No indirect command file default in effect, using DEBUG.COM
DBG> SET ATSIGN MYDISK:[MYDIR.DEBUG].DBG
DBG> SHOW ATSIGN
Indirect command file default is MYDISK:[MYDIR.DEBUG].DBG
BREAK
Causes the debugger to display breakpoints established by the
SET BREAK command. All of the information about each breakpoint
is displayed (i.e., AFTER count, whether or not it was specified
/SILENT, and so on).
Format:
SHOW BREAK
Example:
DBG> SET BREAK/AFTER:3 MAIN WHEN (A .EQ. B)
DBG> SHOW BREAK
breakpoint at routine MAIN
/after: 3
WHEN (A .EQ. B)
CALLS
Causes the debugger to display information about the sequence of
currently active procedure calls. This tells you where you are
in the execution of your program.
The optional parameter n specifies the number of call frames to
be displayed. If you do not specify the parameter n, information
about all call frames is displayed.
Format:
SHOW CALLS [n]
Additional information available:
Parameters
n
Specifies the number of call frames that you wish information
about. If omitted, the debugger displays information about all
call frames.
Example
In the following example we are now at line 117 of routine
PRIMES, which was called from line 141 of routine LISTPRIMES.
The asterisks before the module name indicate that the module is
set.
DBG> SHOW CALLS
module name routine name line rel PC abs PC

SHOW SYMBOL/DEFINED.)
Format: SHOW DEFINE
Example:
! The default is DEFINE/ADDRESS
DBG> SHOW DEFINE
current setting is: DEFINE/ADDRESS
DBG> SET DEFINE VALUE
! Treat all DEFINEs as DEFINE/VALUE
DBG> SHOW DEFINE
current setting is: DEFINE/VALUE
DISPLAY
Causes the debugger to list defined screen displays. The name,
maximum size, screen window, kind, and debug command list (if
any) of the defined screen displays are listed. The displays are
listed in their pasting order with the display that is most
hidden listed first.
With no parameters, /ALL, or *, the names and attributes of all
displays are listed. The debugger also accepts a parameter list
of display names. This list of names can include wildcarded (*)
names, in which case all matching display names are displayed.
Format:
SHOW DISPLAY [/ALL | name [,...]]
Additional information available:
Example
DBG> SHOW DISPLAY
display SRC at H1, size = 64
kind = SOURCE (EXAMINE/SOURCE .%SOURCE_SCOPE\%PC)

DBG> SHOW DISPLAY SRC
display SRC at H1, size = 64
kind = SOURCE (EXAMINE/SOURCE .%SOURCE_SCOPE\%PC)
Parameters
name (optional) - the name of the display you want displayed. If
the "name" parameter is omitted, information is displayed about
all displays. The "name" parameter may contain * as a wildcard.
Example:
SHOW DISPLAY S* - gives information about all displays whose name
begins with S.
EDITOR
SHOW EDITOR displays the action taken by the EDIT command, as set
by the SET EDITOR command.
Example:
DBG> SHOW EDITOR
The editor is SPAWNed, with command line "LSEDIT/START=(n,1)"
DBG> SET EDITOR/CALLABLE_TPU
DBG> SHOW EDITOR
The editor is CALLABLE_TPU, with command line "TPU"
EVENT_FACILITY
Format: SHOW EVENT_FACILITY
Display which run time facility has been selected by the command
SET EVENT_FACILITY. This also displays what event names are
defined by the facility (i.e. what the allowed keywords are on
the command SET BREAK/EVENT=keyword). Currently, the languages
that have event facilities are ADA and SCAN.
Additional information available:
Example:
DBG> SHOW EVENT
event facility is ADA
The general forms of commands to set a breakpoint or tracepoint
on an Ada event are:
SET BREAK/EVENT=event [task[, ... ]] [WHEN(expr)] [DO(comnd[;
... ])]
SET TRACE/EVENT=event [task[, ... ]] [WHEN(expr)] [DO(comnd[;
... ])]
If tasks are specified, the breakpoint will trigger only if the
event occurs for those specific tasks.
Ada event names and their definitions
HANDLED an exception is about to be handled
HANDLED_OTHERS an exception is about to be handled in an
OTHERS handler
TERMINATED a task is terminating (including by abort
or exception)

EXIT_HANDLERS
SHOW EXIT_HANDLERS gives a display of the exit handlers that your
program has declared. The exit handler routines are displayed in
the order that they will be called (i.e., last in, first out).
The routine name is displayed symbolically if possible; otherwise
its address is displayed. The debugger's exit handlers are not
displayed.
