Step 2: Identify the types of data to support

This step identifies the types of data required by the applications under development for your project. Some examples of the types of data used are source code, object modules, load modules, and source listings. The list of types developed in this step is used in later steps.

SCLM supports the same kind of data supported by MVS™ partitioned data sets. The amount of data is also a factor in determining the types of data needed. Different types (such as objects and listings) of data should not reside in the same SCLM type. Determine the number of types you need based on the data you want to maintain for the project. For example, if you want to maintain compiler listings, a listing type is necessary. At a minimum, use four types to produce executable code:

Source type for application source code
Object type for generated object code
Load type for generated load modules
Architecture type for architecture definition members.

Similar kinds of data can reside in separate types. For example, you can divide source code into assembler source code and Pascal source code. To do this, identify an assembler type and a Pascal type.
