SAR$ READ The default buffer and table lengths are listed in Table 17–1. Table 17–1. SAR$: PLUS READ Buffer and Table Length Defaults Identifier Value SAR_IO_BUFFER_WORD_LENGTH 448 SAR_IMAGE_BUFFER_WORD_LENGTH 63 SAR_TEXT_BUFFER_BYTE_LENGTH 132 SAR_ATTRIBUTE_TABLE_WORD_LENGTH 40 SAR_SELECT_LIST_BYTE_LENGTH 4 The buffer and table type definitions are listed in Table 17–2. Table 17–2.

READ Procedures Called from PLUS The procedures for the READ function are: • SAR_OPEN_INPUT • SAR_READ • SAR_CLOSE_INPUT The declarations for these procedures are contained in the element SAR$READ$DG, in the <strong>SYSLIB</strong> file (SYS$LIB$*<strong>SYSLIB</strong>) or SYS$*RLIB$. This element may be obtained with the COPY statement. SAR$READ$DG contains all three procedure declarations. All of the READ procedure modules are compiled with the G option, using the IBJ$ calling sequence. 17–12 7833 1733–004
17.1.3.1. SAR_OPEN_INPUT Procedure Call SAR$ READ The READ packet data structure must be initialized before any input images are read. The SAR_OPEN_INPUT procedure performs the READ packet initialization. Initial Conditions The calling program sets the following parameters in the READ packet to appropriate values before calling SAR_OPEN_INPUT: • Required parameters (described in 17.1.1.1) PACKET_VERSION INPUT_FILE_INFO_PKT_ADDRESS INPUT_BUFFER_ADDRESS INPUT_BUFFER_WORD_LENGTH IMAGE_BUFFER_ADDRESS IMAGE_BUFFER_WORD_LENGTH • Optional parameters (described in 17.1.1.2) SELECT_LIST_ADDRESS SELECT_LIST_BYTE_LENGTH REQUEST_TYPE LINE_NUMBER_FORMAT UNTRANSLATE_MODE SDF_CONTROL_RECORDS_TO_PASS Note: It is recommended that the calling program zero-fill the READ packet before placing any parameters in the packet. Calling Format PROCEDURE SAR_OPEN_INPUT (READ_PACKET_ADDRESS: WORD MACHINE POINTER) IMPORTED ('SAR$OPENI$PG'); Returns SAR_OPEN_INPUT returns the initialization status in the packet in CALL_STATUS. If the status is S'Normal', the initialization of the READ packet is successful. Otherwise an error has occurred, and CALL_STATUS contains the status code. See 17.1.4 for a list of the READ function status codes. 7833 1733–004 17–13
