APL+WIN V3.6 Bugs
-----------------

1.  Missing Error Message

''+{enclose}'1 2'({enclose}{iota}4)

should be a domain error, but isn't

The same expression should be equivalent to

''+0{rho}{enclose}'1 2'({enclose}{iota}4)

due to scalar extension, but isn't (the prototype is much richer).


2.  Incorrect Prototype

(0{rho}{enclose} 0 (0 0)) + 0{rho}{enclose} (0 0) 0

should return

0{rho}{enclose} (0 0) (0 0)

but instead returns

0{rho}{enclose} (0 0) 0


3.  Incorrect Prototype

2 +/{enclose} 1 2

yields an empty character vector!


4.  Error instead of result

'abc'[0.5] 1 2 3

should yield a heterogeneous array, but instead signals a DOMAIN ERROR


5.  Incorrect Display

'abc' tclf 'ef'

displays as

 abc
      ef

instead of

 abc    ef

followed by a blank row


6.  Incorrect Display

0{rho}1 2

displays an empty line

0{rho}{enclose}1 2

displays without skipping a line


7.
