SMRAJAESWARI, now I don't feel quite so bad, as it seems as if the other members of this forum don't know how to answer your questions either.

May I ask, out of curiosity, what type of position within IT these questions are relevant to? They seem like they'd be for a rather high-level senior or possibly even a management/director position?

Hi

Lemme try something !

Did u mean to retrieve previous versions of a program from Endevor? If so, choose the foreground option, give reqd.details abt element; once the element is displayed, type "S" before the element which will display the versions of the program. Choose the version u want to retrieve by typing "R" before that version.

23. How do you specify a list of Loadlibs in a Job

In JOBLIB statement, concatenate the loadlib datasets

Quote:
33 What is Endevor, Have u used it to compile a program

Endevor is Version Control tool. We can compile/bind a program in Endevor using Batch option by specifying where the element needs to be added to.

Corrections welcome !

Thanks & Regards,
kousalya

hi rajah rajaeswari....

this might help u for the 35 questin....

Scheduling simply refers to wen a job must run and in which sequence should a job run.
FORWARD sckedulin means (in jimble words) wat r the jobs that must b run once the job has finisd its xecution.
BACKWARD skedulin means wat al jobs must be run before a job starts its execution.

in a figorical representation,

the forward skeduling of job1 is

job1 ----> job2 ----> job 4
|--------> job3---- > job5

which means at once job1 has run, it triggers job2 and job3 and so on.
Hope u understud raja rajaeswari.

10x,
mft ;-)
