Time, Priority parameters in jcl

Time parameter in jcl:
 
   Time is key word parameter in jcl. time parameter is used to specify the time
    required to exhigute the job.
 
     Mainframe interview questions and answers, jcl interview questions and answers for 
   what is Time  parameter in jcl, how  Time parameter give in job card in jcl 

   The jcl job cart contain two types of parameters one are positional parameter and 
     another are key word parameter. in these positional parameters are mandatory and
    key word parameters are optional.

   The Time parameter is used to exhigute job with in a specified time.
    the time parameter can be specify at job level and also at step level.
    if we specify time parameter at job level The given time can be shared
    to all the steps in job. if we specify time parameter then that only to
    that step only does not share to other steps.
   
    the time abends which occur are
    S322--->if given time specify in time parameter is not sufficient for that job.
   
    S522--->If job exceeds the waiting time.
 
    To avoid this we can give default time parameter as '1440'

    give the priority to jobs to exhigute in MVS. we can give 1-15 in priority
