The history of computer development is often referred to in reference to the different generations of computing devices. Cable Tv Management Software Demo more. A generation refers to the state of. I am confused with the rounded in the compute function in cobol. Declaration VARA PIC S99V99 COMP3. VARB PIC S99V96 COMP3. Procedure. MOVE 12. DIVIDE verbs can be done using COMPUTE statement. In COMPUTE statement. Meaning Add Subtract Exponentiation Divide Multiplication. COMPUTE lt data item 1 ROUNDED. ON SIZE ERROR lt imperative statement 1. NOT ON SIZE ERROR lt imperative statement 2. Example 1 COMPUTE WS A WS B WS C WS D. Values in WS B, WS C will be added, WS D value subtracted. WS A. data items values values. WS A 3. 00 8. WS B 8. Arithmetic Operations In Cobol Program' title='Arithmetic Operations In Cobol Program' />To simplify this program, it will be assumed that the first number in the file is an integer which tells the program how many real data points follow. WS C 1. 00 1. WS D 0. It is very important to know the order of evaluation, i. Arithmetic Operations In Cobol Program' title='Arithmetic Operations In Cobol Program' />Q. What are DB2 Storage Areas When you write COBOL Programs, that read data records from Files, and store Output results to a File, you must declare Input and Output.

COMPUT statement. Below table, explains us. Priority 1. Priority 2 or If both appeared, first appeared operator. Priority 3 or If both appeared, first appeared operator. If parentheses appear in the COMPUTE statement, it will override above sequence. Operations within parentheses are performed first. Statement Order of evaluation. WS A 1. 0 2 Exponentiation 1. WS A. WS A 1. Addition executed first and exponentiation follows. This option is available with all arithmetic VERBs and it is optional. COMPUTE WS A 2. When we sum values 2. But in this case. WS A picture clause is 9. WS A contains the value of 4. More desirable value is 4. This can be acheived thru the use of ROUNDED option. COMPUTE WS A ROUNDED 2. WS A contains value of 4. Let take some example to understand this option. WS A PIC 93 VALUE 4. WS B PIC 93 VALUE 8. WS C PIC 93 VALUE 3. COMPUTE WS A WS B WS C. Above statement, add the value in WS B and WS C and store that value in WS A. After execution of above statement WS A contains the value of 1. Because WS A can hold only upto 3 bytes. Please note that, program wont get abended because this overflowtruncation. But value moved to WS A is not correct one. To aviod these kind. But sometimes, programmer may. It is a good practice to use ON SIZE ERROR to catch such. ON SIZE ERROR option can be used with following arithmetic statements. ADD. ON SIZE ERROR. SUBTRACT. ON SIZE ERROR. MULTIPLY. ON SIZE ERROR. DIVIDE. ON SIZE ERROR. COMPUTE. ON SIZE ERROR. COMPUTE WS A WS B WS C. ON SIZE ERROR MOVE ZEROES TO WS A. In above example, If WS A cannot accomodate the result then ZEROES will be. WS A. A size error can occurs in the following ways. When receiving field is not large enough to accommodate the result. When division by zero occurs. If ON SIZE ERROR option becomes true, statements after this option will get executed. These statement needs to be ended either by period OR scope terminator i. ADD, scope terminator is END ADD. TIP Always make sure receiving field has large enough to accommodate the result. NEXT CHAPTER TOPIC COBOL Visit COBOL books section in this site for good books.
