The work subvolume can be different for each person using the Pathmaker product
and can be changed at any time during a Pathmaker session. The project subvolume
for a project is designated when the project is created. The project subvolume contains
the catalog, and other associated files, for a project. The project subvolume cannot be
changed, unless the entire project is moved.
Main Menu Function Keys. The function keys appearing on the Pathmaker Main Menu
allow navigation to individual Pathmaker screens that are used to perform major
application development tasks. These function keys are described in the listing that
follows:
F1 - Data Definition
The F1 function key is used to access the Data Definition Language (DDL)
product. DDL can be used to add information to the Data Dictionary files in a
Pathmaker catalog describing fields and records in the database and other fields
that an application uses. Defining the data for an application is usually performed
as part of preparing for a Pathmaker application development effort.
SF1 - SQL Table Registration
If an application accesses data stored in NonStop SQL tables, this screen must be
used to identify those tables to the Pathmaker product. This task is usually
performed as part of preparing for a Pathmaker application development effort.
F2 - Requester Definition
This function key leads to a series of screens (including Screen Painter) where
information is specified about a requester in the application. The requester
definition screens are normally used by application developers.
The information entered on the requester definition screens includes:
The type of target terminal operated by the end user
The names of fields displayed on the application screen
The particular function keys available for the end user
The Pathmaker product will use the information provided to create the following:
SCREEN COBOL requester code
A default screen
Note The Screen Painter can be used to modify the default screen created by the Pathmaker product.
F4 - Service Definition
This key leads to a series of screens where information about a service is entered.
These screens are normally used by application developers.
