SAR$ READ SR$SDFICW The image control word for the SDF record read. This field is defined only if input is from an SDF file or element. If bit 1 of SR$SDFICW is set, the image is a control record. If bit 1 of SR$SDFICW is clear, the image is a data record. Bit 1 is the leftmost bit of the field. See the Data Structures Programming Reference Manual for further information on System Data Format (SDF) image control words. SR$ICWTYPE If the image is a control record, this field contains the control record type. If the image is a data record, this field is undefined. SR$ICWLEN If the image is a control record, this field contains the length in words of the control record. If the image is a data record, this field is undefined. SR$ICWCHAR This field contains the image character set type, if applicable for this control record or data record. 17.2.1.4. READ Packet Definition PROC The PROC S$ARRPDEF generates the EQUFs to define the READ packet. The calling program may optionally attach an X-register and a B-register to these EQUFs. This allows the calling program to allocate storage space for the READ packet either statically at assembly time or dynamically at execution time. The calling program may display the EQUF labels by setting the display-flag parameter on the PROC call. This PROC also generates EQUs defining the READ packet current version and word length at labels SR$CURVER and SR$PKTWLEN, respectively. Calling Format S$ARRPDEF x-reg,b-reg,dispflg Parameters x-reg b-reg The X-register to be attached to the READ packet EQUFs. If x-reg is omitted, no X register is attached to the EQUFs. The B-register to be attached to the READ packet EQUFs. If it is omitted, no B register is attached to the EQUFs. 17–26 7833 1733–004
dispflg A flag to display a table of the READ packet EQUFs. If it is set to ‘D’, the field names are displayed; otherwise the field names are not displayed. Example $ASCII $INCLUDE ‘MAXR$’ S$ARRPDEF X9,B2,’D’ SAR$ READ The PROC call S$ARRPDEF of this example generates EQUFs using registers X9 and B2 and displays a description of each packet field. 17.2.2. Buffers and Tables for MASM READ Procedures All buffers and tables must be provided by the calling program. The recommended lengths for the buffers and tables are equated to labels in the S$ARRPDEF PROC. These lengths and labels are listed in Table 17–5. These definitions simplify the creation of required buffers and tables for the calling program. Table 17–5. SAR$: MASM READ Buffer and Table Lengths Label Value SR$INPBUFDL (Input buffer word length) 448 SR$IMGBUFDL (Image buffer word length) 63 SR$TEXBUFDL (Text buffer byte length) 132 SR$ATTRIBDL (Attribute table word length) 40 SR$SELLSTDL (Select list byte length) 4 17.2.3. READ Procedures Called from MASM The MASM procedures for the READ function are • S$AROPENI (open input) • S$ARREAD (read) • S$ARCLOSI (close input) The calling sequences for these procedures are generated by MASM PROCs, contained in the SYSLIB file (SYS$LIB$*SYSLIB) or SYS$*RLIB$. 7833 1733–004 17–27
