Store frequently used options in the ILINK environment variable. This method is useful if you find yourself repeating the same command-line options every time you link. You cannot specify file names in the environment variable, only linker options.
The ILINK environment variable can be set either from the command line, in a command (.CMD) file, or in the System Properties. If it is set on the command line or by running a command file, the options will only be in effect for the current session (until you reboot your computer). If it is set in the System Properties, the options are set when you boot your computer, and are in effect every time you use the linker unless you override them using a .CMD file or by specifying options on the command line.
