pps on PURPG

[REM at MIT-MC (Robert Elton Maas)]

See REM;BUG1 >
If BAR called interpreted, ;FOO UNDEFINED FUNCTION OBJECT,
but the combination of (DECLARE (ARRAY* ...)) putting a #DEAD-ARRAY around
and COMPLR defaulting to Opencodearrays while not a bug sure was confusing
for awhile.  I guess in the future I'll compile with -O the first time
just to be sure unexpected differences between interp and compiled 
environment don't cause PURPG -- Compiling BUG1 > with -O gives
;FOO UNDEFINED FUNCTIN OBJECT IN UUO CALL instead of PURPG.
(Should default switch really be O ???  After all default is *RSET and
(NOUUO T) to make debugging easier.)
