Configuration Guide
where program_name is the name of the compiled program, and
master_device_name is the full path of Adaptive Server's master device.
Instead of typing the command at the operating system prompt, you can
add program_name preceding the dataserver command line in the
Adaptive Server RUN_server_name file.
This is an sample script; modify it as necessary.
Note
The following example shows the source code that you can use to increase the
