---- Atari ST port of I-APL ---------------------------------------------------
Welcome to I-APL. The files on this disk are as follows:
IAPL.TOS The I-APL interpreter.
*.IWS I-APL workspaces to load.
*.IMD *.IXX Additional modules for the IAPL.TOS program.
See the manual for an explanation of these files.
---- Copyrights ---------------------------------------------------------------
The I-APL interpreter is Copyright (c) 1987,1988,1989 I-APL Ltd.
The code specific to the ST port, including the modules, is
Copyright (c) 1992 J.S.Peters.
---- Reading ------------------------------------------------------------------
In addition to the I-APL manual, there are two other books of particular
interest to I-APL users. Both are available from I-APL Ltd:
'An APL tutorial' by Linda Alvord and Norman Thomson. This tutorial takes the
reader through the basic concepts of APL, with many examples and applications.
'An Encyclopedia of APL' by Garry Helzer. This is a language reference manual,
written for I-APL. It describes each APL command and operator in detail, with
many examples and discussions of important points.
---- Bugs ---------------------------------------------------------------------
There is one known bug in the interpreter. If you accidently swap round the
left and right arguments for 'drop', IAPL.TOS may crash. The bug comes up
if a long (say, 1000-element) vector is passed as the left argument for 'drop'.
Normally the longest vector you would want to pass on the left is a 7-element
one, so this bug is easy to avoid once it is recognised.
