EXPORT -- Change a Shell variable into an Environment variable.
usage:  EXPORT var_name...


FORMAT

  EXPORT var_name...


  The  Shell  can access enviroment variables using all of the standard variable
  commands and operators.  The EXPORT command adds  the  capability  of  turning
  regular Shell variables into environment variables.

  Environment  variables  are variables that programs can access or set and that
  are  used  to  store  global  state  information.    Several   are   generated
  automatically  when you create a process; they can be displayed using the LVAR
  (LIST_VARIABLES) command.  For example:

      $ lvar
      environment NODETYPE = DN400
      environment TZ = EST5EDT
      environment PATH = :~com:/usr/ucb:/bin:/com:/usr/bin
      environment TERM = apollo_15P
      environment HOME = //node_8e4/joseph
      environment USER = joseph
      environment LOGNAME = joseph
      environment PROJECT = none
      environment ORGANIZATION = r_d
      environment NODEID = 8E4
      $

  Environment variables are of special interest to users of DOMAIN/IX.   Consult
  the DOMAIN/IX documentation for additional information.

  NOTE: The Shell creates environment variables in UPPERCASE only.  (Environment
        variables are  case  sensitive  in  DOMAIN/IX;  the  Shell  only  allows
        uppercase  ones  to  avoid  collisions between environment variables and
        Shell variables.)


ARGUMENTS

  var_name
  (required)          Specify  the  Shell  variable  to  be  changed   into   an
                     environment variable.  It doesn't matter whether or not the
                     name is typed  in  uppercase;  the  Shell  converts  it  to
                     uppercase  automatically.    Multiple  variable  names  are
                     permitted, separated by blanks.  If the specified  variable
                     does not exist, EXPORT creates it.


EXAMPLES

  $ eon
  $ current_dir := "//panacea/joe"
  $ lvar
  string current_dir = //panacea/joe       (Shell variable created.)
  environment USER = joe
  environment LOGNAME = joe
  environment PROJECT = none
  environment ORGANIZATION = r_d
  environment NODEID = D5B
  environment PATH = :~com:/usr/ucb:/bin:/com:/usr/bin
  environment TERM = apollo_19L
  environment NODETYPE = DN300
  environment TZ = EST5EDT
  environment HOME = //panacea/joe
  $ export current_dir
  $ lvar
  environment USER = joe
  environment LOGNAME = joe
  environment PROJECT = none
  environment ORGANIZATION = r_d
  environment NODEID = D5B
  environment PATH = :~com:/usr/ucb:/bin:/com:/usr/bin
  environment TERM = apollo_19L
  environment NODETYPE = DN300
  environment TZ = EST5EDT
  environment HOME = //panacea/joe
  environment CURRENT_DIR = //panacea/joe  (Environment variable created.)
