Hi,
The method is like this.
DB2 precompile -> CICS transalator -> Compile -> Link -> Bind.
What actually the precompile does is it creates 2 o/p's.
One is the "SQL code commented" COBOL program. The second one is only the SQL code.
Since the COBOL compiler cannot interpret SQL commands and queries, we need to seperate it. Also, we need to compile the SQL code (it's a long procedure where you find optimum paths for data, etc.) in a different manner.
Then there is CICS translator which will change the CICS commands to equivalent COBOL calls.
So after all these conversions, the COBOL compiler can compile code.

Hope it helps.

We Can do either way.

But if we do traslation first, CICS translator tries to recognizes the embeded SQL statements.So the time taken for translation will be more.
So to reduce the translation time we have to do precompilation first.


Thanks &Regards

gvt460, please use real, descriptive topics for your subject. I doubt anyone reading this will know what "haii" is supposed to mean.

I have edited this post to use a more meaningful topic title.
