>Summary: some array references translated incorrectly

Initial Comment:
(A) With   array (u,integer,5); hh():=block(u[2]:333, print(u[2])); compile(hh) leads to error message but compile('hh) works.

(B) With   pp(n):=block(a:0, print(n+a));  compile(pp) gives "Warning-> a is an undefined global variable." but compile('pp) does not.

Message:
Changed title to reflect bug identified by (A). Looks like the problem is
in the code generated for arrays declared with a specific type.

Message:
Item (b) is not a bug; the error message is correct.

The error message caused by (a) is due to incorrect translation of array
references when a type is specified for the array (i.e. array(u, integer,
5) instead of array(u, 5)). I'm looking into it.

Note in either case that compile('foo) causes no warning or error because,
in fact, nothing is translated; compile doesn't understand 'foo, only foo.
