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



DESCRIPTION
     The shell can access environment variables using all 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/OS.
     Consult the Domain/OS documentation for additional information.

NOTE
     The shell creates environment variables in uppercase only.  (Environment
     variables are case sensitive in Domain/OS; the shell allows only
     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 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.)
