                      Rules and regulations for !Squish
-----------------------------------------------------------------------------

* Squish is not perfect. After an extremely long development time, Squish
  has reached the stage whereby it can squash any program by someone with a
  respect for 'sensible' programming. One can lecture about the principles of
  good design in today's competing environment, but no. Though suffice to
  mention a statement made by Dijkstra in 1979, on the subject of software:

  "The advent of cheap and powerful devices will put Software Engineering
   back 25 years."

  This, of course, is absolutely true.

  The BBC BASIC interpreter is quite simple. It's syntax rules are good,
  but very flexible. This allows people to tackle the subject of programming
  in very different ways. Squish uses general algorithms to reduce the size
  of programs, but there are restrictions should you want the resulting file
  to work! These are listed below, along with hints on how to avoid these.


------------------------- Restrictions with Squish --------------------------


* GOTO, GOSUB and RESTORE.

  Squish will simply ignore these commands by skipping past them. Nowadays it
  is absolutely unforgiveable to use GOTO/GOSUB so Squish will NEVER support
  these. RESTORE commands are generally OK, but

  a) don't use formula based RESTORE commands if you can avoid doing so, and
  b) don't RESTORE pointers to blank lines/REMs that will be deleted.

  Please note that, if a program has been written sensibly, it is perfectly
  possible for it's GOTO, GOSUB, and/or RESTORE commands to be squished and
  still work correctly. (Eg. RISC User's !Dustbin.)


          ----------------------------------------------------------


* DATA statements

  If a variable is an element of a DATA statement, it will need to be
  renamed along with the other references to it throughout the program.

  In DATA statements, BASIC determines a string from a variable by the fact
  that the former is enclosed within quotation marks, although the syntax
  does allow certain strings to exclude quotation marks.

  Squish works on the principle that ALL strings are enclosed within
  quotation marks. If not, the DATA element is liable to be renamed.
  For example :

  100 DATA window                <- This will be renamed
  100 DATA "window"              <- This will NOT be renamed


          ----------------------------------------------------------


* Pointless lines.

  Don't use pointless lines to separate PROCedures etc.. Use blank/commented
  lines instead, else Squish will attempt to rename the text inbetween
  (should you ask Squish to "Rename Variables", but not "Remove REMs etc."
  first.)

  Eg. :

  ENDPROC
  :
  : --- Routine to read TIME --- <- Squish will assume these are VARIABLEs
  :
  DEF PROCget_time

  The annotation of programs using REM statements is the correct method. So,
  to implement the above example :

  ENDPROC
  :
  : REM Routine to read TIME     <- Correct style, acceptable by Squish
  :
  DEF PROCget_time


          ----------------------------------------------------------


* The EVAL problem.

  This refers to FuNctions like :
  
  A% = EVAL( "FNdoodah(" + STR$ input + ")" )

  Squish sees "FNdoodah" as a constant (quite correctly) and does not rename
  it. There are other language constructs available that can be used in place
  of this method, and should be whenever possible (particularly if the
  program is to be Squished at a later date.) Note that EVAL statements which
  use FN/PROC identifiers can be used by renaming variables WITHOUT the
  "PROCs" and "FNs" options.


          ----------------------------------------------------------


-----------------------------------------------------------------------------
   Special Notes on !Squish for programmers (and other interested parties)
-----------------------------------------------------------------------------


* When determining if a line is blank, the one thing that seperates a 'dummy'
  line from a real one is if it contains a KEYWORD. The routine that checks
  for this simply scans the tokenised line for a hex value of &7F or greater.
  If this is the case, a KEYWORD is present, and the line is taken to be
  'real', regardless of whether or not it is ever executed.
  The exceptions are lines that consist of a '*' command, a line containing a
  return assignment (eg. =result$), or a line consisting solely of '[', or
  ']', as these are all valid lines containing no KEYWORDs.

* When removing SPACEs from a line, there are many conditions whereupon a
  single SPACE must be left so that the BASIC interpreter can make sense of
  what is going on. For an example, Squishing 'X = Y NOT Z' can only be
  Squished to 'X=Y NOTZ', because taking the remaining SPACE out results in
  the BASIC interpreter recognising this as an assignment, as opposed to a
  logical operation. Although Squish doesn't take all of these conditions
  into account, it still provides a more than adequate reduction rate.

* Note that recognising if you are in Assembler or not depends entirely
  upon how many '[' and ']' signs have been encountered, and when Squishing
  assembler commands, all statements are left with a single SPACE between
  each field of the statement. ';' comments are also deleted.
  (Although the idea of Squish is to Squish BASIC programs, the assembler
  Squisher has been included to improve those programs that use small amounts
  of ARM code, just to please those who like to do so.)