Example:
DBG> SHOW EXIT
exit handler at MODNAME\EXIT_ROUT1
exit handler at MODNAME\EXIT_ROUT2

This qualifier modifies the others so that they perform their
operations on the list of states given. For example:
SHOW KEY/STATE=GOLD/DIR will give a list of the keys
defined for the GOLD state.
LANGUAGE
Causes the debugger to display the current language.
The current language is the language last established by the SET
LANGUAGE command or the language established at debugger
start-up.
Supported languages are ADA, BASIC, BLISS, C, COBOL, DIBOL,
FORTRAN, MACRO, PASCAL, PLI, RPG, and SCAN. See "HELP Languages"
for details on the support for each one.
Format:
SHOW LANGUAGE
LOG
Causes the debugger to display the name of the current log file
and to report whether the debugger is writing to that log file.
The current log file is the log file last established by a SET
LOG command or the default log file DEBUG.LOG.
Format:
SHOW LOG
MARGINS
Displays the current source-line margin settings for the display
of source code.
Margin settings are established by the SET MARGIN command. By
default, the debugger sets the left margin to 1 and the right
margin to 255.
Format:
SHOW MARGINS
MAX_SOURCE_FILES
Displays the maximum number of source files that the debugger may
keep open at any one time.
The maximum number of source files that the debugger may keep
open at any one time may be specified using the SET
MAX_SOURCE_FILES command or may be the default value of 5.
Format:
SHOW MAX_SOURCE_FILES
MODE
Causes the debugger to display the current radix mode and the
current symbolic or nosymbolic mode.
The current modes are the modes last established by the SET MODE
command or the default modes associated with the current
language.
Format:
SHOW MODE
MODULE
SHOW MODULE provides a formatted alphabetized display giving
information about all the modules in your program. "SHOW MODULE
modname" displays information only about the module named
"modname". The name may contain wildcards (*).
Included in the display is a column telling you whether the
module is set, and a column telling you how many bytes are
required to set the module. At the bottom of the display is a
number which tells you how many bytes remain in the debugger's
memory pool. This can be expanded with the ALLOCATE command.
Format:
SHOW MODULE [/qualifiers] [name]
Additional information available:
Parameters
name (optional) - the name of the module you want displayed. If
the "name" parameter is omitted, information is displayed about
all modules. The "name" parameter may contain * as a wildcard.
Example:
SHOW MODULE DBG* - gives information about all modules whose name
begins with DBG.
Example:
DBG> SHOW MODULE
module name symbols size

X2 no 1520
X3 yes 396
total PASCAL modules: 3. remaining size: 35928.
Qualifiers
Additional information available:
/NORELATED/NOSHARE/RELATED/SHARE
/NORELATED
(ADA only) This is the default. It specifies that no information
about related modules is to be output.
/NOSHARE
This is the default. It specifies that shareable image modules
not be included in the SHOW MODULE output.
/RELATED
(ADA only) This qualifier tells DEBUG to output information about
those modules that are related to each module that is normally
displayed. It lists the relationship of each of these
subordinate modules to the main module along with the normal
information you get with each module. ADA packages and ADA
subunits are the language constructs which give rise to
relationships between modules.
/SHARE
This tells DEBUG to include shareable images in the SHOW MODULE
display (e.g., SHARE$LIBRTL, SHARE$FORRTL). By default, these
are omitted since there is only limited support for debugging
shareable images.
OUTPUT
Says whether or not the debugger is displaying output on the
terminal (term or noterm), whether or not the debugger is writing
output to a log file (log or nolog), and whether or not the
debugger echos commands from command procedures and DO clauses
(verify/noverify).
Format:
SHOW OUTPUT
RADIX
Causes the debugger to display the current radix settings. The
current input radix and the current output radix will be
displayed. Radix may be one of BINARY, OCTAL, DECIMAL, or
HEXADECIMAL.
SCOPE
Causes the debugger to display the current scope search list,
that is, the scope search list established by the last SET SCOPE
command.
The current scope search list designates one or more program
locations (specified by pathnames and/or other special
characters) to be used in the interpretation of symbols that are
specified without pathname prefixes in debugger commands.
Format:
SHOW SCOPE
SEARCH
Displays the current SEARCH parameters.
Current SEARCH parameters are either established by the SET
SEARCH command or are the default values ALL and STRING.
SEARCH parameters determine whether the debugger searches for all
occurrences (ALL) of the string or only the next occurrence
(NEXT) of the string, and whether the debugger displays any
occurrence of the string (STRING) or only those occurrences in
which the string is not bounded on either side by a character
that cannot be part of an identifier in the current language
(IDENTIFIER).
Format:
SHOW SEARCH
SELECT
Shows the current screen display select settings as set by the
SELECT command.
