setoptions(option1:value [,option2:value ... ]) option1, option2, ...
  option names
setoptions(str), where str is of the form structure(option1:value, ...)
Type 'usage(options)' for a succinct list of all options and their
   permissible values.

Keywords: control, missing values, output, random numbers
setoptions(keyword:value [,keyword:value, ...]) changes the values of
various items specified by the keywords.

Legal option names are 'angles', 'batchecho', 'dumbplot', 'errors',
'findmacros', 'format', 'fstats', 'height', 'inline', 'labelabove',
'labelstyle', 'maxlinelen', 'maxwhile', 'minpvalue', 'missing', 'nsig',
'prompt', 'pvals', 'quiet', 'restoredel', 'seeds', 'update',
'traceback', 'warnings', 'wformat', and 'width'.

Option name 'lines' is a synonym for 'height' for compatibility with
previous versions.

On versions allowing you to recall previous commands (Macintosh,
Windows, Motif, Unix/Linux, extended memory DOS), options 'history' and
'savehistry' (note spelling) are also available (see gethistory() and

On windowed versions (Macintosh, Windows, Motif), options 'matchdelay'
and 'scrollback' is also legal.

In the Windows version, option 'keyboard' is also legal.

In the Windows and Motif versions, option 'enableitem' is also legal.

On computers such as a Macintosh, with changeable fonts, options 'font'
and 'fontsize' are also legal.

See topic 'options' for details on these options.

setoptions(Options), where Options is a structure with component names
matching any or all of the legal option names, sets the options from the
component values.  For example, if Options was created by 'Options <-
getoptions()', setoptions(Options) resets the options to what they were
at the time getoptions() was invoked.  See also getoptions().

setoptions(defaults:T) restores all the options to their default values.
It is an error if there is more than one argument.  If a prompt was set
at start up, it is restored.  When setoptions(defaults:T) occurs in a
batch file, the current batch prompt is restored to what it was when the
batch file was opened, either the file name or the value of keyword
'prompt' on the batch() command.  See batch().

On a Macintosh, you can use the Options menu to change most of the
options.  This works by generating and executing an appropriate
setoptions() command.
