PSEND OPEN
Verbs

PSEND OPEN The PSEND OPEN verb makes a Pathway server class available for use by an NCL
process. The NCL process is then able to send request messages to, and receive reply
messages from, the Pathway server class (by using the PSEND SEND verb).
The Pathway server class must be made available for use by NonStop NET/MASTER
MS (by using the PSNDCTL OPEN command) before it can be made available for use
by an NCL process.
PSEND OPEN ID= local-pathsend-id
[ FORMAT={ MAPPED | UNMAPPED } ]
[ MAP= map-name ]
[ PSNDID= system-pathsend-id ]
ID= local-pathsend-id
specifies a local identifier for the Pathway server class being made available and
sets it to be the current Pathway server class. This operand must be entered. In
the absence of the PSNDID operand, NCL treats the ID operand as specifying both
a local and a system identifier.
FORMAT
specifies the structure of the request and reply messages sent to and received from
the Pathway server class.
MAPPED
specifies that the structure of the request and reply messages is mapped. The
MAP operand specifies the name of the map used to describe and interpret the
structure of the reply message only. Symbolic names are used by Mapping
Services to access individual data structures within the reply message.
There is no default map used to map a reply message.
Note If you do not specify the name of the map, then the data is assigned to the stem of the MDO variable that
holds the reply message. If you attempt to access the reply message other than by specifying the stem
name of the MDO variable, the NCL process raises a run-time error.
Before sending a mapped request message, you must use the ASSIGN verb to create and map the MDO
variable that contains the message.
Refer to the NonStop NET/MASTER NCL Programmer's Guide for information on creating and using
maps.
