Would Standalone cobol program need link editing

We know for preparing a COBOL program before it can be executed using a RUN jcl we need to compile it and then link edit it so that we have a load module which can be run using the JCL. “; ; ; ; My question is if we have only one cobol program which is stand alone, then do we need to link edit it before it can be executed. Please give a detailed explaination

#2 does standalone cobol program need to be linkedited

Yes. Even a “standalone” program┬ástill has to interact with the Operating System which is made possible byt the linkedit.

(Reply to #2) #3

You could also just perform a

compile followed by and link and

‘go’ which will not produced a

load module that is stored in

a library. The ‘GO’ step executes the ‘module’ on the

fly.

This might be something one might do during testing.

Once tested/verified you would to want to incur the compile/link process for each

subsequent execution of the

program………….

“Once tested/verified you would to want to incur the compile/link process for each

I suspect this is a typo and should say NOT WANT TO INCUR . . .

Also, it is usually best to compile and link the module to a load module so that testing will be as close to the “real world” as possible.

#5 You always need to pass the

You always need to pass the program through the link editor. There are always externals calls that need linking. If you have a compiled module, just run the linkedit step. That will save a little time.
