load f1 f2 ...  loads and executes files f1.m, f2.m, etc. which should be
	files of M commands or function definitions.  If a file name contains
	non-alphanumeric characters, enclose it in "quotes".  M looks for the
	specified files in the current directory, or, if not found, looks in
	the M library (/opt/m/lib/).  If no files are specified, load tries to
	load "save.m".  Input can be redirected from a file also, e.g. load <file.

	Use of the load command within functions is not recommended because
	the load does not take effect until after the function exits and M
	starts to read more input.
