Requesters Using GDSX
When developing a front-end process using GDSX, consider the following points:
•
A GDSX front-end process is a good choice when a specified data communications
protocol is not supported by the Pathway TCP but is supported by GDSX.
•
A GDSX front-end process is also a good choice when performance is critical.
SCREEN COBOL might not be efficient enough to handle a large amount of
application function.
•
A GDSX process can be designed to be context-sensitive, through use of the
context-sensitive Pathsend pseudo-procedures.
•
GDSX processes are managed either through the Subsystem Control Facility (SCF)
interactive interface or through a management application program using the
Subsystem Programmatic Interface (SPI).
For further information about designing and coding GDSX processes, refer to the
Extended General Device Support (GDSX) Manual.
