SAR$ READ 17.2.3.1. Open-Input Procedure Call (S$AROPENI) The READ packet and data area must be initialized before any images are read. The S$AROPENI PROC performs the READ packet initialization. Initial Conditions The calling program sets the following parameters in the READ packet to appropriate values before calling S$AROPENI: • Required parameters (described in 17.2.1.1) SR$PKTVER SR$INPBUFL SR$FIPADDR SR$IMGBUF SR$INPBUF SR$IMGBUFL • Optional parameters (described in 17.2.1.2) SR$SELLST SR$UNTRFLG SR$SELLSTL SR$LNUMFMT SR$REQTYPE SR$SDFCNTL Calling Format S$AROPENI rpkt error return normal return where rpkt is a label identifying the starting address of the READ packet and data area. Note: It is recommended that the calling program zero-fill the READ packet before placing any parameters in the packet. Returns If the error return from S$AROPENI is taken, A1 contains the call status code, A2 contains the I/O status code, and A3 contains the substatus code. These status codes are also returned in the packet fields SR$CALLST, SR$IOSTAT, and T1 of SR$STATUS, respectively. See 17.2.4 for an explanation of the status codes. If the normal return from S$AROPENI is taken, the initialization of the READ packet is successful. 17–28 7833 1733–004
17.2.3.2. Read Procedure Call (S$ARREAD) SAR$ READ The S$ARREAD PROC returns one image from the symbolic input to the calling program, placing the character text in the text buffer and the attributes in the attribute table. Initial Conditions The calling program sets the following parameters in the READ packet to appropriate values before calling S$ARREAD: • Required parameters (described in 17.2.1.1) SR$TEXBUF SR$ATTRIBL SR$TEXBUFL SR$ATTRIB • Optional parameters (described in 17.2.1.2) SR$ADDRSEC SR$SELLSTL SR$ADDRWO SR$SELLST Calling Format S$ARREAD rpkt error return end-of-file return normal return where rpkt is a label identifying the starting address of the READ packet and data area. Returns Each call to S$ARREAD reads one image from the input. If the normal return is taken, S$ARREAD returns the character text in the text buffer, the attributes in the attribute table, and other information in the READ packet. S$ARREAD does not space-fill the text buffer if the text length is shorter than the text buffer length. If the text length is longer than the text buffer, S$ARREAD truncates the text to the length of the text buffer and takes the error return. See 17.2.1.3 for a list of the fields that contain information returned by S$ARREAD to the calling program. If the error return from S$ARREAD is taken, A1 contains the call status code, A2 contains the I/O status code, and A3 contains the substatus code. These status codes are also returned in the packet fields SR$CALLST, SR$IOSTAT, and T1 of SR$STATUS, respectively. See 17.2.4 for an explanation of the status codes. If the end-of-file return from S$ARREAD is taken, the last read request encountered an end-of-file condition. A1 contains the call status code, A2 contains the I/O status code, and A3 contains the substatus code. These status codes are also returned in the packet fields SR$CALLST, SR$IOSTAT, and T1 of SR$STATUS, respectively. 7833 1733–004 17–29
