The INTREAD, INTCONT,
and INTCLEAR Verbs
Three verbs are available to work with messages that arrive in the request and
response queues:
INTREAD
INTCLEAR
INTCONT
Figure 16-13 shows the use of these verbs in a primary processing environment
(although it could be any type of current execution environment).

Reading a Message From a Dependent Queue
You can use the INTREAD verb to read a message from either the request or response
queue.
When the INTREAD verb reads a message it automatically places the text and the
attributes of the message into an MDO variable beginning with the stem &$INT.. The
names of all the structures and substructures contained in the MDO variable begin
with this stem. See Section 10, “Working With Mapping Services,” for a detailed
discussion of MDO variables.
