H IN\ @ UFLIP LIBRARIES CONSIST OF THREE TYPES OF BLOCKS: INDEX BLOCKS,
RIB BLOCKS, AND DATA BLOCKS. THE LIBRARY BEGINS WITH
ONE OR MORE INDEX BLOCKS CONSISTING OF A SET OF TWO WORD ENTRIES, ONE
ENTRY FOR EACH FILE IN THE LIBRARY DENOTING ITS NAME, EXTENSION AND
LENGTH IN BLOCKS. THE INDEX IS FOLLOWED BY THE EXTENDED LOOKUP TABLE
(RIB) FOR THE FIRST FILE IN THE LIBRARY. THIS BLOCK IS THEN
FOLLOWED BY THE FIRST FILE. RIBS AND DATA THEN ALTERNATE THROUGGHOUT
THE LIBRARY AND ARE IN THE SAME ORDER AS THE ENTRIES IN THE INDEX.
TO ASSEMBLE, LOAD, AND SAVE THE REENTRANT UFLIP TYPE
LOAD @UFLIP
SSAVE UFLIP
WHEN UFLIP APPENDS TO A LIBRARY, IT USES THE UPDATE MODE.
THIS CAN BE A PROBLEM IF THE DISK IS NEARLY FULL AND THE LIBRARY
FILE BECOMES BADLY FRAGMENTED. THE PROBLEM IS THAT THE INDEX OF THE
LIBRARY FILE GETS UPDATED BEFORE THE APPEND IS ATTEMPTED AND IF THE ATTEMPT
FAILS THE INDEX AND THE LAST FEW BLOCKS OF THE LIBRARY ARE
MESSED UP. THIS CAN BE ALLEVIATED BY PREVENTING A SIMPLE APPEND, BUT
INSTEAD REQUIRING THE ENTIRE LIBRARY TO BE RECOPIED ON EACH APPEND.
THEN WHEN THE FRAGMENTATION PROBLEM OCCURS, A RESET WITHIN UFLIP
WILL NEGATE THE ENTIRE APPEND. OF COURSE IN THIS MODE UFLIP
RUNS CONSIDERABLY SLOWER, WHILE APPENDING, AND MORE DISK SPACE
IS TIED UP DURING THE APPEND IN THAT MULTIPLE COPIES EXIST.

^GENERAL
.SK 1
^THE PROGRAM ^^UFLIP\\ HAS ONE PRIMARY PURPOSE: TO PROVIDE ^^PDP\\-10
USERS WITH THE CAPABILITY OF COMBINING SEVERAL SMALL DISK FILES INTO
ONE LARGER FILE (LIBRARY) IN HIS OWN AREA WITH THE PROVISION FOR
SUBSEQUENT UPDATING AND EXTRACTION. ^THE REASONS FOR SUCH A CAPABILITY ARE:
1) TO ALLOW FOR A NUMBER OF FILES
TO BE STORED ON ^^DEC\\-TAPE, IN EXCESS OF THE NUMBER WHICH CAN BE
CONTAINED IN A ^^DEC\\-TAPE DIRECTORY, 2) TO REDUCE THE DISK BLOCK
OVERHEAD CAUSED BY FILES OCCUPYING AN INTEGRAL NUMBER OF DISK CLUSTERS,
AND 3) TO ALLOW USERS TO CATEGORIZE GROUPS OF FILES PERTAINING TO COMMON
TASKS OR SUBJECTS.
.SK 2
.ND -5
^FUNCTIONS
.SK 1
^ALL FILES AND LIBRARIES INVOLVED MUST RESIDE ON DISK TO BE MANIPULATED
BY ^^UFLIP\\. ^IT CAN BE USED TO CREATE LIBRARIES, TO ADD FILES TO
OR DELETE FILES FROM THEM, REPLACE (UPDATE)
COPIES OF FILES IN THEM, EXTRACT FILES FROM THEM, AND LIST THEIR
CONTENTS.

^CREATION:####^CREATING A LIBRARY CAUSES A NEW LIBRARY,
CONSISTING OF FILES IN THE USER'S DIRECTORY OR DIRECTORIES, WHICH
MATCH FILES IN THE LIST (SEE DESCRIPTION OF LIST BELOW), TO BE FORMED.
^THE LIBRARY FILE CREATED REPLACES ANY
PREVIOUS VERSION OF A FILE WITH THE SAME NAME IN THE USER'S
DIRECTORY.
.SK 1
.ND -5
^ADDITION:####^ADDING TO A LIBRARY CAUSES ALL FILES IN THE USER'S
DIRECTORY OR DIRECTORIES, WHICH MATCH ENTRIES IN THE LIST,
TO BE APPENDED TO THE LIBRARY FILE REGARDLESS OF THE PRIOR EXISTENCE
OF SUCH A FILE IN THE LIBRARY. ^SHOULD THERE BE NO LIBRARY IN EXISTANCE,
ADDITION WOULD REDUCE TO CREATION.
.SK 1
.ND -5
^DELETION:####^DELETING CAUSES ALL COPIES OF ALL
FILES IN A LIBRARY, WHICH MATCH
LIST ENTRIES, TO BE DELETED FROM THE LIBRARY.
.SK 1
.ND -5
^REPLACEMENT:#^REPLACING CAUSES ALL COPIES
OF ALL FILES IN A LIBRARY, WHICH MATCH ENTRIES IN THE
LIST, TO BE REPLACED BY FILES FROM THE USER'S DIRECTORY.
^IF REPLACEMENTS ARE NOT AVAILABLE FOR ALL FILES TO BE REPLACED, THE
OLD COPY OR COPIES REMAIN IN THE LIBRARY AND IF THE USER
HAS COPIES OF A REPLACEMENT FILE ON MORE THAN ONE
STRUCTURE, THE FIRST ONE ENCOUNTERED WILL BE USED.
.SK 1

^EXTRACTION:##^EXTRACTING CAUSES THE LAST COPY OF EACH FILE IN A LIBRARY,
WHICH MATCHES A LIST ENTRY, TO BE CREATED OR TO REPLACE A COPY IN
THE USER'S DIRECTORY.
