Quality is a vital factor for all deliverables in software. This is because of the following reasons: To improve the quality of deliverables To ensure completeness of deliverables To ensure correctness of deliverables To improve maintainability To minimize orientation and study time To make timely delivery To reduce the cost of a task COBOL is a language Oriented towards Business applications.
It is a high level language which is Machine Independent. It is an English like language which is self documenting and so easy to learn, write, read and maintain. Have the working storage variables been initialized? Have the DCL working storage copybooks been included?
Have the DCL indicator variable copybooks been included? If it is a migration program check whether country specific values are correct? Has validation been performed for the input values retrieved from input sources other than the database? Have the working storage and DCL section variables been initialized in the main paragraph of the program?
Has proper documentation if any been given for all the paragraphs? Is essential values been hard coded in the program? Have the cursor variables been initialized before fetch? Have the indicator variables been checked for nullable fields?
In case of abend of an update program check whether the previous transaction alone is rolled backed or the entire set of transactions are rolled back?
Have a check whether the values to be inserted in to the error log table is correct Does the program handle abends by terminating normally with appropriate error message insertion into the error log table.
This is needed so as to track the error and handle appropriately. Have naming conventions been followed?
Does the program check for duplicate conditions while inserting records into the database?
Have all the Working Storage section variables that have been declared been used in the program? To improve performance has it been ensured that sub queries have been avoided?
Has it been ensured that every update operation is preceded by a read operation to check for the existence for the record? In case of data retrieval failure for SQL operations have the values for which the record was not fetched been inserted in to the error log?
If the Program is creating any Report, has it been taken care to handle empty report also? Is there proper checking in the Program to handle empty files? While using user defined words take care that maximum character allowed is 30 characters.
And it can contain only digits, letters and hyphens. Care must be taken that it must not be a reserved word. Also user defined words must have at least one letter and spaces are not allowed. If Numeric Literals are used in program it can contain minimum one digit and maximum 18 digits.
If in the program if the Numeric literal uses a sign it must be used as the left-most character and also there can be only one sign for a Numeric literal. Similarly if decimal is used in the Numerical Literal it cannot be used as the right-most character and also a Numeric Literal can have only one decimal.
If in a program you want to use a quote as a non numeric literal then you must use two continuous quotes to get a single quote. Maximum length that can be used for a non numeric literal is If you want to specify a very high or a very small value in a COBOL program a floating point literal is used and check must be made that it falls between 0.
Columns 1 to 6:1 Paper The SAS INFILE and FILE Statements Steven First, Systems Seminar Consultants, Madison, WI ABSTRACT One of the most flexible features of the SAS system, is its ability to read and write just about any kind of raw file. I have a COBOL indexed file that was built without COBOL.
Now I have to create an FD to open and read the records in COBOL. A record has a key-part that has a fixed length. The 10th class session will start with an analysis of COBOL assignment 5 If part of a variable length record, it should be in the fixed portion of the record.
To add an entry to the end of a variable length table, Check if the table is already at the max, if not;. variable-A is described as PIC X(10). Records in the file contain text which is right-justified.
There may or may not be leading spaces. There may or may not be spaces between the characters. I need to move the contents to variable-B, which is PIC X(20).
move to field "justified LEFT" Quote: >Now do it for a variable pitched font: > This. COBOL is an endangered language. But it once ran 80% of the world's business systems: thousands of mission-critical applications that still exist today. In COBOL comp-3 fields (and in most other languages) this nybble is reserved for the sign whether or not the field is denoted as a signed field in the COBOL PIC.
Comp-3 packed fields are aligned on byte boundaries, and the field is always a whole number of bytes.
