10 Working With Mapping Services
106160 Tandem Computers Incorporated 10–1
This section discusses the service provided by NonStop NET/MASTER Management
Services (MS) called Mapping Services. This service enables the manipulation of data
by NCL processes regardless of structure or format. The section discusses the three
components in Mapping Services processing—maps, mapped data object (MDO)
variables, and NCL procedures.
This section does not discuss the structure of standard maps or how to create and use a
user-defined map. These topics are discussed in Section 11, “Standard and
User-Defined Maps.”
Table 10-1 summarizes the verbs discussed in this section. These are verbs that
support access to Mapping Services and data in MDO variables.
Table 10-1. Verbs Used With Maps and MDO Variables
Verbs Description
ASSIGN verb Manipulates multiple variables in a single operation.
DROP verb Deletes (drops) multiple variables in a single operation.
EMS* verbs Controls the flow of Event Management Service (EMS) messages through the

INT* verbs Controls the flow of messages sent from dependent processing environments.
LOG* verbs Controls the flow of messages through the system-level LOGPROC NCL

INT*, EMS*, LOG*, and MSG* refer to all verbs beginning with the letters INT, EMS, LOG, and MSG,
respectively.
For the complete syntax of verbs, refer to the NonStop NET/MASTER NCL Reference
Manual. (In this manual, Section 2, “NCL Summary,” discusses the meaning of the
asterisk (*) following the letters EMS, INT, LOG, and MSG.)
