gtps4m30 | System Generation |
The MSGRT macro is required to specify message router availability and set
message router switches and parameters which apply only to the processor being
generated.
MSGRT must be coded, although all the parameters are optional.
In TPF systems containing the multiple database function (MDBF), message
router support is required only for the basic subsystem generation and is not
to be included when generating any other type of subsystem.
Format
- MAXAP=n
- Specifies the maximum number of user applications that the user is ever
expected to define.
The valid range is 1 to 256-(m+s). Default is 256-(m+s).
- m
- The number of fixed system applications, which is equal to:
2 × (number of systems in the network) + 1.
- s
- The number of optional system applications, equal to 1 if airline's
reservation package is specified via the RES parameter of the MSGRTA
macro. Otherwise, equal to 0.
- Note:
- The number of entries created in the RCAT table is based on the total number
of applications. This includes the user applications specified by the
MAXAP parameter, plus the number of fixed and optional system applications as
defined above.
- COMEXIT=NO|YES
- Specifies whether or not a user-written routine will be invoked for every
input message processed by the message router package.
- Note:
- Inclusion of this macro causes the unsolicited message package to be included
in the system.
Examples
None.
