1)How to Read comp3 data?

YOU CAN ACCEPT AND DISPLAY THE COMP-3 VARIABLES


2)Can i rewrite a sequential file in tape? if yes how?

YES. YOU CAN REWRITE. THE FILE YOU ARE TALKING ABOUT IS THE ESDS FILE.
OPEN THE FILE IN I-O MODE.
AND ACCESS MODE RANDOM OR SEQUENCIAL.
READ THE FILE FIRST , DEPENDING ON THE FIELD.
SEARCH THE FIELD WHICH YOU WANT TO REWRITE AND
THEN REWRITE IT.


3)How many procedures can i write in ajob?

YOU CAN UPTO 15 PROCEDURES IN ONE JOB .


4)What is Vsam Reorganization? and how frequently we need to do that?

REORGANISATION, THE TERM ITSELF INDICATES THE MEANING.
WHEN WE ARE USING THE VSAM DATASET AND IT SEEMS THAT IT DOESN'T PERFORM SOME OPERATION
BECAUSE OF WHAT WE DEFIEND WHILE CREATION. SO WE HAVE TO GO FOR REORGANISATION.
YOU NEED TO CHECK THE COMPILER OPTIONS. SOME COPLILER DONT ALLOW TO CHANGE , WHAT YOU HAVE CODED.



6)how did u choose control area size in ur application?

PAY ATTENTION. WE ARE DEFINING ANY CONTROL AREA SIZE IN THE CREATION.
WE ARE ONLY CODING THE CISZ OPTION. THAT IS CONTROL INTERVAL SISE.
CONTROL AREA SIZE IS DECIDED BY THE ADMINISTRATOR,NOT BY THE PROGRAMER.



9)what is difference between qmf and spufi?which one is best?

BOTH HAS ITS OWN IMPORTANCE.
QMF IS QUERY MANAGMENT FACILITY AND
SPUFI IS SQL PROCESSING USING FILE INPUT.
IN SPUFI WHATEVER QUERIES YOU ARE CODING WILL BE AVAILABLE IF YOU LOGOFF AND LOGON AGAIN,
BUT IN QMF , ONCE YOU ARE OUT OF QMF REGION THE QUERY IS GONE.

IN BOTH CASES WHAT EVER OPERATION YOU DID WILL BE REFLECTING IN THE TABLES.
