This piece of data is called an "argument".
when it is passed by reference
When a module is called, the computer jumps to that module and executes the statement in the module's body. Then, when the end of the module is reached, the computer jumps back to the part of the program that called the module, and the program resumes execution at that point.End
see in object oriented programming, data and function are packed inside one module in which data is only accessible by the function of it's own module and the function is the only way data can interact with other modules.In practical use even the private, public and protected things also came up.
There are several ways to connect Visual Basic 6.0 access databases, but to use module and data environment equipment, one must obtain access to the actual program to download first.
Ideally, modules will have low coupling and high cohesion. Coupling describes the strength of the connection between modules in a program. Loose (or low) coupling occurs when modules do not depend on other modules. One way to control this is by avoiding the use of global variables and reducing the number of variables that are passed between the modules. Another is to limit the depth of module calls (where a module calls another module, that then calls another module, and so on). Cohesion is a measure of how well a module accomplishes the module's purpose. High cohesion implies that all the module's internal statements serve to perform the module's (single) task. In order for modules to work together, there must be some connection between them. The nature of the connection is important because it determines the extent to which the modules are coupled. How are they connected? The best way to connect them is to pass the value of a local variable in one module to a second module through its parameter list. (A local variable is a variable that is defined within a module (not a parameter) is local to that module. The values of local variables are not available outside of the module in which they are declared unless they are passed. Local variables are reset to their default values once control leaves the module in which they are declared.) Another way to share information is through the use of global variables. (A variable that is defined outside of a module and that does not need to be passed to a module to be accessed by it is a global variable. Global variables retain their value once control leaves the module in which they are referenced. ) Because the value of a global variable can be changed by any module without passing, it increases the coupling between modules.

support module provides an auxiliary set of instructions that can be used in conjunction with the main software program. It is not designed to be run by the computer user. Instead, these modules are "called" by the computer program as needed. data module comprises any data that is necessary for a task, but not supplied by the user. An example would be word processing software that checks spelling by comparing the words in a document with the words in a dictionary file of correctly spelled words. The data module here is the dictionary file, which is supplied by the software, not by the user.
Material Management is a functional module ... Its called as SAP MM module
Data marshalling is a method to prepare data for processing or for transport over a network.The packaging of arguments passed to a procedure is called marshalling.
argument
It may access static data, but you have to know what 'static data' means: data, which is local to the current module (not shared with other modules), so if you use the function both from module 'A' and from module 'B', they will use different variables (with the same name).
Stus are nothing but the replacement for the modules which are subordinate to module under test. These dummy modules use subordinate module's interface & do some data manipulation, Print the verification & Return control to the module under test. e.g Suppose I have 3 modules viz, module1,module2 & module3 & I have to test module 2. Module 2 is ready but module3 is not ready so we will create a dummy module for module3 which is called as stub. Also we can say that Stub's are nothing but the called functions. These are also called as test harness tools.
If a module is the sole possessor of a value, it will be passed by value, meaning a copy of the argument will be made and used within the module. This copy will be modified independently of any other modules or the original value.
The command module for Apollo 13 was called Aquarius. The lunar module was called Aquarius.
