regurgitated them in an interview would be most unlikely to get the job, but instead would be dismissed contempuously as an ignoramus.

Hello,

But if we provide all of the correct answers . . .

Who knows, possibly TS has gotten a copy before the interview. . . 8-)

yes,Dick as you said is correct only i understand, but this questions is not as you think,

The institute where i learned the Mainframe,they kept tests to improve our knowledge ,but they didn't given the answers and no body explain the doubts we got in that exams.

no issue on that, but the questions are so badly posed that every answer is debatable...
for example ...
(2) A word in the Computer memory is identified by_________
a) word length
b) word size
c) word address
d) None of the above

only the person who wrote the questions can tell the real <thing> ...
what is the meaning of .... WORD
what is the subtle difference between length and size

if the questions as described here are in the exact wording asked to You
well...
I suggest to change the training institute :D

I tend to believe that the interviewer would expect as answer
the address
the size is defined by the ARCHITECTURE
the length, what the heck does that mean ?
cheers
enrico
When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser,
so that I am sure that the information requested can be reached with a very small effort
