1.0 SUMMARY
LINK is the linking loader for the DECSYSTEM-20. LINK version 6.0 is
a development release designed to provide new features, enhancements
to existing features, internal changes, and support for Fortran-20
version 10. It contains long symbol support, several new REL blocks,
and improved handling of extended programs.
LINK version 6.0 supercedes all previous versions. It runs under
TOPS-20 versions 4.1(KS), 5.1, 6.0, and 6.1. Note TOPS-20 5.1 should
include an addition to the splice fork code. This is edit 3086 and
was shipped on Autopatch tape 8.
Microcode version 326 (or later) should be installed inorder to use
extended addressing
LINK is documented in the LINK Reference Manual. This manual is
available as part of volume 5 of the TOPS-20 Notebooks or separately
as order number AA-41830-TM.

2.0 EXTERNAL CHANGES
2.1 Changes To LINK
The following sections contain summaries of all important visible
changes that have been made to LINK since version 5.1(2030). Refer to
the section on internal changes for more information on specific
edits.
1. Increased reliability of extended addressing support. All
known problems with 30-bit addressing and multisection
programs have been fixed in this version.
2. Part of a program may occupy both section zero and other
sections. This removes a restriction on the previous
version.
3. Better error messages. The following new messages have been
added:
Suffix Lev Sev Standard Message Text
------ --- --- ---------------------
CBO 31 31 Cannot build overlays outside section zero
CCE 8 8 Character Constant not word aligned in call to routine
[routine] called from module [module] at location [address]
CCS 31 31 Cannot create section [octal]
{Detected in module [symbol] from file [file]}
CMP 31 28 Common [symbol] declared in multiple psects

{JSYS error text}
LINK.DOC -- Changes from LINK 5.1(2030) to LINK 6.0 (2364) Page 4
The following LINK error messages have been changed to
incorporate TOPS20 standard system error messages:
Suffix Lev Sev Standard Message Text
------ --- --- ---------------------
CLD 31 28 Cannot load DDT

{JSYS error text}
OTP 31 31 Error outputting area TP {Status [octal]} for file [file]
{JSYS error text}
4. Support of symbols up to 72 characters long and case
differentiation in symbols. This includes .REL block
support, entry and display at command level, but no debugger
support.
5. Improvements to program data vectors including static memory
maps and symbol vectors.
LINK.DOC -- Changes from LINK 5.1(2030) to LINK 6.0 (2364) Page 5
6. Multi-section FORTRAN common blocks.
7. FORTRAN extended addressing support.
8. New switches:
/NOJOBDAT
Prevents LINK from building a JOBDAT or vestigial JOBDAT area.
/PSCOMMON:psect:common
Cause the FORTRAN common having the name "common"
to be loaded into the specified psect. If "common" is omitted
the "blank common" is assumed. This switch must precede any
attempt to load the specified common and must also precede use
of the /COMMON switch in declaring the size of the common.
/REDIRECT:lpsect:hpsect
Causes LINK to load low segment code into the psect "lpsect"
and high segment code into the psect "hpsect". Either
"lpsect" or "hpsect" may be omitted, and the second colon is
optional if "highpsect" is omitted.
9. Paging of argument typechecking data so that larger FORTRAN
77 programs may be loaded.
10. Long PSECT Names - LINK now supports long psect names with
the same restrictions that apply to long symbol names. This
feature is supported for switches which require a PSECT name
as an argument and with type 1050 REL blocks.
11. Map File - This map file format now accommodates long symbols
and is therefore slightly different from the format produced
by LINK version 5.1.
2.2 Problems For Which No Solution Is Currently Planned.
1. If code or data that contains fixups (external, Polish,
inter-psect references, etc.) is overwritten at load time,
LINK can get an illegal memory reference or go into a loop.
This can happen if psects overlap, or if LOC or RELOC
statements are used incorrectly in a MACRO program. This is
a restriction.
2. Generation of a symbol file via /SYFILE: requires that
symbols be loaded with the program. This is a restriction.

