SETENV/SET User Commands
set VARIABLE = VALUE
Each process has its own Environment. This command displays the variables
that may be defined in the current Environment.
If VARIABLE is specified its value will be displayed. If VALUE is given
then the variable will be replaced.
Environment variables are case-sensitive and are inherited from a parent
An Env/ Registry Key may be used to pre-initialize a variable in the
Environment. This would insure that it is always defined.
