Date:	4:51pm  Tuesday, 12 October 1982
Source:	PI:EXPLODE-COMPRESS.RED
Module: IO in kernel
Remarks: The numbers 0..9 no longer work the same as !0..!9

Bug:	In open-coded arithmetic/vector access.
Fix:	Added (USESDEST USESDEST) clause to ASSOCPAT
By:	Eric
Date:	11:10am  Monday, 11 October 1982
Source:	P20C:DEC20-COMP.RED and PVC:VAX-COMP.RED; P68C:M68K-COMP.RED should
	also be changed.
Module:	DEC20-COMP and VAX-COMP
Remarks:

Bug:	Catch no longer needed in Read, due to change in EOF handling
Fix:	Removed CATCH($READ$, ChannelRead IN*) from READ, similarly for
	COMPRESS and IMPLODE

Bug:	There is no EXPR for reading files
Fix:	Change DSKIN from a FEXPR to a one argument EXPR
By:	Eric
Date:	12:14pm  Tuesday, 5 October 1982
Source:	PI:DSKIN.RED
Module:	IO in kernel
Remarks: This change is incompatible for those using DSKIN with multiple
	arguments.  These uses will have to change to multiple DSKINs.

Feature: The printing functions use the variables PRINLEVEL and PRINLENGTH,
	as described in the Common Lisp Manual.

Bug:	BIGNUM quotient, re-evaluation errors
Fix:	Improved BIGNUM and BIGFACE installed
By:	M. L. Griss, for A. C. Norman
Date:	4 October 1982.
Source:	PU:BIGFACE.RED, PU:BIGBIG.RED
Module:	BIGNUM
Remarks:	Some errors still remain, in BLDIFF, etc. and
        minor typo's fixed.

Bug:	Scantable in POLY was inherited from CURRENTSCANTABLE!*
	not "nice" under PSL
Fix:	Added an ALGSCANTABLE!*, similar to RLISP table
By:	Martin
Date:	3:41pm  Tuesday, 28 September 1982
Source: PU:POLY.RED
Module: POLY
Remarks:

Bug:	PRINTX in DEBUG didn't handle circular vectors.
Fix:	Now it does.
By:	Eric
Date:	5:44pm  Friday, 24 September 1982
Source:	PU:DEBUG.RED
Module:	DEBUG
Remarks: Also made DEBUG use CODE-NUMBER-OF-ARGUMENTS to find out the
	# of arguments to a compiled function.

Feature: The printing function for code pointers prints the number of
	arguments expected, in the format #<Code 3 284313>, where 3
	is the # of arguments and 284313 is the address.  The address
	part is now printed in the "preferred" radix of the machine,
	defined by the WConst CompressedBinaryRadix, which is 8 on the
	Dec-20 and Cray, and 16 on the Vax, 68000, and 360.

Source:	PI:PRINTERS.RED and PXX:GLOBAL-DATA.RED (for constant definition)
Module:	IO in kernel
Remarks:

Bug:	No way to find out how many arguments a compiled function gets.
Fix:	Put a header above the entry point with the # of arguments,
	accessed by the function CODE-NUMBER-OF-ARGUMENTS, which expects
	a code pointer as its argument and returns the number of arguments
	the code pointer expects, or NIL.
By:	Eric

Source:	PC:PASS-1-LAP.SL (to add header word), PC:DATA-MACHINE.RED (to define
	access macro), PI:PUTD-GETD.RED (to define callable entry point).
Module:	PASS-1-LAP, SYSLISP, PROP in kernel
Remarks: Only functions compiled since this change have the header word;
	old FASL files will have to be recompiled to make use of this
	feature.

Bug:	IDs (symbols) are not garbage collected.
Fix:	Allocate symbols as a free list linked through the name cell
