TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

the GDSX process might run a line-handler task to handle data on the communications lines and
a device-handler task for each server process. The device handlers forward data to the line handler
for forwarding to the remote system.

For further information about designing and coding GDSX processes, refer to the Extended General
Device Support (GDSX) Manual.
Server Program Structure
Example 2 (page 48) illustrates the structure of a single-function server program written in COBOL85.
The program in these example handles data entry for the order-processing application introduced
at the beginning of this section.
NOTE: The program in Example 2 (page 48) illustrates program structure only; it is not a complete
program. For an example of a complete, running Pathway server program, refer to Appendix B,
“Examples” (page 129).
