System Level Procedures

NCL can be used to write private programs that are executed by command from your OCS windows, or implicitly from options such as the User Services panel.

Another class of NCL process called system level procedures executes exclusively in the NCL processing regions of certain background virtual users. These system level procedures have access to the special information flows that occur within your product region, namely:

• The activity log
• VTAM messages
• EASINET terminal control data
• OCS window traffic
