Routine Name:
setenv
Description:
Set value of operating system environmental variable.
Usage:
setenv environment-variable [new-value...]
Example:
genesis > setenv SIMPATH . ~/genesis/Scripts/neurokit
SIMPATH=. ~/genesis/Scripts/neurokit
[also see the GENESIS default .simrc file]
Notes:
This is a GENESIS implementation of the operating system
command setenv, which lets you set the value of a particular
operating system environmental variable. Unlike its
operating-system counterpart, setenv from within GENESIS
requires that you supply a variable name (outside of GENESIS,
setenv with no arguments displays the list of all your
environmental variables).
Unlike its operating system counterpart, setenv from within
GENESIS displays the change that you make (outside of
GENESIS,
setenv just returns you to the prompt with no
acknowledgement).
The setenv routine is used most commonly from within GENESIS
to define the DISPLAY and SIMPATH environment variables.
DISPLAY determines the X11 host on which the display is made
and SIMPATH lists the path which the simulator will search
through for script files (cf. where).
