JCL support as alternative to system menu.

In our continuing effort to support languages other than LISP on the CADDR,
we have developed an OS/360-compatible JCL.  This can be used as an
alternative to the standard system menu.  Type System J to get to a JCL
interactive read-execute-diagnose loop window.  [Note that for 360
compatibility, all input lines are truncated to 80 characters.]  This
window also maintains a mouse-sensitive display of critical job parameters
such as dataset allocation, core allocation, channels, etc.  When a JCL
syntax error is detected or your job ABENDs, the window-oriented JCL
debugger is entered.  The JCL debugger displays appropriate OS/360 error
messages (such as IEC703, "disk error") and allows you to dequeue your job.

The garbage collector now works.  In addition a new, experimental garbage
collection algorithm has been installed.  With SI:

DSK-GC-QLX-BITS set to 17,
(NOT the default) the old garbage collection algorithm remains in force; when
virtual storage is filled, the machine cold boots itself.  With SI:

DSK-GC-
QLX-BITS set to 23, the new garbage collector is enabled.  Unlike most garbage
collectors, the new gc starts its mark phase from the mind of the user, rather
than from the obarray.  This allows the garbage collection of significantly
more Qs.  As the garbage collector runs, it may ask you something like "Do you
remember what SI:RDTBL-TRANS does?", and if you can't give a reasonable answer
in thirty seconds, the symbol becomes a candidate for GCing.  The variable
SI:

GC-QLX-LUSER-TM governs how long the GC waits before timing out the user.

There has been some confusion concerning MAPCAR.
        (DEFUN MAPCAR (&FUNCTIONAL FCN &EVAL &REST LISTS)
                (PROG (V P LP)
                (SETQ P (LOCF V))
        L       (SETQ LP LISTS)
                (

START-FUNCTION-CALL FCN T (LENGTH LISTS) NIL)
        L1      (OR LP (GO L2))
                (AND (NULL (CAR LP)) (RETURN V))
                (

PUSH (CAAR LP))
                (RPLACA LP (CDAR LP))
                (SETQ LP (CDR LP))
                (GO L1)
        L2      (

FINISH-FUNCTION-CALL FCN T (LENGTH LISTS) NIL)
                (SETQ LP (

POP))
                (RPLACD P (SETQ P (NCONS LP)))
                (GO L)))
We hope this clears up the many questions we've had about it.
