A)    It enables one to save memory space
B)    It helps to reduce coding effort
C)    It can be used only with the move verb
D)    It  helps to create more efficient object code

 

  • Which one of the following is false?

A)    If there is no parenthesis in a compute, then a division is always done before a subtraction.
B)    All the four arithmetic operators namely, +, -, * and / can be used in the same compute statement, if required

A)    It is used for individual data items in working-storage section
B)    It is used for items with renames clause

B)    The SEARCH verb can only be applied to a table which is defined with the occurs clauses and indexed phrase
C)    Every search statement must contain the AT END clause
D)    The SEARCH verb passes control to the next sentence when either a when condition is satisfied or the end of the table is reached without satisfying any of the when conditions

 

  • Which of the following is false?.

A)    It is possible to write programs without using GO TO
B)    The target of a go to statement being a procedure name, avoiding go to results in a program with no procedure names.
C)    Indiscriminate use of GO TO is not advisable as it can make the control structure of a program substantially complex
D)    Excessive use GO TO statement can make programs difficult for others to understand

 

  • Which of the following cannot help us to get the reduce memory requirement of a program in COBOL?

A)    Reserve clause
B)    Redefines clause
C)    Same record area clause
D)    Rerun clause

  • Which of the following is true about the RESERVE clause?


A)    This is a part of file descriptor entry for a given file
B)    This is used only for file with block contains clause
C)    This is used whenever more than one file is processed in a program
D)    This can be used to save memory space by specifying one buffer instead of the usual two buffers

Note:-
RESERVE clause
The RESERVE clause allows the programmer to specify the number of record buffers to be allocated at run-time for the files.
Example RESERVE 2 AREAS
mean that two record buffers are to be allocated.

B)    The case structure can be implemented through nested if sentence
C)    The case structure can be implemented through a sequence of if statements
D)    The case structure can be implemented through go to with depending on phrase but without any simple go to
