How many bytes occupied following comp example?
This is regarding COBOL comp.
PIC X(3) occupy the 3 bytes... but PIC 9(3)V9(7) COMP occupied how much bytes?
I said in interview that 10/2 = 5 bytes. V is specified for decimal point.
Is that correct? But interviewer looked at me differently when I said this answer?
If you are more confident, please reply this ...thanks...
What is the difference between NEXT SENTENCE and CONTINUE?
NEXT SENTENCE gives control to the verb following the next period. CONTINUE gives control to the next verb after the explicit scope terminator. (This is not one of COBOL II's finer implementations). It's safest to use CONTINUE rather than NEXT SENTENCE in COBOL II.
Concatinating two rec by using COBOL & JCL
I need to concatenate records by using cobol and jcl (both) as follows.
Split the file into two halves and
1st rec of first half and 2nd rec of second half records are concatinated and
2nd rec of first half and 2nd rec of second half records are...
What is the difference between static & dynamic call?
In the case of static call the mainprogram and subpgms r loaded into the mainmemory initially.in the case of dynamic call only the mainpgm is loaded first and the subpgm is loaded only when a call to it is made.so the memory utilization is good in dynamic call.
Dynamic Linking in COBOL
I have two modules called 'A' and 'B'. Module 'A' opens the ORACLE database connection, and Calls 'B', which queries the database using the 'SELECT' statement.When I hard code the module name during CALL, the called module uses the database connection opened in the module 'A'. Pls refer below:CALL "B"But, when I moved the module name into a variable and try to call the module, as belowMOVE "B" TO...
Explain the difference between an internal and an external sort, the pros and cons, internal sort syntax etc?
An external sort is not COBOL; it is performed through JCL and PGM=SORT. It is understandable without any code reference. An internal sort can use two different syntaxes: 1.) USING, GIVING sorts are comparable to external sorts with no extra file processing; 2) INPUT PROCEDURE, OUTPUT PROCEDURE sorts allow for data manipulation before and/or after the sort.
