4.  {help nl} now saves the number of iterations in {hi:e(ic)}.

{p 2 6 2}
5.  {help nlogit} used with {help weights} did not correctly check for
    constant weights within groups; this is fixed.

{p 2 6 2}
6.  {help roctab:roctab, detail} could, under exceedingly rare conditions,
    produce incorrect results; this is fixed.  Additionally, a display format
    was changed to better display noninteger values.

{p 2 6 2}
7.  {help ssc} is a new command that lists and installs packages (and files)
    from the Statistical Software Components (SSC) archive, often called the
    Boston College Archive, and provided by
    {browse "http://repec.org":http://repec.org}.

{p 6 6 2}
    {cmd:ssc} is based on {cmd:archutil} by Nicholas J. Cox, University of
    Durham, and Christopher Baum, Boston College.  The reworking of the
    original was done with their blessing and their participation.

{p 2 6 2}
8.  {help stcurve:stcurve, hazard} is no longer allowed after {help stcox}
    since the graph produced was not a true hazard curve.

{p 2 6 2}
9.  {help tabodds}' display format was changed to better display noninteger
    values in the table.

{p 1 6 2}
10.  {help xtivreg} now saves the list of instrumented variables in
     {hi:e(instd)} and the list of instruments in {hi:e(insts)}.

{title:Stata executable(*), all platforms}

{p 2 6 2}
1.  {help matconst:matrix makeCns}, a programmer's command, now allows
    specifying constraints as a matrix or as a list of constraint numbers; see
    help {help matconst}.  This new matrix feature is also inherited by most
    commands that allow the {cmd:constraints()} option, such as {help cnsreg}.
    In those commands, the {cmd:constraints()} option may now be specified
    with a list of constraint numbers, as previously, or the name of a matrix.

{p 2 6 2}
2.  {help mat_put_rr} is a new programmer's command that directly specifies
    the {hi:Rr} matrix to be used in the next replay call of {help test}; see
    help {cmd:mat_put_rr}.

{p 2 6 2}
3.  {help post} has improved error messages to deal with too many or too few
    expression arguments.

{p 2 6 2}
4.  {help program:program drop} (and automatically generated
    {cmd:program drop}s) could cause subprograms to be mistakenly dropped when
    the subprogram had the same name as the main program in the dropped
    module.  This is fixed.

{p 2 6 2}
5.  {help search} now has new option {cmd:sj} which is a synonym to the
    existing option {cmd:stb} that limits the search to the
    {browse "http://www.stata-journal.com":Stata Journal} and Stata Technical
    Bulletin.


{title:Stata executable(*), Windows, dated 27oct2001}

{p 2 6 2}
1.  A workaround has been introduced for an on-going problem in which the
    mouse cannot be used to select text in the Command window under Windows
    2000 or XP.  The workaround is to type {cmd:set cmdtitle off}.  Doing this
    makes the mouse work but causes the window title to disappear, meaning
    moving the window or changing its font is impossible.  Typing
    {cmd:set cmdtitle on} will bring back the title bar along with the mouse
    problem.

{p 6 6 2}
    We are working on a permanent, more elegant fix.  For more information,
    see {browse "http://www.stata.com/support/faqs/win/clickcommand.html"}.


{hline 5} {hi:update 17oct2001} {hline}

{p 2 6 2}
1.  {help bitest}, {help prtest}, {help ttest}, and {help sdtest} now allow
    {cmd:==} to be used wherever {cmd:=} is allowed in their syntax.  The use
    of {cmd:==} in these commands is more consistent with Stata's general
    syntax that treats {cmd:==} as indicating comparison and {cmd:=} as
    meaning assignment.

{p 2 6 2}
2.  {help cc} and {help cci} would not show part of the results when the
    {cmd:exact} option was combined with the {cmd:cornfield}, {cmd:woolf}, or
    {cmd:tb} options.  This is fixed.

{p 2 6 2}
3.  {help testnl} could, on the rare occasion that the derivative with respect
    to a coefficient is nearly zero, try to post a missing value to {hi:e(b)}.
    This is fixed, and a warning message is displayed instead.

{p 2 6 2}
4.  {help xtgls} reported too large of an average number of observations per
    group in the header of its output; this is fixed.


