Correct Answer: Following guidelines to be following while writing Cobol program: - Use ? EVALUATE ? statement for constructing cases - Use scope terminators for nesting - Use in-line Perform statement for writing ?do? constructions - Use Test Before and Test After in the Perform statement while writing Do-While statements
Correct Answer: There are some differences: COBOL II supports structured programming by using in line Performs and explicit scope terminators It introduces new features (EVALUATE, SET TO TRUE, CALL BY CONTEXT, etc) It permits programs to be loaded and addressed above the 16-megabyte line It does not support many old features (READY TRACE, REPORT-WRITER, ISAM, etc) It offers enhanced CICS support
Correct Answer: IDENTIFICATION DIVISION and PROGRAM-ID paragraph are mandatory for a compilation error free COBOL program
Correct Answer: EVALUATE can be used in place of the nested IF THEN ELSE statements
Correct Answer: Supply the DD cards just as you would for files referred to in the main program
Correct Answer: They communicate via service MVS request calls
Correct Answer: An OOK-Rec is a one of a kind record set, used to get to another record set
Correct Answer: No The mode is specified via the SYSCTL DD card in the JCL
Correct Answer: It generates a bind run-unit and binds all the records for the sub-schema the program is referencing
Correct Answer: No difference There is a difference between obtain first and obtain next for an area sweep, but not when current on the owner in a set