* To remove REM statements, Squish scans the tokenised line for the Hex
  value for 'REM'. If this is found, the line is shortened appropriately.
  This works fine, but there is one occasion when this doesn't work, and that
  is when you put a REM statement after a DATA statement, as the interpreter
  stores this as a string, failing to tokenise it.

* As mentioned above, everything following a DATA statement is stored as pure
  ASCII, and the same also applies to REM statements, so if you concatenate a
  program without removing REM statements, if 2 (or more) REMs are Squished
  together, the supplementary REMs are de-tokenised into ASCII form, which is
  why Squished REM statements look a little weird.

KJS (08-08-90) - Release version 1.00


-----------------------------------------------------------------------------
                                  History file
-----------------------------------------------------------------------------


* Amended the blank-line removal code to account for OTHERWISE statements
  being present [OTHERWISE->&7F]
* Restructured logic format for IF... statements. Previously 'dead' logic has
  now been redesigned to cope with IF... statements without THENs.
* Additional logic to ensure 'OTHERWISE' keywords start on a new line.

  KJS (10-08-90) - Release version 1.01


* Inserted additional code to rename variables.

  KJS (21-09-90) - Release version 1.02


* Variable renamer now copes with ARM code, and instructions are not
  treated as variables. (eg. LDMEQIA.)
* RESTORE statements are left alone (BASIC encodes ensuing pointers), making
  renumbering possible after compaction.
* Labels such as '.Address' are not treated as an ADD instruction (variable
  code used to check the ADD part and be fooled by this.)
* Option of fast/slow compaction inserted. Slow allows Squish to compact as
  a background task, whilst fast allows Squish to control the system during
  compaction.
* Renaming code altered to produce liberally-spread variable names, a feature
  from the old BBC days, as the interpreter takes less time to identify the
  variable it wants.

  KJS (25-09-90) - Release version 1.03


* Additional code added so that semicolon-text in Assembly language is not
  treated as variables (if you Squish a program using the rename variable
  option WITHOUT removing REMs etc., REMarks in Assembly language were
  renamed)
* Additional code also added to the renaming procedures, since, when using
  Assembly language, AND and EOR instructions are tokenised as if they were
  BASIC instructions.

  KJS (03-10-90) - Release version 1.04


* Logic in the SPACE-Squishing procedures restructured for DIM statements.
* Save-over-original option altered to a 'final-info' one, so that the old
  and new program-length, and the compression rate, may be seen.
* Procedure that removes SPACEs rewritten to be a lot speedier.

  KJS (22-10-90) - Release version 1.05


* Additional code added to cope with the BY keyword used in conjunction with
  certain graphic commands. BY itself is stored as ASCII text straight after
  the tokenised graphic keyword.

  KJS (25-10-90) - Release version 1.06


* Algorithms completely rewritten in ARM Code.
* Algorithms VASTLY improved.
  (Has competently Squished everything tried so far.)
* Windows redrawn from scratch.
* User interface completely rewritten in C.

  KJS (22-08-91) - Release version 2.00


* User interface
    - bugs sorted out.
    - made completely !Help compatible.
    - pause facility / swap between fast & slow options implemented
    - etc. etc.

  Izzy (26-10-91) - Release version 2.10


* ARM and C interface recoded to allow >8k programs to be loaded and have
  their variables compacted. Filename extraction for in-memory-data-transfers
  implemented (so why doesn't everyone else use it?)

  Izzy (23-11-91) - Release version 2.11


* Problem with 'flex_midextend' cured by using 'flex_extend' instead.

  Izzy (24-12-91) - Release version 2.12


* 'Rename under flex' bugs solved. Only ALI-vars still remain a problem.

  KJS (31-12-91) - Release version 2.14 (2.13 is unlucky, man!)


* DIV and MOD spacing problems removed (why had I not noticed this before?)
  All variables now forced to lower-case to remove FN/PC/IF/ON problems
  (why had I not noticed this either?!)

  KJS (12-01-92) - Release version 2.15


* Renaming of program variables vastly restructured. Now renames ARM Code
  variables properly, without renaming shift mnemonics. Help file redone
  to a more 'serious programmer attitude' style ... NOT!

  KJS (26-01-92) - Release version 2.16


* Minor modifications to run under RISC OS 3.10

  Izzy (18-12-92) - Release version 2.17


* Major modifications to run under RISC OS 3.10. Squish can now save without
  constantly falling over.

  Izzy (07-01-93) - Release version 2.18


* Help system rewritten. Templates generally 'tidied' up. Modification to
  SPACE remover to correctly handle removal of multiple SPACEs within
  particular DIM statements.

