======Synopsis:======
__setenv__ <var-name> <value> \\
__setenv__ -<var-name>

======Description:======
In the first usage, __SETENV__ sets the environment variable <var-name>
to <value>.  This new value will be visible to all of the processes that
you [[exec command|EXEC]].  In the second usage, the environment
variable <var-name> is unset (deleted), and is no longer visible to
[[exec command|EXEC]] processes.

Some systems (like Solaris) make changing and deleting environment 
variables painful.  Upon these kinds of systems, EPIC may output a 
warning advising you that setting an environment variable will result
in a memory leak which is unavoidable.  These systems also do not 
have an easy way to unset environment variables.  If you try, you will 
get a warning telling you this.
