BSP$-Program File Basic Service Package 5.2. Example of Using BSP$ The following example uses BSP$ to access a program file: $(2) FCT $RES 43 . File control table ELTTBL $RES 252 . Buffer for element table FILENAME ‘TESTFILE ‘ . Program file name ADDPKT . BSP$ add packet ‘NEWPROGRAM ‘ . Element name + 0 . Word 2 of add packet + 1,0 . Element type (symbolic) ‘VERS-3 ‘ . Element version name + 5,0,1 . Element cycle information + ELTLEN . Sector length of element text + ELTADRR . Address of element text (sector) + 0 . Time and date element added . (filled by BSP$) . . . $(1) DL A6,FILENAME . Get file name DS A6,FCT . Put in top of FCT L,U A0,FCT . Get address of FCT LMJ X11,RFTI$ . Read FTI J BSPERR . Error return . L,U A0,FCT . Get address of FCT L A1,(ELTTBL,252) . Get addr,len of buffer LMJ X11,RPFET$ . Read element table into buffer J BSPERR . Error return . L,U A0,FCT . Get address of FCT L,U A1,ADDPKT . Get address of add packet LMJ X11,ETIA$ . Add the element to the file J BSPERR . Error return . . Write element text, using SDFO (for example) . L,U A0,FCT . Get address of FCT LMJ X11,WPFET$ . Write back the element table J BSPERR . Error return L A7,FCT+7 . Get next write location A,U A7,ELTLEN . Add length of new element S A7,FCT+7 . Put in FCT . L,U A0,FCT . Get address of FCT LMJ X11,WFTI$ . Write back the J BSPERR . Error return . . . 5–34 7833 1733–004
BSP$-Program File Basic Service Package In this example, BSP$ adds an element to a program file. The following two buffers and one packet are required: • FCT is for the file control table • ELTTBL is for the program file element table • ADDPKT is for a packet that holds information about the element to be added The first call to BSP$ reads the file control table. The file control table must be read before any other calls are made to BSP$. The next call to BSP$ is to read the program file element table. This table must be read before elements are added, deleted or searched for. The BSP$ call to ETIA$ adds the element described in the add packet ADDPKT to the contents in the file TESTFILE. The element name is NEWPROGRAM with version name VERS-3. It is a symbolic element, cycle 0, with a maximum cycle limit of 5. ELTLEN is the sector length of the element. ELTADDR is the starting sector address of the element in the file TESTFILE. The calling program must write the actual text of the element to the file using the SDFO routine. When the element is added to the program file element table, the table must be written back to WPFET$. The next write location is updated by adding the element sector length to word 7 of the FCT. A call to WFTI$ writes the updated FTI back to the file. This completes updating of the file. 5.3. LEPF Considerations This section contains additional information, limitations, restrictions, and considerations pertaining to LEPFs and their use. The following are general limitations and restrictions: • LEPFs are first supported by the BSP$ contained in SYSLIB level 76R1. LEPFs are not recognized as program files by any prior SYSLIB level. • The initial implementation of LEPFs is intended primarily for use by MAPPER, as a container for large MAPPER reports (symbolic elements) that have over 262,143 sectors of element text. • Initially, only MAPPER, FURPUR, PCFP, and BSP$ support LEPFs. • Initially, LEPFs are not supported by the Exec, including the ER PFx$ interface and the command line interface (@ADD, @START, @XQT, and so on). • Initially, LEPFs cannot contain procedure elements (element type 1, subtype 035, and element types 2, 3, and 4), relocatable elements (element type 5), and executable elements (element type 6). • Calling programs that are not modified will not recognize LEPFs as program files. This includes programs that call the relocatable version of BSP$, even when they are re-collected with SYSLIB level 76R1 or higher. 7833 1733–004 5–35
