concatinating two rec by using COBOL & JCL
I need to concatenate records by using cobol and jcl (both) as follows. Input File: AAAAA BBBBB CCCCC DDDDD 11111 22222 33333 44444 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 concatinated and so on. and o/p as given below Output File: AAAAA 11111 BBBBB 22222 CCCCC 33333 DDDDD 44444
What is the difference between COPY and INCLUDE
In the example below
05 WS-VAR1 PIC X(5),05 WS-VAR2 REDEFINES WA-VAR1 PIC 9(5),PROCEDURE DIVISION MOVE ‘ABCDE’ TO WS-VAR1.Now what is the value of WS-VAR1 and WS-VAR2 ?
How to remove the duplicate records present in a PS dataset using JCL?
How many bytes occupied following comp example?
Dear Friends, 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 in advance,.

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.
Consider the following COBOL entries
05 X PIC 99 VALUE 10.
COMPUTE X = 3 * X – 40.
The result in X is
(c) Compile or Run time error
(d) none of these
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.
cob2 B.cbl -o B -L
cob2 A.cbl -o A -L
or cob2 A.cbl B.cbl A -L
The following entries appear in the WORKING-STORAGE SECTION:
05 YY PIC XX VALUE 90 .
05 MM PIC XX VALUE 12 .
05 DD PIC XX VALUE :31 .
01 DATE-EDIT PIC XX/XX/XX.
MOVE DATE-TODAY TO DATE-EDIT.
Is there any condition in cobol to check the variable has any special characters?
What is the use and when do we are use comp variables (comp, comp1, comp2 and comp3)?
