The setenv procedure sets the value of an environment variable in runenv.
setenv (name, value);
|name||Required. String that contains the name of the variable to set in runenv.|
|value||Required. String that contains the value of the specified variable.|
Because setenv is a procedure, no return value is set.
setenv ("SHELL", "/bin/sh");
In this example, the SHELL environment variable that is stored in runenv is set to /bin/sh.
