Question seventy four. What Is The Difference Between A Dynamic And Static Call In Cobol?

Answer :

To correct an in advance solution: All known as modules cannot run standalone if they require software variables surpassed to them through the LINKAGE section. Dynamically referred to as modules are those who are not certain with the calling application at hyperlink edit time (IEWL for IBM) and so are loaded from the program library (joblib or steplib) associated with the job. For DYNAMIC calling of a module the DYNAM compiler option have to be chosen, else the linkage editor will no longer generate an executable as it will count on u deal with resolution of all known as modules. A Statically known as module is one that is sure with the calling module at hyperlink edit, and consequently becomes a part of the executable load module.

Question seventy five. How Can I Tell If A Module Is Being Called Dynamically Or Statically?

Answer :

The ONLY manner is to examine the output of the linkage editor (IEWL) or the weight module itself. If the module is being known as DYNAMICALLY then it will not exist inside the foremost module, if it's far being referred to as STATICALLY then it will likely be seen within the load module. Calling a running storage variable, containing a program call, does now not make a DYNAMIC name. This form of calling is referred to as IMPLICITE calling as the call of the module is implied by means of the contents of the working storage variable. Calling a program call literal.
