SAR$ COM 20.1.3. SAR$ COM Procedure Called from PLUS The SAR$ COM function writes a symbolic image to the operator's console and optionally reads a symbolic image from the operator's console. The calling procedure for the COM function is SAR_COM. The procedure declaration for SAR_COM is contained in the element SAR$COM$DG, in the <strong>SYSLIB</strong> file (SYS$LIB$*<strong>SYSLIB</strong>) or SYS$*RLIB$. This element is obtained with the COPY statement. The module containing the SAR_COM procedure uses the PLSSTACK and is compiled with the G option using the IBJ$ calling sequence. SAR_COM Procedure Call The SAR_COM procedure constructs an image from the output text and output attributes, writes the image to the operator's console, reads an image from the operator's console, and returns the character text and attributes of the image to the caller. Initial Conditions The calling program sets the following parameters in the packet to appropriate values before calling SAR_COM: • Required parameters (described in 20.1.1.1) PACKET_VERSION OUTPUT_TEXT_BUFFER_ADDRESS OUTPUT_TEXT_BUFFER_BYTE_LENGTH INPUT_TEXT_BUFFER_ADDRESS INPUT_TEXT_BUFFER_BYTE_LENGTH • Optional parameters (described in 20.1.1.2) OUTPUT_CHARACTER_TYPE INPUT_REQUEST_TYPE IMAGE_BUFFER_ADDRESS IMAGE_BUFFER_WORD_LENGTH OUTPUT_ATTRIBUTE_TABLE_ADDRESS OUTPUT_ATTRIBUTE_TABLE_WORD_LENGTH INPUT_ATTRIBUTE_TABLE_ADDRESS INPUT_ATTRIBUTE_TABLE_WORD_LENGTH INPUT_SELECT_LIST_ADDRESS INPUT_SELECT_LIST_BYTE_LENGTH CONSOLE_CLASS CONTROL_BITS ADDITIONAL_CONTROL_BITS RUN_ID_FOR_LOGGING ROUTING_CONSOLE ROUTING_INFORMATION 20–8 7833 1733–004
Calling Format PROCEDURE SAR_COM(COM_PACKET_ADDRESS: WORD MACHINE POINTER) IMPORTED (‘SAR$COM$PG’); SAR$ COM Returns SAR_COM returns the calling status in the COM packet field CALL_STATUS. If the status is S'Normal', then the call was successful. The following information is returned by SAR$ to the calling program: • Character text If operator input was solicited, the address of the character text and the length in 9-bit bytes (characters) are returned in the fields INPUT_TEXT_BUFFER_ADDRESS and BYTE_LENGTH_OF_INPUT_TEXT, respectively. The character set type of the image read is the same as the output image character set type. • Attributes If operator input was solicited, the address of the input attribute table and the number of entries are returned in the fields INPUT_ATTRIBUTE_TABLE_ADDRESS and NUMBER_OF_INPUT ATTRIBUTES, respectively. If the status returned from SAR_COM is not S'Normal' or S'End_of_file', then an error has occurred and CALL_STATUS contains the status code. See 20.1.4 for a list of COM function status codes. 20.1.4. Status Lists for PLUS COM Procedure The COM procedure call status codes listed in Table 20–3 may be returned to the calling program in the CALL_STATUS field of the COM packet. These CALL_STATUS codes are for SAR_COM_PACKET_CURRENT_VERSION = 1 and above. A list of all call status codes is available as COM_CALL_STATUS_LIST, an 18-bit status data entity defined in the element SAR$COMPKTD. Table 20–3. SAR$: COM Procedure CALL_STATUS Codes Octal Code Status 0 Normal return from the SAR$ COM procedure. 01 An outdated SAR$ COM packet version is being used. 02 An invalid SAR$ COM packet version is being used. 03 The value for IMAGE_BUFFER_ADDRESS is NULL; an address must be given for the input image buffer. 04 The IMAGE_BUFFER_WORD_LENGTH is zero; a length must be given for the input image buffer. 05 An invalid value is specified for the INPUT_REQUEST_TYPE field. 7833 1733–004 20–9
