In Cobol, they had a serious concern for memory size. So they came up with a method known as BCD (Binary Coded Decimal), where a decimal value was converted to binary to save space.

What is the difference between cobol-74 and cobol-85?

COBOL-85 is a later version of COBOL language. COBOL-85 also known as VS COBOL-II provides more features than COBOL-74. Some of the features of COBOL-85 are: 1. In COBOL-85 we can use following delimiters such as END-IF, END-PERFORM,END-STRING,etc. 2. We can use EVALUATE verb in place of complex IF structures. 3. CALL statement can pass variables by CONTENT and BY reference. In COBOL-74 we can only use pass by reference. 4. A new verb CONTINUE is introduced in order to over come the limitations of NEXT SENTENCE verb. 5. COBOL - 85 supports 32 bit addressing mode. UR'S Rj


What is packed decimal?

Packed decimal is a method used in computing to store more in less space. A bit of theory here. Characters are stored in binary in their ASCII representation, such that the number 1 = ascii 49 (decimal). Packed decimal means you can store two numbers (numbers only) in the same space, so that ascii 49 = numbers 4 and 9. There is overhead so it is always a trade off between space and computing. And storage is cheap these days

If you are working in a software company and are in cobol with unix and oracle project what would your career growth be if you got trained in mf cobol?

The most important thing here is to know that unix and cobol is a good platform to work in that to with Oracle as the database. The mf cobol is almost a standard cobol that is followed these days, and many banks want to migrate to this version of cobol(as it is perfectly suited to Unix systems) the another version which is quite popular is IBM cobol this one is more popular with the mainframes community since Ibm is the leader here and it was good move to have there own cobol. so if you are assotiated with unix and not with mainframes then mf cobol is suited with u and most of the middle east and European banks are on unix . but if u want to switch to mainframes then go for IBM cobol. A bit of C language knowledge would certainly be a positive point in your resume.