{hline 5} {hi:update 12oct2001} {hline}

{title:Stata executable(*), all platforms}

{p 2 6 2}
1.  In the 01oct2001 update, {help quietly} and {help while} could not be used
    on the same command line interactively.  Rather than typing

           . {cmd:quietly while {c -(}}

{p 6 6 2}
you had to type

            . {cmd:quietly {c -(}}
            .    {cmd:while} ...
            . {cmd:{c )-}}

{p 6 6 2}
This is fixed.


{title:Stata executable(*), Macintosh}

{p 2 6 2}
1.  Under OS X there is a new menu item, {hi:Bring All to Front} in the
    {hi:Window} menu.  This item brings all Stata windows to the front.

{p 2 6 2}
2.  The Enter key on the numeric keypad is now recognized as a carriage
    return.

{p 2 6 2}
3.  When clicking a variable in the Variables window, a space is now output
    before the variable name rather than after.  The 01oct2001 update claimed
    to have fixed this, but did not.

{p 2 6 2}
4.  In OS 10.1, selecting {hi:Minimize} from the {hi:Window} menu after all
    windows had already been minimized resulted in a crash.  This is fixed;
    selecting {hi:Minimize} now restores the Results window.

{p 2 6 2}
5.  Stata now properly uses Internet Config to map non-native Stata file
    extensions to their appropriate applications.  For example, saving a file
    with the extension .html will set the file's type and creator to your
    default Internet browser.  File extension mappings can be set via the File
    Exchange control panel.

{p 2 6 2}
6.  The original Macintosh Menu Manager API did not allow "/" in menu titles
    and so Stata changed slashes to backslashes ("\").  The new Menu Manager
    does allow slashes, and so the substituting of backslashes in menu titles
    has been removed.


{title:Stata executable(*), Stata for 64-bit Sun Solaris}

{p 2 6 2}
1.  Stata for 64-bit Sun Solaris has been under beta test.
    Stata for 64-bit Sun Solaris is now in production and fully supported
    as of this update.


{hline 5} {hi:update 01oct2001} {hline}

{title:Ado-files, all platforms}

{p 2 6 2}
1.  {help arima:predict, dyn()} after {cmd:arima} would sometimes claim that
    some missing values of the prediction were produced when in fact the
    predictions were correctly produced.  This is fixed.

{p 2 6 2}
2.  {help xtgls:xtgls, panel(corr)} would fail when the path name for
    temporary files included spaces.  This is fixed.


{title:Stata executable(*), all platforms}

{p 2 6 2}
1.  {help display}, under rare circumstances, could cause Small Stata to
    crash.  This is fixed.

{p 2 6 2}
2.  {help gr7oneway:graph, oneway box} could cause Stata to crash when the
    variable labels were very long.  This is fixed.

{p 2 6 2}
3.  {help matscore:matrix score}, when the matrix variables had time-series
    operators, could, in extremely rare instances use an incorrect time
    variable.  This could happen if the {help tsset} time variable was changed
    immediately before {cmd:matrix score} and the data were previously
    {cmd:tsset}.  In that case, the previously set time variable would be
    used.  This is fixed.

{p 6 6 2}
    {help mleval} had the same problem and is also fixed.

{p 2 6 2}
4.  The new {help net:net sj} command makes loading files from the new
    {it:{browse "http://www.stata-journal.com/":Stata Journal}}
    easier.  The {it:Journal} begins publication fourth quarter, 2001,
    so {cmd:net sj} does not do anything useful right now.  You can,
    however, experiment with the command using volume 0 issue 0, written
    as 0-0.  "{cmd:net sj 0-0}" shows the files available.
    "{cmd:net sj 0-0 xx0001}" shows a description for the files associated
    with reference number xx0001.  See help {help net}.

{p 6 6 2}
    The command {help net:net stb} is now documented; see help {help net}.
    {cmd:net stb} works similarly to {cmd:net sj}:  Typing "{cmd:net stb 61}"
    shows the contents of STB-61 and typing "{cmd:net stb 61 dm91}" would
    show the software associated with dm91.

{p 2 6 2}
5.  {cmd:translate}, when translating graph files to PostScript
    format, would incorrectly translate characters such as {c a'} and {c a'g}.
    This is fixed.