Format:
SHOW SELECT
SOURCE
Displays the source directory search list(s) currently in effect.
The SET SOURCE/MODULE=modname command establishes a source
directory search list for a particular module. The SET SOURCE
command establishes a source directory search list for all
modules not explicitly mentioned in a SET SOURCE/MODULE=modname
command.
If a directory search list has not been established by means of
the SET SOURCE or SET SOURCE/MODULE=modname commands, the SHOW
SOURCE command indicates that no directory search list is
currently in effect. In this case, the debugger expects each
source file to be in the same directory as it was in at compile
time.
Format:
SHOW SOURCE [/EDIT]
Additional information available:
Qualifiers
Additional information available:
/EDIT
Shows the directory search lists that were established with SET
SOURCE/EDIT.
STACK
Displays information from the current call stack. For each
frame, information such as the condition handler and saved
register values is displayed.
Format:
SHOW STACK [n]
The optional argument "n" specifies how many frames to display.
If it is omitted, information about all stack frames is
displayed.
Additional information available:
Example
DBG> SHOW STACK
stack frame 0 (2146814812)
condition handler: 0
SPA: 0
S: 0
mask: M<R2>
PSW: 0000 (hexadecimal)
saved AP: 7
saved FP: 2146814852
saved PC: EIGHTQUEENS\%LINE 69
saved R2: 0
argument list:(1) EIGHTQUEENS\%LINE 68+2
stack frame 1 (2146814852)
condition handler: SHARE$PASRTL+888
SPA: 0
S: 0
mask: none saved
PSW: 0000 (hexadecimal)
saved AP: 2146814924
saved FP: 2146814904
saved PC: SHARE$DEBUG+667
Argument List
One part of the output of SHOW STACK (if existing) for each
frame, is the Argument List. It is the list of arguments passed
along with the call to a subroutine.
NOTE: In some cases the list may contain addresses to actual
arguments. In these cases, "DBG> EXAMINE address" will return
these arguments' values.
STEP
Causes the debugger to display the current step conditions.
The current step conditions include: whether the debugger steps
by lines or by instructions, whether the debugger steps "into"
routines in the user program or "over" them, whether source is
displayed on each STEP command (source/nosource), and whether any
output is given on each STEP command (silent/nosilent).
Current step conditions are the step conditions established by
the last SET STEP command or the default step conditions
established by the current language.
Format:
SHOW STEP
SYMBOL
Displays information about symbols in your program. Using this
command, you can obtain a list of symbols in your program
matching a given namespec, together with type and address
information about the symbols.
Format:
SHOW SYMBOL [/qualifier] namespec [,namespec...]
[IN scope [,scope...]]
Additional information available:
Parameters
namespec
This consists of a single symbol name, or a symbol name that
includes wildcard characters. "*" is the wildcard character, and
it can match zero or more characters.
scopespec
Specifies a module, routine, lexical block, or numeric scope. It
has the same syntax as the scope specification in the SET SCOPE
command. This specifies that only those symbols that match the
namespec and are declared within the given scope are to be
selected.
Qualifiers
Additional information available:
/ADDRESS/DEFINED/DIRECT/GLOBAL/LOCAL/TYPE/USE_CLAUSE
/ADDRESS
Directs the debugger to print the address specification for each
selected symbol.
/DEFINED
Displays symbols you have defined with the DEFINE command.
/DIRECT
Select only those symbols that are declared directly in the given
scope, but not those that are declared in nested scopes.
/GLOBAL
Displays only those defined symbols that are defined /GLOBAL.
Only applies to SHOW SYMBOL/DEFINED.
/LOCAL
Displays only those defined symbols that are defined /LOCAL.
Only applies to SHOW SYMBOL/DEFINED.

TASK
(Only valid for ADA multitasking programs).
Using this command, you can obtain a list of individual tasks in
existence and their current state. Alternatively, you can obtain
information on the entire multitasking system. The type of
display is determined by "task information qualifiers". If no
task information qualifer is given, the command displays a brief
one line status report for each task specified.
For those commands which operate on individual tasks, the tasks
of interest can be specified by taskname parameters and/or by
"task selection qualifiers". If neither of these means are used,
the task defaults to the "visible task", %VISIBLE_TASK. (See SET
TASK/VISIBLE and SET TASK/ACTIVE).
Format:
SHOW TASK [/qualifier...] [taskname [,taskname...] ]
Additional information available:
ParametersSelection QualifiersInformation QualifiersExamples
Parameters
taskname
A taskname parameter may be a pathname which designates a task
declared in your program, for example, MY_MAIN\PROG\MONITOR.
