{title:Description}

{pstd}
{cmd:db} is the command-line way to launch a dialog for a Stata command.

{pstd}
The second syntax (which is the same but includes options) is for use by
programmers.

{pstd}
If you wish to allow the launching of dialogs from a help file, see
{help smcl} for information on the {cmd:dialog} SMCL directive.

{pstd}
{cmd:set} {cmd:maxdb} sets the maximum number of dialog boxes whose contents
are remembered from one invocation to the next during a session.  The default
value of {cmd:maxdb} is 50.


{title:Options}

{phang}
{opt debug} specifies that the underlying dialog box be loaded with debug
    messaging turned on.

{phang}
{opt dryrun} specifies that, rather than launching the dialog, {cmd:db} 
    show the commands it would issue to launch the dialog.

{phang}
{opt permanently} specifies that, in addition to making the change right now,
    the {cmd:maxdb} setting be remembered and become the default setting when 
    you invoke Stata.


{title:Remarks}

{pstd}
The usual way to launch a dialog is to pull down the {hi:Data}, {hi:Graphics},
or {hi:Statistics} menu and make your selection from there.  When you know
the name of the command that you want to run, however, {cmd:db} provides a way
to invoke the dialog from the command line.

{pstd}
{cmd:db} follows the same abbreviation rules that Stata's command-line
interface follows.  So, to launch the dialog for {cmd:regress}, you can
type

	{cmd:. db regress}

{pstd}
or

	{cmd:. db reg}
