       Set or display attributes and values for shell parameters.

       A parameter is created for each name that does not already refer
       to one.  When inside a function, a new parameter is created  for
       every  name  (even those that already exist), and is unset again
       when the function completes.  See  `Local  Parameters'  in  zsh-
       param(1).   The  same  rules  apply to special shell parameters,
       which retain their special attributes when made local.

       For each name=value assignment, the parameter  name  is  set  to
       value.  Note that arrays currently cannot be assigned in typeset
       expressions, only  scalars  and  integers.   Unless  the  option
       KSH_TYPESET  is  set, normal expansion rules apply to assignment
       arguments, so value may be split into  separate  words;  if  the
       option  is  set, assignments which can be recognised when expan-
       sion is performed are treated as single words.  For example  the
       command  typeset  vbl=$(echo  one  two) is treated as having one
       argument if KSH_TYPESET is set, but otherwise is treated as hav-
       ing the two arguments vbl=one and two.

       If  the shell option TYPESET_SILENT is not set, for each remain-
       ing name that refers to a parameter that is set,  the  name  and
       value of the parameter are printed in the form of an assignment.
       Nothing is printed for newly-created  parameters,  or  when  any
       attribute  flags  listed  below  are  given along with the name.
       Using `+' instead of minus to introduce an  attribute  turns  it
       off.

       If  no  name  is present, the names and values of all parameters
       are printed.  In this case the attribute flags restrict the dis-
       play   to   only   those  parameters  that  have  the  specified
       attributes, and using `+' rather than `-' to introduce the  flag
       suppresses printing of the values of parameters when there is no
       parameter name.

       If no attribute flags are given, and either  no  name  arguments
       are  present  or  the  flag +m is used, then each parameter name
       printed is preceded by a list of the attributes of that  parame-
       ter  (array, association, exported, float, integer, readonly, or
       undefined for autoloaded parameters not yet loaded).  If  +m  is
       used  with  attribute  flags, and all those flags are introduced
       with +, the matching parameter names are printed but their  val-
       ues are not.

       The following control flags change the behavior of typeset:

       +      If  `+'  appears by itself in a separate word as the last
              option, then the names of all parameters (functions  with
              -f)  are  printed,  but  the values (function bodies) are
              not.  No name arguments may appear, and it  is  an  error
              for  any  other options to follow `+'.  The effect of `+'
              is as if all attribute flags which precede it were  given
              with a `+' prefix.  For example, `typeset -U +' is equiv-
              alent to `typeset +U'  and  displays  the  names  of  all
              arrays  having the uniqueness attribute, whereas `typeset
              -f -U +' displays the names  of  all  autoloadable  func-
              tions.   If  +  is the only option, then type information
              (array, readonly, etc.) is also printed for each  parame-
              ter, in the same manner as `typeset +m "*"'.

       -g     The  -g  (global) means that any resulting parameter will
              not be restricted to local scope.  Note  that  this  does
              not  necessarily  mean that the parameter will be global,
              as the flag will apply to any existing parameter (even if
              unset)  from  an  enclosing function.  This flag does not
              affect the parameter after  creation,  hence  it  has  no
              effect  when  listing  existing  parameters, nor does the
              flag +g have any effect except  in  combination  with  -m
              (see below).

       -m     If  the  -m flag is given the name arguments are taken as
              patterns (use quoting to prevent these from being  inter-
              preted  as  file patterns).  With no attribute flags, all
              parameters (or functions with the -f flag) with  matching
              names are printed (the shell option TYPESET_SILENT is not
              used in this case).

              If the +g flag is combined with -m, a new local parameter
              is  created  for  every  matching  parameter  that is not
              already local.  Otherwise -m applies all other  flags  or
              assignments to the existing parameters.

              Except  when  assignments are made with name=value, using
              +m forces the matching parameters and their attributes to
              be  printed,  even  inside  a  function.  Note that -m is
              ignored if no patterns are given, so  `typeset  -m'  dis-
              plays attributes but `typeset -a +m' does not.

       -p     If  the  -p  option  is  given, parameters and values are
              printed in the form of a typeset command and  an  assign-
              ment  (which  will  be  printed separately for arrays and
              associative  arrays),  regardless  of  other  flags   and
              options.    Note  that  the  -H  flag  on  parameters  is
              respected; no value will be shown for these parameters.

              As the intention of this option is to produce output that
              can  restore  the current state, readonly specials (whose
              values cannot be changed) are not shown  and  assignments
              to  arrays  are  shown  before  the typeset rendering the
              array readonly.

