gtps4m30System Generation

MSGRT

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.