A taskname parameter may also be a task ID or psuedo taskname. A
task ID is a unique number that is associated with a task at the
time the task is created. The debugger syntax for specifying a
task ID is "%TASK n", where "n" is a positive decimal integer.
You can see what task IDs are assigned to currently existing
tasks by typing SHOW TASK/ALL.
A psuedo taskname is one of the DEBUG lexical functions
%ACTIVE_TASK, %CALLER_TASK, %NEXT_TASK, or %VISIBLE_TASK. Type
"HELP Lexicals" for more information on these.
The default taskname parameter is %VISIBLE_TASK.
Selection Qualifiers
Task selection qualifiers can be used singly or in combination.
Except for the ALL" qualifier, they can also be used with
taskname parameters. When used in combination, the logical AND
of the selection criterea is applied. This gives the programmer
a powerful and flexible mechanism to select the tasks of interest
from the many tasks a complicated program may create. There are
five ways to indicate what tasks are of interest:
o A task list selects an explicit set of tasks.
o The /ALL qualifier selects all tasks.
o The /PRIORITY, /STATE, and /[NO]HOLD qualifiers can be used
singly or in combination to select all tasks having the
logical AND of the specified criteria.
o The /PRIORITY, /STATE, and /[NO]HOLD qualifiers can be used
with a task list to select from a small set of "interesting"
tasks.
o The visible task is selected by default if no other selection
is specified.
Additional information available:
/ALL
Selects all tasks that currently exist in your program. Taskname
parameters are not permitted.
/HOLD
/HOLD
/NOHOLD
Selects either those tasks that are on HOLD or those tasks that
are not on HOLD (see SET TASK/[NO]HOLD).
If a list of tasknames is given, select from the list those tasks
that satisfy the HOLD criterea. If the taskname parameters are
omitted, select from all tasks in the program those tasks that
satisfy the HOLD criterea (that is, the /ALL qualifier is
implied).
/PRIORITY
/PRIORITY = n
/PRIORITY = (n1,...,nk)
Selects those tasks that have priority n or those tasks that have
one of the priorities (n1,...,nk), where n is a decimal integer
from 0 to 15 inclusive. (VAX Ada specifies subtype PRIORITY to
be INTEGER range 0..15).
If a list of tasknames is given, select from the list those tasks
that satisfy the priority criteria. If the taskname parameters
are omitted, select from all tasks in the program those tasks
that have the given priorities (that is, the /ALL qualifier is
implied).
/STATE
/STATE = s
/STATE = (s1,...,sk)
Selects those tasks that are in state s or those tasks that are
in one of the states (s1,...,sk).
The state s must be one of the following task states:
READY, RUNNING, SUSPENDED, TERMINATED
If a list of tasknames is given, select from the list those tasks
that satisfy the state criteria. If the taskname parameters are
omitted, select from all tasks in the program those tasks that
are in the given state (that is, the /ALL qualifier is implied).
Information Qualifiers
These qualifiers determine what type of information to display.
If no task information qualifer is given, the default is to
display a brief one line status report for each task selected by
other qualifiers, or explicitly given in the list of tasknames.
Additional information available:
/CALLS/FULL/STATISTICS/TIME_SLICE
/CALLS
/CALLS
/CALLS = n
For each selected task, display information about the sequence of
currently active procedure calls, i.e. the call frames on the
stack of that task.
The optional parameter n specifies the number of call frames to
display. The value of n may be a decimal integer in the range 0
through 32767. If the parameter n is omitted, the debugger
displays information about all call frames.
Use of the /FULL qualifier will provide additional information.
/FULL
Display additional information.
The exact function of this qualifier depends on what other
information qualifiers are given. It is meaningfull when used
with /CALL, /STATISTICS, or by itself. When used without any
other information qualifiers, it changes the brief one line
display of the basic task state to a multi-line report of
detailed information.
/STATISTICS
Display tasking statistics for the entire multitasking system.
These statistics include the number of task activations,
terminations, schedulings, blocks, and other information. The
task list and task selection qualifiers must be omitted.
Use of the /FULL qualifier will provide additional information.
/TIME_SLICE
Display the current setting of the value of the Ada pragma
TIME_SLICE. This is the time used by the Ada multitasking system
for round-robin scheduling. It is displayed in seconds as a
fixed point decimal number. (See the command SET
TASK/TIME_SLICE). The task list and task selection qualifiers
must be omitted.
Examples
SHOW TASK
Shows information for the visible task (typically the task that
entered the debugger).
SHOW TASK/ALL/FULL
Shows detailed information for all currently existing tasks.
SHOW TASK/ALL/PRI=(4,5)/STATE=(READY,RUN)/NOHOLD/CALLS=3
