Application Execution
APPLICATION EXECUTION
To execute an application generated by ENABLE, you must:
1. Supply the data base files to be accessed by the application
2. Establish a PATHWAY system to execute the application
Figure 1-4 illustrates the tasks that you perform to establish a
PATHWAY system and execute an application.
To establish a PATHWAY system and execute an application, you
enter a series of commands described in Section 5. These
commands:
• Create and name a PATHWAY monitor process (PATHMON). PATHMON
controls the interrelations of the processes and devices
within the PATHWAY system. PATHMON maintains information
about the environment of the PATHWAY system in a file called
PATHCTL. PATHMON can report errors and changes in status to a
log file.
• Create a PATHCOM process. PATHCOM, the command interface to
PATHMON, passes the information in the PATHCOM command file
generated by ENABLE to PATHMON. PATHMON stores this
information in the PATHCTL file.
• Tell PATHCOM to execute the application. PATHCOM passes this
information to PATHMON. PATHMON starts a terminal control
process (TCP) using the characteristics described in the
generated PATHCOM command file. The TCP performs application
operations according to the SCREEN COBOL program, provides
general control of the terminal, and sends messages to the
General Server.
When you execute the application, the General Server, which is
provided by ENABLE, accesses and updates the data base and
replies to the TCP.