       -T [ scalar[=value] array [ sep ] ]
              This flag has a different meaning when used with -f;  see
              below.   Otherwise  the  -T option requires zero, two, or
              three arguments to be present.  With  no  arguments,  the
              list  of  parameters  created  in  this fashion is shown.
              With two or three arguments, the first two are  the  name
              of  a  scalar  and  of an array parameter (in that order)
              that will be tied together in the  manner  of  $PATH  and
              $path.  The optional third argument is a single-character
              separator which will be used to join the elements of  the
              array  to form the scalar; if absent, a colon is used, as
              with $PATH.  Only the first character of the separator is
              significant; any remaining characters are ignored.

              Only  the  scalar  parameter  may  be assigned an initial
              value.  Both the scalar and the array  may  otherwise  be
              manipulated  as  normal.  If one is unset, the other will
              automatically be unset too.  There is no way  of  untying
              the  variables  without unsetting them, nor of converting
              the type of one of them with another typeset command;  +T
              does  not work, assigning an array to scalar is an error,
              and assigning a scalar to array sets  it  to  be  a  sin-
              gle-element array.

              Note  that  both  `typeset  -xT ...'  and `export -T ...'
              work, but only the scalar  will  be  marked  for  export.
              Setting the value using the scalar version causes a split
              on all separators (which cannot be quoted).  It is possi-
              ble to apply -T to two previously tied variables but with
              a different separator character, in which case the  vari-
              ables  remain  joined  as  before  but  the  separator is
              changed.

       Attribute flags that transform the final value (-L, -R, -Z,  -l,
       -u)  are  only  applied  to the expanded value at the point of a
       parameter expansion expression using `$'.  They are not  applied
       when  a  parameter  is retrieved internally by the shell for any
       purpose.

       The following attribute flags may be specified:

       -A     The names refer  to  associative  array  parameters;  see
              `Array Parameters' in zshparam(1).

       -L [ n ]
              Left  justify  and  remove  leading blanks from the value
              when the parameter is expanded.   If  n  is  nonzero,  it
              defines  the width of the field.  If n is zero, the width
              is determined by the width of  the  value  of  the  first
              assignment.   In  the  case  of  numeric  parameters, the
              length of the complete value assigned to the parameter is
              used  to determine the width, not the value that would be
              output.

              The width is the count of characters, which may be multi-
              byte  characters  if  the  MULTIBYTE option is in effect.
              Note that the screen width of the character is not  taken
              into  account;  if  this  is  required,  use padding with
              parameter expansion flags ${(ml...)...} as  described  in
              `Parameter Expansion Flags' in zshexpn(1).

              When the parameter is expanded, it is filled on the right
              with blanks or truncated if necessary to fit  the  field.
              Note  truncation  can  lead  to  unexpected  results with
              numeric parameters.  Leading zeros are removed if the  -Z
              flag is also set.

       -R [ n ]
              Similar  to  -L, except that right justification is used;
              when the parameter is expanded, the field is left  filled
              with  blanks  or truncated from the end.  May not be com-
              bined with the -Z flag.

       -U     For arrays (but not for associative  arrays),  keep  only
              the  first occurrence of each duplicated value.  This may
              also be set for colon-separated special  parameters  like
              PATH  or FIGNORE, etc.  This flag has a different meaning
              when used with -f; see below.

       -Z [ n ]
              Specially handled if set along with the -L flag.   Other-
              wise,  similar  to -R, except that leading zeros are used
              for padding instead of  blanks  if  the  first  non-blank
              character  is  a digit.  Numeric parameters are specially
              handled:  they  are  always  eligible  for  padding  with
              zeroes,  and  the  zeroes  are inserted at an appropriate
              place in the output.

       -a     The names refer to array parameters.  An array  parameter
              may be created this way, but it may not be assigned to in
              the typeset statement.  When displaying, both normal  and
              associative arrays are shown.

       -f     The  names refer to functions rather than parameters.  No
              assignments can be made, and the only other  valid  flags
              are -t, -T, -k, -u, -U and -z.  The flag -t turns on exe-
              cution tracing for this function; the flag  -T  does  the
              same,  but  turns off tracing on any function called from
              the present one, unless that function also has the -t  or
              -T  flag.   The  -u and -U flags cause the function to be
              marked for autoloading; -U also causes alias expansion to
              be  suppressed  when  the  function is loaded.  The fpath
              parameter will be searched to find the  function  defini-
              tion  when the function is first referenced; see the sec-
              tion `Functions'. The -k and -z flags make  the  function
              be   loaded  using  ksh-style  or  zsh-style  autoloading
              respectively. If neither is given,  the  setting  of  the
              KSH_AUTOLOAD   option  determines  how  the  function  is
              loaded.

