Referencing environment variables within ModelSim

There are two ways to reference environment variables within ModelSim. Environment variables are allowed in a FILE variable being opened in VHDL. For example,

entity test is end;
use std.textio.all; 
architecture only of test is 
begin
	process
		FILE in_file : text is in "$ENV_VAR_NAME";
	begin
		wait;
	end process;
end; 

Environment variables may also be referenced from the ModelSim command line or in macros using the Tcl env array mechanism:

echo "$env(ENV_VAR_NAME)"
