^DEAR <PASCAL ^USER:
.P
^ENCLOSED IS A COPY OF THE FIRST UPDATE TO THE <BSM ^PASCAL COMPILER
AS WELL AS A COPY OF THE ^SWEDISH ^PASCAL COMPILER. ^THE UPDATED
<BSM ^PASCAL COMPILER INCLUDES THE BUG FIXES REPORTED IN THE 1.1
ISSUE OF THE <PASCAL <SIG NEWSLETTER AS WELL AS THE ^PASCAL VERSION
OF <PASS2 OF THE COMPILER. ^SINCE MOST OF THE BUG FIXES ARE IN
<PASS2 OF THE <BSM COMPILER, THE ^PASCAL VERSION OF <PASS2 WILL
SUPERCEED THE <BSM VERSION AS OF ^SEPTEMBER 12, 1977.
^THE ^SWEDISH ^PASCAL COMPILER WAS RECEIVED FROM ^THOMAS ^PORTER
AND ^WAYNE ^RASBAND OF <NIH WHO HAD EARLIER OBTAINED IT FROM
^DU^PONT. ^IT WAS DEVELOPED FROM ^URS ^AMMANN'S <PASREF COMPILER
FOR THE <DEC-10 WHICH WAS FIRST MODIFIED BY ^W. DE^VRIES AND
^C. ^BRON TO GENERATE <PDP-11 CODE AND AGAIN MODIFIED BY ^SEVED
^TORSTENDAHL TO ACTUALLY COMPILE ^PASCAL PROGRAMS ON AN <RSX-11M
SYSTEM. ^IT IS A ONE PASS COMPILER WHICH GENERATES OBJECT MODULES
WHICH ARE OVERLAYABLE AND CAN REFERENCE SEPARATLY COMPILED PROCEDURES
AS WELL AS <FORTRAN OR <MACRO SUBROUTINES.
^THE COMPILER REQUIRES A TASK SPACE OF 173000 OCTAL BYTES AND AT THAT
IT IS NOT LARGE ENOUGH COMPILE ITSELF. ^CHANGES TO THE COMPILER ITSELF
WILL THEREFORE REQUIRE A <DEC-10. ^WE HAVE MADE SOME MINOR CHANGES
TO THE LIBRARY ROUTINES SUPPLIED BY ^TORSTENDAHL TO ALLOW THE COMPILER
TO BE USED ON <RSX-11D OR <IAS AS WELL AS ON <RSX-11M.
.P
^THIS RELEASE TAPE CONSISTS OF THE FOLLOWING <UIC'\S:
.LIST 2
.LE;[70,1] - ^PASCAL USER ROUTINES AND DOCUMENTATION FILES.
.LE;[70,2] - <BSM MACROS, RUN-TIME SYSTEM AND <PASLIB.
.LE;[70,4] - <BSM SOURCES, OBJECTS, AND BUILD FILES FOR <PASS1.
.LE;[70,7] - <RSX-11M REPLACEMENT FILES FOR <BSM LIBRARY, COMPILER,
AND RUN-TIME SYSTEM.
.LE;[70,11] - ^PASCAL VERSION OF <PASS2... 
.LE;[70,16] - ^SWEDISH ^PASCAL COMPILER SOURCES, USER MANUAL, GENERATION
MANUAL, AND UTILITY ROUTINES.
.ELS

^THE FOLLOWING INSTRUCTIONS ARE FOR BUILDING ^PASCAL ON <RSX-11D,M SYSTEMS.
^FOR OTHER SYSTEMS SUCH AS <RSTS, ADDITIONAL INSTRUCTIONS WILL APPEAR IN 
THE <PASCAL <SIG NEWSLETTER.
^IF POSSIBLE INITIALIZE <UFD'\S [70,1], [70,2], [70,3], [70,4], [70,7],
[70,11], AND [70,16] ON YOUR SYSTEM DISK AND USE <FLX WITH THE
FOLLOWING COMMAND LINE TO COPY THE FILES FROM TAPE TO DISK:
.BLANK 1
^^FLX SY:/RS/UI=MT0:[*,*]*.*/DO\\
.BLANK 1
^AFTER THE FILES HAVE BEEN TRANSFERED TO THE SYSTEM DISK, A <RSX-11D
^PASCAL COMPILER CAN BE BUILT IMMEDIATELY BY:
.LIST 2
.LE;^LOG ON TO [70,4] AND ^^TKB @TKBPASCAL\\.
.LE;^LOG ON TO [70,11] AND ^^TKB @PASS2\\.
.LE;^LOG ON TO [1,1] AND INSTALL [70,4]<PASCAL AND [70,11]<PASS2.
.ELS
^FOR <RSX-11M SYSTEMS, THE FILES CONTAINED UNDER [70,7] MUST REPLACE
THE SAME FILE UNDER [70,2].
<[70,2]PASLIB.MAC AND <[70,11]PASEXTLIB.MAC MUST BE REASSEMBLED UNDER
<RSX-11M AFTER COMMENTING OUT THE SYSTEM SELECTOR SWITCH. (<RSX11D)
<PLIBF.MAC MUST ALSO BE ASSEMBLED AND REPLACED IN <BSMLIB.OLB.
^THE COMPILER MAY THEN BE BUILT WITH THE COMMAND FILES FROM [70,7]
WHICH YOU MAY WANT TO MODIFY TO INCLUDE A REFERENCE TO YOUR SYSTEM
LIBRARY. ^AFTER THE COMPILER HAS BEEN TASK BUILT AND INSTALLED, IT 
WILL FUNCTION IDENTICALLY TO THE <RSX-11D COMPILER.
.P
^THE ^SWEDISH ^PASCAL COMPILER MAY BE BUILT BY TRANSFERRING ALL OF THE
FILES UNDER [70,16] ON THE RELEASE TAPE TO ANY ACCOUNT.
^THE FOLLOWING COMMANDS WILL THEN BUILD THE COMPILER AND INSTALL
THE RUN-TIME LIBRARY IN <SYSLIB.

^THE TASK IMAGE MAY BE MOVED TO [1,54] OR [11,1] IF DESIRED BEFORE
INSTALLING IT.
^THE SOURCES FOR
THE COMPILER AND THE RUN-TIME SYSTEM HAVE BEEN PACKED INTO TWO FILES
(<SRCFIL.PAC AND <PASLIB.PAC) TO REDUCE THE NUMBER OF FILES ON THE TAPE.
^TASK BUILD <UNPACK, <LISTPACK, <PACK, AND <PACKLIB AND READ THE SOURCE
FILES TO DETERMINE HOW TO UNPACK AND USE THOSE FILES.
.P
^THE <USER.MAN FILE CONTAINS AN ADDENDUM TO ^JENSEN AND ^WIRTH'S
"^PASCAL ^USER ^MANUAL AND ^REPORT" DESCRIBING HOW TO USE THIS COMPILER
AND WHAT ARE ITS SPECIAL CHARACTERISTICS.  ^THOMAS ^PORTER REPORTED
THAT HE HAD SOME DIFFICULTY USING THE COMPILER UNDER <RSX-11M SINCE
<MCR WOULD GRAB UNSOLICITED INPUT.  ^UNDER <RSX-11M ^V3, USERS CAN USE
THE <ATTACH AND <DETACH PROCEDURES TO PREVENT THAT PROBLEM.
.P
^AGAIN ^I WOULD LIKE TO SOLICITE COMMENTS ON ^PASCAL COMPILERS AND
SPECIFICALLY HOW THESE COMPILERS PERFORM ON YOUR SYSTEMS.
.P
^THANK YOU FOR YOUR INTEREST.
