clear	Removes all stops at a given source line.
cleari	Removes all breakpoints at an address.
delete	Removes the traces and stops corresponding to the specified numbers.
status	Displays the currently active trace and stop subcommands.
stop	Stops execution of the application program.

cont	Continues running the program from the current breakpoint until the program finishes or another breakpoint is encountered.
detach	Exits the debug program, but continues running the application.
down	Moves a function down the stack.
goto	Causes the specified source line to be the next line run.
gotoi	Changes program counter addresses.
next	Runs the application program up to the next source line.
nexti	Runs the application program up to the next source instruction.
rerun	Begins running an application.
return	Continues running the application program until a return to the specified procedure is reached.
run	Begins running an application.
skip	Continues execution from the current stopping point.
step	Runs one source line.
stepi	Runs one source instruction.
up	Move a function up the stack.

trace	Prints tracing information.
tracei	Turns on tracing.
where	Displays a list of all active procedures and functions.

Quits the dbx debug program.

edit	Invokes an editor on the specified file.
file	Changes the current source file to the specified file.
func	Changes the current function to the specified function or procedure.
list	Displays lines of the current source file.
listi	Lists instructions from the application.
move	Changes the next line to be displayed.
/ (Search)	Searches forward in the current source file for a pattern.
? (Search)	Searches backward in the current source file for a pattern.
use	Sets the list of directories to be searched when looking for a file.

assign	Assigns a value to a variable.
case	Changes the way in which dbx interprets symbols.
dump	Displays the names and values of variables in the specified procedure.
print	Prints the value of an expression or runs a procedure and prints the return code.
set	Assigns a value to a nonprogram variable.
unset	Deletes a nonprogram variable.
whatis	Displays the declaration of application program components.
whereis	Displays the full qualifications of all the symbols whose names match the specified identifier.
which	Displays the full qualification of the specified identifier.

attribute	Displays information about all or selected attributes objects.
condition	Displays information about all or selected condition variables.
mutex	Displays information about all or selected mutexes.
thread	Displays and controls threads.

Enables or disables multiprocess debugging.

call	Runs the object code associated with the named procedure or function.
print	Prints the value of an expression or runs a procedure and prints the return code.

catch	Starts trapping a signal before that signal is sent to the application program.
ignore	Stops trapping a signal before that signal is sent to the application program.

display memory	Displays the contents of memory.
gotoi	Changes program counter addresses.
map	Displays address maps and loader information for the application program.
nexti	Runs the application program up to the next machine instruction.
registers	Displays the values of all general-purpose registers, system-control registers, floating-point registers, and the current instruction register.
stepi	Runs one source instruction.
stopi	Sets a stop at a specified location.
tracei	Turns on tracing.

alias	Displays and assigns aliases for dbx subcommands.
help	Displays help information for dbx subcommands or topics.
prompt	Changes the dbx prompt to the specified string.
screen	Opens an Xwindow for dbx command output.
sh	Passes a command to the shell for execution.
source	Reads dbx commands from a file.
unalias	Removes an alias.
