There are at least five 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
Latest Answer : The END Delimiter --> END-READ END-PERFORM ...
A scope terminator brackets its preceding verb, eg. IF .. END-IF, so that all statements between the verb and its scope terminator are grouped together. Other common COBOL II verbs are READ, PERFORM, EVALUATE,
Latest Answer : terminators like END-PEROFRM END-EVALUTE are called explicit scope terminaotr available in COBOL 85. ...
The PERFORM and END-PERFORM statements bracket all COBOL II statements between them. The COBOL equivalent is to PERFORM or PERFORM THRU a paragraph. In line PERFORMs work as long as there are no internal
Latest Answer : In In-line PERFORM the procedure name is omitted. An In-line PERFORM must be delimited by the END-PERFORM statement.SYNTAX: PERFORM ...
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).
Latest Answer : According to this code If "Next sentence" is given the control wil go to the statement after "ADD +1 TO INPUT-COUNT"(control will go to verb following the next period).If "continue "is given control will go to ...
EVALUATE can be used in place of the nested IF THEN ELSE statements.
Latest Answer : EVALUATE statement contrusts a case structure. The explicit scope terminator for EVALUATE is END-EVALUATE. The various cases can be places between the EVALUATE and END-EVALUATE statements. Example:Here SQLCODE is a built in variable name EVALUATE SQLCODE ...

The linkage section is part of a called program that 'links' or maps to data items in the calling program's working storage. It is the part of the called program where these share items
Latest Answer : Each parameter to be accepted or passed by a procedure must be declared in the LINKAGE SECTION.This section lists buffers for data are common to calling and called programs. Calling parameters are set in the Linkage Section of the called programs and ...
A subscript is a working storage data definition item, typically a PIC (999) where a value must be moved to the subscript and then incremented or decremented by ADD TO and SUBTRACT FROM statements. An
Latest Answer : subscript tells the occurance of a table.where as index tells the displacement of the table. subscript is a working storage variale where as index is not a working storage variable. never use both index and subscript combinely ...
Wake up - you haven't been paying attention! It's not possible to pass an index via linkage. The index is not part of the calling programs working storage. Those of us who've made this
Latest Answer : We can pass subscript by linkage section. index cant. ...
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
