This file contains last minute information and warnings relevant
to the ALGOL 10B/1.2(310) release. Critical bug fixes discovered
since the software and the DOC file were submitted for distribution
are listed here. In addition, this file also contains bugs fixes to
other products that directly affect the usage/building of this version
of ALGOL. This file serves as additional information to ALGOL.DOC,
which should be referenced for full information concerning this
release.
[SYMPTOM]
The ALGOL OTS and debugger (ALG310) will not function properly
when protected execute-only on a KI10. This is due to a deficiency in
the KI processor, such that when an XCT instruction is executed from a
concealed area, and the instruction being executed is in a public
area, a memory protection violation is produced. This occurs even if
the public area is not actually entered, and regardless of whether or
not the XCT is followed by a PORTAL. Refer to the
DECsystem-10/DECSYSTEM-20 Processor Reference Manual, AA-H391A-TK,
Section 2.9, page 2-63, footnote 18.
[CURE]
In all cases where the OTS and ALGDDT would do such a XCT
instruction, move the XCT and an appropriate JRST to the high seg into
the low seg (either on the stack, on in the program data base), and
jump to do the XCT completely in the low seg. The JRST to the high
seg will re-enter the concealed area at an appropriate PORTAL. The
following code is provided only as a workaround for this KI hardware
deficiency, and will not appear in any version of the ALGOL product.
It is applicable to edit level 310, and has been given minimal testing
on a KI10 while protected execute-only (protection <666>).

[SYMPTOM]
If a program contains a macro with the same name as the tag for
the starting address, no start block is generated. When assembling
one of the ALGOL source modules (using MACRO with edit 1155 installed)
that uses this code sequence, a bad .REL file will be produced which
will cause LINK to Ill Mem Ref. This occurs because the MACRO END
Page 5
psuedo-op code incorrectly determines that the starting address is
located in other than the current Psect, causing an incorrect
inter-Psect Polish block to be generated instead of a start address.
[CURE]
Only use the right halfword of the current Psect for comparisons.
This patch is only applicable if edit 1155 has been installed to field
image MACRO 53A(1152).

[SYMPTOM]
If FORTRAN subroutines are loaded with an ALGOL main program,
FORLIB (version 6 only) code will be loaded into the high segment.
This happens because LINK does not check where the code should go if
Page 6
loading FORLIB unless the main program is FORTRAN.
[CURE]
Test to see whether there is a high segment. If there is not,
and the /OTSEGMENT:NONSHAR has not been given, load FORLIB in the low
segment. Note that the tag offsets (which apply to field image LINK
4A(1220)) are slightly different if edit 1225 has been installed.

[SYMPTOM]
LINK produces %LNKSFU symbol table errors when loading an ALGOL
program in a small amount of memory or with a small /MAXCORE setting.
This happens because if LINK has insufficient memory to keep all
tables in memory, the ALGOL symbols are the first thing to be paged
out to an overflow file. When this happens, LINK removes the entire
ALGOL symbols area from memory. Later, when the ALGOL symbols area is
to be expanded, LINK does not check to see if there are symbols in
memory, and attempts to move the memory resident area with the
exchange pages PAGE. UUO. Since there are no ALGOL symbols to
exchange, a page from the next area higher, the local symbols area, is
exchanged with a page of zeros.
[CURE]
Page 11
Do not exchange pages if the area being expanded has been
entirely paged to disk.