{p 2 6 2}
6.  The following should have been documented as of the previous, 17sep2001
    executable update:  In rare instances it was possible to shadow the
    definition of an autoloaded subprogram if a program with the same name as
    the subprogram was defined interactively or as an ado-file.  For example,
    if the ado-file {cmd:mymain} defined the subprogram {cmd:mysub} and
    {cmd:mysub} was also defined interactively, then the interactively defined
    version of {cmd:mysub} would be run in all cases, even when called from
    {cmd:mymain}.  This was fixed.


{title:Stata executable(*), Macintosh}

{p 2 6 2}
1.  When clicking a variable in the Variables window, a space was output
    after the variable name rather than before it.  This is fixed.

{p 2 6 2}
2.  Stata will now attempt to resize and move its windows if the display is
    changed to a smaller screen size.

{p 2 6 2}
3.  {help update:update executable}, after downloading and when presenting
    the final instructions for installing the new executable, would sometimes
    display extra (random) characters when referring to the name of the
    Stata executable.  This is fixed.


{title:Stata executable(*), Unix}

{p 2 6 2}
1.  When clicking a variable in the Variables window, a space was output
    after the variable name rather than before it.  This is fixed.

{p 2 6 2}
2.  {help print}, when printing graph files to a PostScript printer,
    would incorrectly print characters such as {c a'} and
    {c a'g}.  This is fixed.


{hline 5} {hi:update 17sep2001} {hline}

{title:Stata executable(*), all platforms}

{p 2 6 2}
1.  Stata now runs ado-files 6 to 9 percent faster than previously.

{p 2 6 2}
2.  When copying-and-pasting into the {help edit:data editor}, Stata could
    become confused as to the character used to delimit cells and paste
    everything into a single cell.  This is fixed.

{p 2 6 2}
3.  {help anova} could cause Stata to crash when used with no right-hand-side
    variables.  This is fixed.

{p 2 6 2}
4.  {help syntax}, used in a program to parse user input, did not properly
    recognize abbreviation rules for options when the option name began with
    an underscore.  Rather than capitalization being taken to indicate minimum
    abbreviation length, it was taken literally and so required the user to
    specify the options in uppercase letters.  This is fixed.

{p 2 6 2}
5.  {help checksum:set checksum} is now set {cmd:off} rather than {cmd:on}
    by default.  This change affects how Stata copies files over the
    Internet, including {help update}, {help net}, and any other command used
    with a filename starting with "{cmd:http://}".

{p 6 6 2}
    Previously, Stata determined whether a checksum file existed at the
    site and, if it did, used the contents of that file to verify the
    error-free download of the original file.  To restore the old behavior,
    you can type "{cmd:set checksum on}".

{p 6 6 2}
    We have made the default {cmd:off} because (1) we are not aware of any
    user actually having errors and (2) some sites in Europe use caching to
    save on I/O to America.  The result is that, when we would post a
    new update at www.stata.com, some sites would update their cache for the
    files themselves but not the checksum files and so Stata would be fooled
    into thinking that downloads had an error.
    This made it impossible for some users to update their Stata.


{title:Stata executable(*), Macintosh}

{p 2 6 2}
6.  Stata for OS X could crash when clicking on the Delete button in the
    data editor.  This is fixed.

{p 2 6 2}
7.  There is now a console version of Stata for OS X.
    For details see {browse "http://www.stata.com/support/osx/#console"}.


{title:Stata executable(*), Unix}

{p 2 6 2}
8.  {help window:window menu append popout sysmenu}, rather than appending
    a new menu to the system menu, mistakenly cleared the system menu
    first.  This is fixed.


{hline 5} {hi:update 06sep2001} {hline}

{p 2 6 2}
1.  {help mfx} now respects the version of the calling program when it
    generates its predictions.

{p 2 6 2}
2.  The regression diagnostic commands {help acprplot},
    {help cprplot}, {help hettest}, {help lvr2plot}, {help ovtest},
    {help rvfplot}, and {help rvpplot} have been extended to work after
    {help anova}.

{p 2 6 2}
3.  {help savedresults:savedresults drop} would produce an error message and
    fail to operate; this is fixed.
