Execute Form

[DEST=[TRACE | TERM | BOTH],]

Specify the destination of the message. TRACE sends the message to the MVSSERV trace data set. TERM sends the message to the terminal. BOTH sends the message to both the terminal and the trace data set. If you omit this parameter, messages go to the trace data set.

CED=name or address

Specify the name, or address in a register (2–12), of the CED that was passed as input to the invoking program. To map the CED, use the CHSCED macro.

BUFFER=name | address

Specify the name, or address in a register (2–12), of a message buffer that the macro is to issue.

BUFLEN=address

Specify the name, or address in a register (2–12), of a 4-byte field that contains the length in bytes of the message buffer to be issued. The maximum buffer length is 80 bytes. Messages that exceed 80 characters in length are truncated.

[RETCODE=variable]

Specify the name or address of a 4-byte output variable to receive the CHSTRACE return code from register 15. If you omit this parameter, you must obtain the return code from register 15.

MF=(E,plist_address[,COMPLETE])

specifies the execute form of the macro and the address of a storage area for the macro parameter list. The execute form generates code to put the parameters into a parameter list and invoke the desired server.

[,COMPLETE]: MVSSERV performs complete syntax checking, verifying that required CHSTRACE parameters are specified and supplying default values for omitted optional parameters.
