Format

HELP [command-name]

Parameter

command-name
Command for which you need information.
You can also specify the following keywords in place of command-name.

Keyword Function

CPU_CONTEXT Describes the concept of CPU context as it governs the behavior of SDA in uniprocessor and multiprocessor environments

EXECUTE_COMMAND Causes SDA to execute SDA commands contained in a file

EXPRESSIONS Prints a description of SDA expressions

INITIALIZATION Describes the circumstances under which SDA executes an initialization file when first invoked

OPERATION Describes how to operate SDA at your terminal and by means of the site-specific startup procedure

PROCESS_CONTEXT Describes the concept of process context as it governs the behavior of SDA in uniprocessor and multiprocessor environments

SYMBOLS Consists of up to 31 letters and numbers, and can include the dollar sign ($) and underscore (_) characters. When you invoke SDA, it reads in the global symbols from symbols table psect of SYS$BASE_IMAGE.EXE, and from REQSYSDEF.STB, a required subset of the symbols in the file SYSDEF.STB. You can add other symbols to SDA's symbol table by using the DEFINE and READ commands.

READ

Loads the global symbols contained in the specified object module into the SDA symbol table.

Format

READ {/EXECUTIVE directory-spec| [RELOCATE=expression]|filespec}

Parameter

filespec
Name of the device, directory, and file that contains the object module from which you want to copy global symbols. The filespec defaults to SYS$DISK:[default-dir]filename.STB, where SYS$DISK and [default-dir] represent the disk and directory specified in your last SET DEFAULT command. You must specify a file name.

Qualifiers

/EXECUTIVE directory-spec
Reads into the SDA symbol table all global symbols and global entry points defined within all loadable images that make up the executive. (See Table SDA-13 for a list of those images.)
The directory-spec is the name of the directory containing the loadable images of the executive. This parameter defaults to SYS$LOADABLE_IMAGES.
/RELOCATE=expression
Adds the value of expression to the value of each symbol in the symbol table file to be read. You can use the /RELOCATE qualifier only if you also specify a filespec. The /RELOCATE qualifier is useful for examining images that are position independent and are loaded at a base of zero.

Description

The READ command symbolically identifies locations in memory for which the default symbol table (SYS$SYSTEM:SYS.STB) provides no definition. In other words, the required global symbols are located in modules that have been compiled and linked separately from the executive.⁵
The object module file specified in the READ command can be one of the following:

Output of a compiler or assembler (for example, an .OBJ file)
Output generated by the linker qualifier /SYMBOL_TABLE (for example, an .STB file)

Most often the object module file is a file provided by the operating system in SYS$SYSTEM or SYS$LOADABLE_IMAGES. Many SDA applications, for instance, need to load the definitions of system data structures by issuing a READ command specifying SYS$SYSTEM:SYSDEF.STB. Others require the definitions of specific global entry points within the executive image that are contained within those object modules included in the executive.
Table SDA-12 lists those object module files provided in SYS$SYSTEM. Table SDA-13 lists those loadable images in SYS$LOADABLE_IMAGES that define locations within the executive image.

Examples

#1
SDA> READ SYS$SYSTEM:SYSDEF.STB %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYSEXE]SYSDEF.STB;1

The READ command causes SDA to add all the global symbols in SYS$SYSTEM:SYSDEF.STB to the SDA symbol table. Such symbols are useful when you are formatting an I/O data structure, such as a unit control block or an I/O request packet.

#2
SDA> EXAM/INST EXE$QIO+2;4 EXE$QIO+00002: CHMK #001F EXE$QIO+00006: RET SDA> EXAM/INST V_EXE$QIO %SDA-E-BADSYM, unknown symbol "V_EXE$QIO" SDA> READ/RELOCATE=IO_ROUTINES SYS$LOADABLE_IMAGES:IO_ROUTINES.EXE %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]IO_ROUTINES.EXE;1 SDA> EXAM/INST EXE$QIO+2;4 EXE$QIO+00002: MOVZBL 04(AP),R3 EXE$QIO+00006: CMPB R3,#3F SDA> EXAM/INST V_EXE$QIO+2;4 V_EXE$QIO+00002: CHMK #001F V_EXE$QIO+00006: RET

SDA>  EXAM/INST EXE$QIO+2;4

EXE$QIO+00006:  RET
SDA>  EXAM/INST V_EXE$QIO
%SDA-E-BADSYM, unknown symbol "V_EXE$QIO"
SDA>  READ/RELOCATE=IO_ROUTINES SYS$LOADABLE_IMAGES:IO_ROUTINES.EXE
%SDA-I-READSYM, reading symbol table  SYS$COMMON:[SYS$LDR]IO_ROUTINES.EXE;1
SDA>  EXAM/INST EXE$QIO+2;4
EXE$QIO+00002:  MOVZBL  04(AP),R3
EXE$QIO+00006:  CMPB    R3,#3F
SDA>  EXAM/INST V_EXE$QIO+2;4
V_EXE$QIO+00002:  CHMK    #001F
V_EXE$QIO+00006:  RET

This SDA session shows that the initial examination of the instructions at EXE$QIO+2 and EXE$QIO+6 produces the vector for the system service, not the system service code itself. The subsequent READ instruction brings into the SDA symbol table the global symbols defined for the system's I/O routines, including one that redefines the entry point of the system service to be the start of the routine EXE$QIO. Thus, the second examination of the same memory locations produces the first two instructions in the routine. The READ command creates a special symbol, V_EXE$QIO, that points to the system service vector.

