Hello Friends.

I want to know how to create an exe file to run an application developed in Mainframe Platform (using CICS, Db2,COBOL) and give it to the client.
Thank You

The 'Mainframe challenge' forum is, I believe, for setting problems you already know the answer to and seeing how well others answer it. Assuming this is not the case, this question should be in the 'Programming Languages' forum.

It's not entirely clear what you mean. An 'exe' file to me implies a PC/Windows application which you cannot create with mainframe compilers etc.
However, assuming you mean 'a standalone executable file for the mainframe', you can't really do this except for assembler programs and possibly OS/VS COBOL programs if compiled with the NORES option.
All the later versions of COBOL and other languages require an external runtime package - Language Environment for current languages or language specific runtimes like the COBOL II runtimes. There is no facility for including all the relevant modules in one package.
However, assuming your client is on a supported release of OS/390 or z/OS they should have the LE runtimes installed and active, so your program should run OK.
But it is *possible* that if you have written and tested you module against a later version of the LE runtimes than they have got then you program might not run correctly.

If this was not what you were getting at, please explain some more.

Just to add that in some cases it is necessary to ship source and compile it on the client's platform to get it to run correctly. We have some supplied COBOL products where we have to do this as part of the installation. This is one reason why most supplied products which are widely distributed are written in assembler, because they can be supplied in load module form with few problems.
