New Program wizard

Enter the fields of this wizard to create a Program or the derived instance of a Program.

Project
Select a project in the list or enter the name of the project in which the instance is to be saved.

A project represents the physical distribution of your instances in your workspace. It groups directories and files. It is used to organize resources that can be built, shared, or versioned.

A Pacbase project contains a subset of file that correspond to the models and the generated sources that constitute an application.

Package
A package corresponds to a logical group of information in a project.

If you are maintaining a Pacbase application, selecting a package is not advised. The instance override mechanism is then made easier because the overriding instance is always in the same package as the overridden instance. You do not need to manage the presence of both the instances in the same package, which is the requirement of an override.

Name
Enter the name here. Its maximum length is six characters. It must be constituted of alphabetic or numeric characters only.

If the Derive box is checked, you can use the whole length of the edit field. The name of the derived instance can start with the name of its reference instance. If you have selected a Design derivation, the name can also include the generation Library. If you do not enter a name and specify a reference instance in the Program to derive field, the name is automatically initialized with the name of the reference instance.

Generation parameters
Generation parameters are specified in Libraries. These parameters are related to the adaptation to the operating system in use.

You select the Library by clicking Browse.

Label
Enter the label that identifies the instance. It will constitute a search criterion for a subsequent search.
Open editor on finish
Select this check box if you want to open the editor of the instance you are creating. The editor opens on the Overview tab. From there, you can access the other tabs to specify all the characteristics of the instance.
Derive
Select this check box if you want to create a derived instance that points to a reference instance. The derived instance contains a link to the reference instance and possibly a link to a generation Library. From the derived instance, you can generate the reference instance without duplicating its design. If you select this box, two fields are displayed:
  • Derivation type. Depending on the entity, there can be one or two derivation types:
    • Design derivation is available on Programs, Dialogs/Screens, Server Dialogs/Servers, and Data Structures (for the generation of the Copybooks). With this derivation type, you use the derived instance to generate the reference instance from a different Library, without duplicating its design. The generation parameters of the Library indicated in the derived instance produce a COBOL source different from the source that is generated from the Library of the reference instance.
    • Code derivation is available on entities that can contain specific code: Programs, Screens, and Servers. With this derivation type, you use the derived instance to generate the reference Program, Screen, or Server. The complete source code (the generated code and the specific code) of the reference instance becomes the generated code in the derived instance. Moreover this generated code is reconciled with the specific code of the derived instance. In turn, the derived instance can also become the reference instance for a new derived instance and the same process applies.
  • <Entity> to derive. In the wizard, <Entity> can be Program, Screen, Data Structure, or Dialog. You select the reference instance, that contains the design and, possibly, the specific code that is needed by the derived instance
