These Questions have been asked in Cognizant(CTS) for Mainframes Technical round of Interview. CICS & VSAM–> What is the MAX size of COMMAREA? What happens if we try to send the data with size more than 32k? While passing data between two programs(PGMA TO PGMB) using COMMAREA. If in PGMA The commarea size is 30
Scrollable cursors are introduced to overcome the limitation of reading the result table in sequential order.In Normal cursors, the cursor places at the first row of the result set when OPEN cursor statement is executed.

Header –> A Name along with the current System date Trailer–> A static message along with number of input records count Example Sort Card: //JOBRPT09 JOB MSGLEVEL=(1,1),MSGCLASS=X //********************************************************************** //* ADDING HEADER AND TRAILER ALONG WITH
JCL Trick to write the output file in reverse order of input using SORT. If the input file has some records in Random order ( not in sorted order) and if the out file needs to be written exactly in reverse order. This can be achieved by using the SORT Overlay along with OUTREC BUild.