#3

   .

The initial SHOW STACK command contains an address that SDA resolves into an offset from the PAGE_MANAGEMENT module of the executive. The READ command loads the corresponding symbols into the SDA symbol table such that the reissue of the SHOW STACK command subsequently identifies the same location as an offset within a specific page management routine.

#4
READ/EXEC

%SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]RECOVERY_UNIT_SERVICES.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]RMS.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]CPULOA.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]LMF$GROUP_TABLE.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SYSLICENSE.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SYSGETSYI.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SYSDEVICE.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]MESSAGE_ROUTINES.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]EXCEPTION.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]LOGICAL_NAMES.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SECURITY.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]LOCKING.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]PAGE_MANAGEMENT.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]WORKING_SET_MANAGEMENT.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]IMAGE_MANAGEMENT.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]EVENT_FLAGS_AND_ASTS.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]IO_ROUTINES.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]PROCESS_MANAGEMENT.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]ERRORLOG.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]PRIMITIVE_IO.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SYSTEM_SYNCHRONIZATION.EXE;1 %SDA-I-READSYM, reading symbol table SYS$COMMON:[SYS$LDR]SYSTEM_PRIMITIVES.EXE;1

This READ command brings all global symbols defined in the modules of SYS$SYSTEM:SYS.EXE (as listed in Table SDA-13) into the SDA symbol table. Included in its results is the work performed by the READ commands illustrated in the two previous examples. The READ/EXECUTIVE command, however, does not load those symbols contained in the modules described in Table SDA-12.

Note

⁵ SDA extracts no local symbols from the object module.

REPEAT

Repeats execution of the last command issued. On terminal devices, the KP0 key performs the same function as the REPEAT command.

Format

REPEAT

Parameters

None.

Qualifiers

None.

Description

The REPEAT command is useful for stepping through a linked list of data structures or for examining a sequence of memory locations.

This series of FORMAT commands pursues the chain of device data blocks (DDBs) from the system global symbol IOC$GL_DEVLIST. The second FORMAT command is constructed so that it refers to the contents of the address at the current location (see Section 7.2.4 for a discussion of SDA symbols). Subsequently, pressing the KP0 key---or issuing the REPEAT command---is sufficient to display each DDB in the device list.

The first SHOW CALL_FRAME displays the call frame indicated by the current FP value. Because the /NEXT_FP qualifier to the instruction displays the call frame indicated by the saved FP in the current call frame, you can use the REPEAT command to repeat the SHOW CALL_FRAME/NEXT_FP command and follow a chain of call frames.

SEARCH

Scans a range of memory locations for all occurrences of a specified value.

Format

SEARCH [/qualifier] range[=]expression

Parameters

range
Location in memory to be searched. A location can be represented by any valid SDA expression (see Section 7.2). To search a range of locations, use the following format:

m:n Range of locations to be searched, from m to n

m;n Range of locations to be searched, starting at m and continuing for n bytes

expression
Indication of the value for which SDA is to search. SDA evaluates the expression and searches the specified range of memory for the resulting value. For a description of SDA expressions, see Section 7.2.

Qualifiers

/LENGTH={LONGWORD|WORD|BYTE}
Specifies the size of the expression value that the SEARCH command uses for matching. If you do not specify the /LENGTH qualifier, the SEARCH command uses a longword length by default.
/STEPS={QUADWORD|LONGWORD|WORD|BYTE}
Specifies the granularity of the search through the specified memory range. After the SEARCH command has performed the comparison between the value of expression and memory location, it adds the specified step factor to the address of the memory location to determine the next location to undergo the comparison. If you do not specify the /STEPS qualifier, the SEARCH command uses a step factor of one longword.

Description

SEARCH displays each location as each value is found.

Examples

#1
SDA> SEARCH GB81F0;500 60068 Searching from 800B81F0 to 800B86F0 in LONGWORD steps for 00060068... Match at 800B8210 SDA>

The SEARCH command finds the value 0060068 in the longword at 800B8210.

#2
SDA> SEARCH/STEPS=BYTE 80000000;1000 6 Searching from 80000000 to 80001000 in BYTE steps for 00000006... Match at 80000A99 SDA>

The SEARCH command finds the value 00000006 in the longword at 80000A99.

#3
SDA> SEARCH/LENGTH=WORD 80000000;2000 6 Searching from 80000000 to 80002000 in LONGWORD steps for 0006... Match at 80000054 Match at 800001EC Match at 800012AC Match at 800012B8 SDA>

The SEARCH command finds the value 0006 in the longword locations 80000054, 800001EC, 800012AC, and 800012B8.
