INTEGRATING APPLICATIONS
Generating the Applications
GENERATING THE APPLICATIONS
When you generate the applications, you can simplify the process
of integrating them by performing the following tasks:
1. Direct all SCREEN COBOL object code to the same object file.
When the object code for all the applications resides on the
same file, you eliminate the need to modify a portion of the
PATHCOM command file.
2. Obtain a SCREEN COBOL compilation listing for each
application. These compilation listings provide information
that you will need when you modify the PATHCOM command file.
3. Obtain SCREEN COBOL source code for each application that is
to call another. Since ENABLE does not generate applications
that call other applications, you must modify the source code
of the calling application if you want to provide this
capability.
4. Avoid using the same box names for boxes having different
values for the ABILITY attributes, or for boxes that
represent different data base files. Otherwise, you may not
be able to integrate the applications into a single PATHWAY
system.
Directing Object Code to the Same Object File
When you use an ENABLE application, a terminal control process
(TCP) within the PATHWAY system interprets the SCREEN COBOL
object code and sends messages to a server process. A TCP can
obtain SCREEN COBOL object code from several different object
files. If you direct the object code of all applications to a
single object file, however you eliminate the need to identify
these different object files in the PATHCOM command file.
To direct object code to the same object file, you can use either
of the following methods:
1. Generate the applications on the same system, volume, and
subvolume.
2. Supply a value for the SCOBOLOBJECT attribute to identify the
same object file for all applications.
