help name
(help)


command. Prints information from the reference manual about the primitive procedure named by the input. With no input, lists all the primitives about which help is available. If there is an environment variable ALOGOHELP, then its value is taken as the directory in which to look for help files, instead of the default help directory.

Exceptionally, the HELP command can be used without its default input and without parentheses provided that nothing follows it on the instruction line.

Example: 

help [word]

will print: 

Help Contents / Data Structure Primitives / Constructors / Word

Word word1 word2
(Word word1 word2 word3 ...)

outputs a word formed by concatenating its inputs.

Examples:
	
	show word "hal "lo	;hallo
	show (word [wor ld])	;wor ld
	show (word {a b c})	;{a b c}
	show word "12 "34		;1234
