37.4. $homeDirectory

If the operating system defines a notion of “home file directory”, $homeDirectory returns its name; consult the appropriate system-specific MAINSAIL user's guide for details. If an error occurs, the null STRING is returned, msg is set to a STRING describing the error, and if errorOK is not set in ctrlBits, an error message is issued. errorOK is the only valid bit in ctrlBits.