3.0 INSTALLATION INSTRUCTIONS
To install LINK version 6 on your system, copy the files LINK.EXE and
OVRLAY.REL from the distribution tape to SYS:, and then copy the file
LINK.HLP from the distribution tape to HLP:. This can be done by
mounting the tape labelled Distribution Tape on MTA0:, then typing the
following commands:
R DUMPER
TAPE MTA0:
REWIND
DENSITY 1600-BPI
SKIP (to the appropriate save set)
RESTORE DSK*:<*>LINK.EXE (TO) SYS:*.*.-1, -
DSK*:<*>OVRLAY.REL (TO) SYS:*.*.-1, -
DSK*:<*>LINK.HLP (TO) HLP:*.*.-1
REWIND
To rebuild LINK from sources, mount the tape labelled Distribution
Tape on MTA0:, then type the following commands:
R DUMPER
TAPE MTA0:
REWIND
DENSITY 1600-BPI
SKIP (to the appropriate save set)
RESTORE DSK*:<*>*.*.* (TO) <self>*.*.*
REWIND
CTRL/C
!At this point, you should TYPE LINK.CTL to see what it does.
SUBMIT LINK.CTL/TIME/RESTART
The batch control file LINK.CTL contains the procedures necessary to
rebuild LINK and OVRLAY from sources. It may have to be modified
slightly to run at your installation, so you should type it to see
what it does before typing the SUBMIT command above.
4.0 INTERNAL CHANGES
2200 Expand the address field in the fixup blocks built by SY.CHP
to 30 bits. Make FXSPTR a static array, and make section zero
low segment code use the extended addressing code. Keep the
LS area chain seperate from the LC area chains. Fix type 2
block fixups (other than right half) in non-zero sections.
Routines: LNKPAR, LNKLOW, LNKCOR, LNKLOD, LNKNEW, LNKOLD
2201 Use the correct deferred fixup for the fullword replacement
store operator in the type 11 polish block.
Routine: LNKOLD
LINK.DOC -- Changes from LINK 5.1(2030) to LINK 6.0 (2364) Page 7
2202 Change the calling convention for the xx.IN and xx.OUT routines
to use T1 and T2 as 30 bit addresses for the lower and upper
bounds, instead of T1 as the lower,,upper bounds as 18 bit
addresses. Remove the FTFRK2 conditional, as it is always on
for TOPS-20. Remove the low segment global NONZER, and all
references to it. Use the xx.IN and xx.OUT routines instead of
bare PMAPs when possible, since these routines know about fixups
and about section creation. Remove code from LH.DMP, since it
does not need to create sections (they will be created by LC.IN).
Use the TOPS-10 code for initialization for reading the LS area
for the symbol table, since it is simpler and costs at most one
extra PMAP. Add the LNKCCS cannot create section message, and
the LNKMMF Memory Manager Failure message. Remove some error
messages which can no longer occur.
Routines: LNKD20, LNKT20, LNKPAR, LNKLOW, LNKCOR, LNKERR, LNKFIO,
LNKLOD, LNKMAP, LNKOLD, LNKOV1, LNKWLD, LNKXIT

2204 Don't lose the section number when doing type 10 fixups in
non-zero sections.

section addresses. Affects the type 1, 20, 21, 1004, and the
T.1010-T.1034 blocks.
Routines: LNKNEW, LNKOLD, LNKWLD

for calls to TRYSYM.
Routines: LNKPAR, LNKLOW

just been unmapped (performance improvement).
Routines: LNKCOR, LNKLOD, LNKMAP, LNKOLD
2216 Add or fix long symbol support in TRYSYM, INSRT, LS.ADD,

correctly. Remove the LNKESN message.
Routines: LNKERR, LNKHSH, LNKLOD, LNKLOG, LNKMAP, LNKOLD, LNKWLD

Routine: LNKLOD
2220 More long symbol support. Add support for typing long symbols
in commands. Fix all switch processors to handle them. Make

psect names.
Routines: LNKPAR, LNKLOW, LNKLOD, LNKMAP, LNKOLD, LNKSCN,

Routine: LNKLOD
2225 Fix /PVDATA:VERSION:SYMBOL, broken by edit 2220.
Routine: LNKWLD
2226 Fix up support code for long /INCLUDE and /EXCLUDE so long
blocks get returned properly. Also, don't do a long compare
for the title in a type 6 block, since it is always short.

psect the /COMMON switch should place a common block in.
Routines: LNKPAR, LNKLOW, LNKLOD, LNKWLD

Routine: LNKXIT
2242 Create sections for psects, even if nothing has been
stored in them.
Routines: LNKCOR, LNKLOD
2243 Fix off-by-one bugs in edit 2242, add code which makes sure

globals. Make the fixup block have the global
pointer in the second word and the local pointer
in the third word. Redo the polish block code
to store the section number of the LS area in the
op code, similar to what edit 2203 did for memory
fixups.
