Java and c are programing language used to code system programing but cobol is mainly used for buisiness applications in which there is no question of
platform.Cobol cannot be used in the system programing

know me if i am wrong

Hi,
COBOL Purely a Business language. It can't be used to code any system program.


Know me if am wrong.
Thank you,

muthukannan -

Please check your resources again. I've seen many system programmers using COBOL for their needs; from the other hand, there are many business application written in Java and C.

Poppycock icon_rolleyes.gif
C is the system code for unix, I doubt much about Java and COBOL is more oriented to business applications but generally once it has been compiled it is all equivalent to assembler, i.e., machine specific code.

Uncompiled COBOL is almost platform independant.

The major platform dependency lies in the input-output section, the program's interface with the hardware.

Cobol written without taking advantage of the compiler's extentions should compile under most if not all compilers and run on most if not all platforms.

well as per my knowledge cobol can not be used for developing system applications....coz there are no provisions for hardware interactions like in c we can use assembly language using ASM option in the coding sheet....so it is possible to opreate hardwares through language commands....correct me if i am wrong....

What does this have to do with platform independence?

Just about all things doable can be done with COBOL, maybe not the best tool for some things but doable.

What "hardware interactions" are you referring to?

COBOL can also use assembly language.

COBOL pgms cannot modify system cntl blks and data areas.

Only recently, with the advent of the POINTER facility has COBOL been able to access (but not modify) system cntl blks, etc.

So I'd have to agree that COBOL doesn't lend itself to syspgming. Assembler is the tool of choice for that in the current zOS environment.

No program can be platform independent even java is not platform independent without JVM . So without a virtual machine to run that program it will not be a platform independent language

william uncompiled program is like a text in text editor there is no question for platform for a text

Also cobol is not a platform independent language