       -h     Hide: only useful for special  parameters  (those  marked
              `<S>' in the table in zshparam(1)), and for local parame-
              ters with the same name as a  special  parameter,  though
              harmless  for  others.   A  special  parameter  with this
              attribute will not retain its special  effect  when  made
              local.  Thus after `typeset -h PATH', a function contain-
              ing `typeset PATH' will create an ordinary local  parame-
              ter  without the usual behaviour of PATH.  Alternatively,
              the local parameter may itself be given  this  attribute;
              hence  inside  a  function  `typeset  -h PATH' creates an
              ordinary local parameter and the special  PATH  parameter
              is not altered in any way.  It is also possible to create
              a local parameter using `typeset +h special',  where  the
              local  copy of special will retain its special properties
              regardless of having the -h  attribute.   Global  special
              parameters  loaded from shell modules (currently those in
              zsh/mapfile and zsh/parameter)  are  automatically  given
              the -h attribute to avoid name clashes.

       -H     Hide  value:  specifies that typeset will not display the
              value of the parameter when listing parameters; the  dis-
              play for such parameters is always as if the `+' flag had
              been given.  Use of the parameter is  in  other  respects
              normal, and the option does not apply if the parameter is
              specified by name, or by  pattern  with  the  -m  option.
              This   is  on  by  default  for  the  parameters  in  the
              zsh/parameter and zsh/mapfile  modules.   Note,  however,
              that  unlike the -h flag this is also useful for non-spe-
              cial parameters.

       -i [ n ]
              Use an internal integer representation.  If n is  nonzero
              it  defines  the  output arithmetic base, otherwise it is
              determined by the first assignment.  Bases from 2  to  36
              inclusive are allowed.

       -E [ n ]
              Use an internal double-precision floating point represen-
              tation.  On output the variable will be converted to sci-
              entific  notation.  If n is nonzero it defines the number
              of significant figures to display; the default is ten.

       -F [ n ]
              Use an internal double-precision floating point represen-
              tation.   On  output  the  variable  will be converted to
              fixed-point decimal notation.  If n is nonzero it defines
              the  number of digits to display after the decimal point;
              the default is ten.

       -l     Convert the result to lower case whenever  the  parameter
              is expanded.  The value is not converted when assigned.

       -r     The  given  names are marked readonly.  Note that if name
              is a special parameter, the  readonly  attribute  can  be
              turned on, but cannot then be turned off.

              If   the  POSIX_BUILTINS  option  is  set,  the  readonly
              attribute is more restrictive:  unset  variables  can  be
              marked  readonly and cannot then be set; furthermore, the
              readonly attribute cannot be removed from  any  variable.
              Note that in zsh (unlike other shells) it is still possi-
              ble to create a local variable of the same name  as  this
              is considered a different variable (though this variable,
              too, can be marked readonly).

       -t     Tags the named parameters.  Tags have no special  meaning
              to  the  shell.   This  flag has a different meaning when
              used with -f; see above.

       -u     Convert the result to upper case whenever  the  parameter
              is  expanded.   The value is not converted when assigned.
              This flag has a different meaning when used with -f;  see
              above.

       -x     Mark  for  automatic  export to the environment of subse-
              quently executed commands.  If the  option  GLOBAL_EXPORT
              is  set,  this  implies  the option -g, unless +g is also
              explicitly given; in other words  the  parameter  is  not
              made  local  to the enclosing function.  This is for com-
              patibility with previous versions of zsh.

declare
       Same as typeset.

float [ {+|-}Hghlprtux ] [ {+|-}EFLRZ [ n ] ] [ name[=value] ... ]
       Equivalent  to  typeset  -E,  except  that options irrelevant to
       floating point numbers are not permitted.

integer [ {+|-}Hghlprtux ] [ {+|-}LRZi [ n ] ] [ name[=value] ... ]
       Equivalent to typeset -i,  except  that  options  irrelevant  to
       integers are not permitted.

local [ {+|-}AHUahlprtux ] [ {+|-}EFLRZi [ n ] ] [ name[=value] ... ]
       Same as typeset, except that the options -g, and -f are not per-
       mitted.   In  this  case the -x option does not force the use of
       -g, i.e. exported variables will be local to functions.

readonly
       Same as typeset -r.
