+I've been fooling around with APL\11 that we got from Purdue.  Here are
+some comments:
+
+First, you should look at the READ_ME file.  This has some important
+notes about editing the source before you compile.  I've only compiled
+it on the VAX, so I had to add the DVMUNIX flag.  The directory
+/manual  has the nroff source to make a manual.  It also has a
+READ_ME with some useful info.
+
+If you are using an APL terminal, you should probably set the erase
+character to something other than backspace (for example, escape).  You
+do this with <stty erase ...>.  You should probably turn off echoing
+of the control characters with a <stty -ctlecho> command.  This lets
+you do real overstriking.  You should probably also change the kill
+character to something other than the ampersand.
+
+Don't forget to invoke apl with the -m option when you use it.
+
+To make the editor work you must edit line 33 of ai.c so it can
+find the editor on your own disk, not /bin/xed etc.
+
+There are some bugs.  For example, ( iota 0 )/ iota 0    gives an
+INTEGER DIVIDE error.  This is really strange, considering that the
+slash there is compression, NOT division!  Also, scans STILL work
+backwards.  Try  divide \ 1 2 3  and compare with regular APL.
+
+There are several workspace distributed with this APL.  They are
+in the directory /lib  , which also has a READ_ME file.
