LIBEVAL	Command
Type:
Description:	Evaluate Library Function Command: Evaluates unnamed library functions.
	WARNING: Use extreme care when executing this function. Using LIBEVAL
	with random addresses will almost always cause a memory loss. Do not use this
	function unless you know what you are doing.
	#nfunction is of the form lllfffh, where lll is the library number, and fff the function number.
Access:	…µLIBEVAL

Input/Output:

		Level 1/Argument 1	Level 1/Item 1
		#nfunction	→

LIBS	Command
Type:
Description:	Libraries Command: Lists the title, number, and port of each library attached to the current
	directory. The title of a library often takes the form LIBRARY NAME : Description. A library
	without a title is displayed as " ".
