1 SET

    This command is a nonprinting directive.  The following
    types of SET commands are available:

        SET CPU
        SET LOG
        SET NOLOG
        SET OUTPUT
        SET PROCESS
        SET RMS

2 CPU

	SET CPU cpu_id

    Selects a CPU to become the new "SDA current CPU".  The CPU is
    specified by its hexadecimal CPU ID, a value between 00 and 1F.
    SET CPU also changes SDA process context.  The new "SDA current
    process" is the current process on the specified CPU.  If there
    is no current process on the new "SDA current CPU", then the
    "SDA current process" is undefined, and no process context
    information will be available until SDA process context is set
    to a specific process.

    Subsequent SDA commands display information based on both the new
    "SDA current process" and new "SDA current CPU".

    Type HELP PROCESS_CONTEXT for specific information about the
    "SDA current process".  Type HELP CPU_CONTEXT for specific
    information about the "SDA current CPU".

    Note:   SET CPU is only valid when analyzing a crash dump.  It is not
            a valid command when analyzing the running system, because
            all the CPU-specific information may not be available.

2 LOG

	SET LOG [file-spec]

    Sends a copy of all subsequent output to the file specified.
    In addition, all subsequent output continues to be sent to SYS$OUTPUT.
    If no file is specified, the default file is SYS$OUTPUT.
    This remains in effect until you issue a SET NOLOG command.

2 NOLOG

	SET NOLOG

    Stops SDA from sending a copy of subsequent commands and output
    to the file specified by the previous SET LOG command.  All
    subsequent commands and output will only be sent to SYS$OUTPUT.

2 OUTPUT

	SET OUTPUT [file-spec]

    Sends all subsequent output to the specified file.  None of the
    subsequent output is sent to SYS$OUTPUT.  This remains in effect
    until you issue another SET OUTPUT command.  To redirect output
    to your terminal, issue a SET OUTPUT command specifying SYS$OUTPUT
    as the file-spec.

    The default file specification is SYS$DISK:[default-dir]SYSDUMP.LIS.

2 PROCESS

        SET PROCESS  name
		    /qualifier

    Selects a process to be used as the new "SDA current process".
    If the specified process is the current process on some CPU, SDA
    also performs an implicit SET CPU command.

    Subsequent SDA commands display information based on both the new
    "SDA current process" and new "SDA current CPU".  Type HELP
    PROCESS_CONTEXT for specific information about the "SDA current
    process".  Type HELP CPU_CONTEXT for specific information about the
    "SDA current CPU".

    The process name must be a quoted string if it contains characters other
    than capital letters, numbers, dollar signs ($), or underscores (_).
    The maximum size of the process name is 15 characters.

    For example:

	SET PROCESS OPCOM    ! Select process OPCOM as "SDA current process"
	SET PROCESS "Batman" ! Select process Batman as "SDA current process"

3 /INDEX=n

    Specifies the new current process by the index into the system's
    list of software process control blocks (PCB).  Alternatively, this
    argument can be the process identification (EPID or PID) longword,
    from which SDA extracts the correct index.

3 /SYSTEM

    Specifies the new current process by the system process control block.  
    The system PCB and process header (PHD) are dummy structures that are 
    located in system space and contain the system working set, global 
    section table, global page table, and other system-wide data.

2 RMS

	SET RMS=option-spec

    Allows specification of control blocks to be displayed by the 
    SHOW PROCESS/RMS command.  The option-spec has the form

    	option    or     (option1,option2,....optionn)

    where option may be

    		ALL [:ifi]	Display all control blocks (default)
    		[NO] ASB	Asynchronous Save Block
    		[NO] BDB	Buffer Descriptor Block
    		[NO] BDBSUM	BDB Summary Page
    		[NO] BLB	Buffer Lock Block
    		[NO] BLBSUM	BLB Summary Page
    		[NO] CCB	Channel Control Block
    		[NO] DRC	Directory Cache
    		[NO] FAB	User File Access Block
    		[NO] FCB	File Control Block
    		[NO] FWA	File Work Area
    		[NO] GBD	Global Buffer Descriptor
    		[NO] GBDSUM	GBD Summary Page
    		[NO] GBH	Global Buffer Header
    		[NO] GBSB	Global Buffer Synchronization Block
    		[NO] IDX	Index Descriptor
    		[NO] IFAB [:ifi] Internal Fab
    		[NO] IFB [:ifi]	Internal Fab
    		[NO] IRAB	Internal Rab
    		[NO] IRB	Internal Rab
    		[NO] JFB	Journal File Block
    		[NO] NAM	Name block
    		[NO] NWA	Network Work Area
    		[NO] RAB	User Rab
    		[NO] RUB	Recovery Unit Block
    		[NO] RUFB	Recovery Unit File Block
    		[NO] RUSB	Recovery Unit Stream Block
    		[NO] RLB	Record Lock Block
    		[NO] SFSB	Shared File Synchronization Block
    		[NO] WCB	Window Control Block
    		[NO] XAB	User Extended Attributes Block
    		[NO] *		Current (as opposed to "new") option
    				specification (includes ifi value)

	 ifi => expression      IFI value (internal file identifier)

	     All (default)      Use of this parameter restricts the
			        display to the selected control blocks
			        for only the file specified by the IFI
			        value.
