Sends a message to an API application running simultaneously on the local system.
G32WRITE MSG, LEN
The G32WRITE function sends a message to an API application. The maximum number of bytes that may be transferred is specified by the value returned in register zero (R0) after a successful completion of the G32ALLOC function.
The G32 WRITE function is a HCON API function that can be called by a 370 Assembler applications program.
The G32WRITE function sets register 0 to the following values:
0 | Indicates a normal return; call successful. |
< 0 | Less than 0. Indicates a host API error condition. |
The following 370 Assembler code example illustrates the use of the host G32WRITE function:
L R11,=v(G32DATA) USING G32DATAD,R11 G32WRITE MSG1, LEN1 /* write "Hello" to AIX */ LTR R0,R0 /* check return code */ BE WRITEOK /* if good, go to write */ ( error code ) . . . MSG1 DC C 'HELLO' LEN1 DC AL4(*-MSG1)
The G32WRITE function is part of the Host Connection Program (HCON).
The G32WRITE function requires one or more adapters used to connect to a mainframe host.
