NAME
	apl - APL interpreter
SYNPOSIS
	apl
DESCRIPTION

This is a preliminary version of APL which has been installed by 
popular demmand. ****use at your own risk****. The interperetor started
life at bell labs, then went to yale and finally came to Purdue via
Chicago.  We have only had it a couple of weeks and many changes will
be made in the near future.  So if something suddenly does not work
first check with "help apl/changes".

Function definition is not what you would expect.  Functions are loaded
from files.  The first line of the file is the function header, as you
would expect it but with no del.  The rest of the file is the lines
of the function.  Lines are numbered, but there's none of the
square bracket jazz.  If you say )READ FILE it will load the function
in that file.  If you say )EDIT FILE it will put you in the
unix editor to change that file. Upon exit, it will read the file in
as though by )READ.

All of the usual operators are available, including domino.

BUGS
	I don't know of too many, but mail any trouble reports to reeves.
	Interpreter occasionally blows up.
	Character comparisons don't work (but try concatenating
	 a character vector to a numeric vector and vice versa.)
	Many mixed functions take less general arguments than
	you might expect.  Then again any integer origin is allowed.