  KJS (08-01-93) - Release version 2.19


* ERROR EXT problem solved. OPT problem solved, specifically renaming of 1
  character pass variables. Register renaming solved. Can now rename ARM
  registers that have been assigned to 1 character variable names. Anomalies
  with C interface (WIMP drags, IMDTs etc.) solved. Validation of BASIC file
  included, as per !Edit. BackDrop icon created. Adjust click on main window
  forces filer window to appear.

  KJS (11-01-93) - Release version 2.20


* REM removal code rewritten. Squish can now remove comments from ARM
  assembler correctly. (Assembler can have further statements after a
  comment, BASIC can't.)
* Variable renamer changed to cope with the rewritten REM code. Can now
  rename variables AFTER concatenation, without renaming all the embedded
  ARM comments.
* Save routines now made more robust.

  KJS / Izzy (13-01-93) - Release version 2.21


* C interface updated. RAM transfers work correctly. Interface examined for
  consistency.
* ARM routines compared to BASIC CRUNCH command - ARM routines found to be
  somewhat better.
* Save routine now suffixes filename with S or Q as appropriate. Code fixed
  to prevent renaming ARM variables that begin with a register definition
  (eg. "r13pointer"). Problem with *commands solved.

  KJS / Izzy (19-01-93) - Release version 2.22


* A 'bug' in the "Pause" feature removed. If squishing is paused, pressing
  either the Cancel or the Fast icon failed to reset the Pause status, and
  subsequent icons reflected erroneous states.

  KJS (24-02-93) - Release version 2.23


* SERIOUS problem in the messaging system removed, which had only became
  apparent after release RISC OS 3.10 was fitted. Option added to the Rename
  algorithm to allow suppression of renaming PROCEDURE and/or FUNCTION
  identifiers.

  KJS/Izzy (25-02-93) - Release version 2.24


* Dialogue box handler code completely re-written. Squish can now be quit
  from the menu without a problem. Modified RAM save routine slightly -
  now if you save using an in-memory data transfer the data is considered
  safe. It will be up to the other package to warn the user that the data
  is unsafe, since Squish will by now have effectively finished processing.
* Bug in rename variables fixed. If a *command was part of an IF...THEN
  construct, it was renamed.

  Izzy (01-03-93) - Release version 2.25


* Put in code to differentiate between a PREQUIT message being application
  specific / a general desktop shutdown routine.

  Izzy (02-03-93) - Release version 2.26


* Completely re-wrote dialogue box code. All dboxes now self-centre across
  MODE changes.
* Changed the code back so that in-memory data transfers are NOT considered
  safe.
* Options for squishing are now automatically displayed if none are selected
  when attempting to squish a program.
* Messages file and templates tidied up. Help messages for menus taken out
  as not supported by the current C compiler.

  Izzy (03-03-93) - Release version 2.27


* Squish will now intelligently deal with an attempt to quit the program.
* The RISC OS desktop boot file facility is also now supported.
* Extra code inserted to allow identifiers to be 'locked' from renaming.
  Principally, this allows libraries to have global PROC/FN/vars exported
  to individual RunImages without the need to concatenate, also retaining
  their uncompressed format. The syntax for listing identifiers is held
  within REM statements in the source program, as per example :

  100 REM LOCK <identifier 1> , <identifier 2> , ... , <identifier n>

  so a WIMP program which uses a global WIMP procedure library may
  have a LOCK statement something like this :

  100 REM LOCK PROCopen_window , PROCclose_window , WINDOW% , ICON_TEXT$

  Of course, both the main RunImage AND the library itself will need to have
  a copy of the LOCK statements, else one will have it's identifiers renamed
  and the other won't. Also note that subscripts must be omitted, so a LOCK
  cannot have something like this :

  100 REM LOCK PROCedure_OpenWindow( x% )     <- the "( x% )" should be
                                                 omitted from this line

  KJS/Izzy (17-03-93) - Release version 2.28


* C interface now allows multiple re-squish attempts without losing the list
  of LOCKed variables. Also advises when re-squishing may be advisable due to
  lack of memory when renaming variables.
* All calculations on savings are now based on the original program size.
* Help now given on SAVE dialogue box.

  Izzy (18-03-93) - Release version 2.29


* Bug in variable renamer fixed. One character identifiers caused problems
  in some places, especially in the third opcode field, in use as an
  immediate (eg. #X).

  KJS (19-03-93) - Release version 2.30


* Put in new save routines to use the drag-a-sprite facility.

  Izzy (21-03-93) - Release version 2.31


* Iconise facility implemented fully. Now when iconised, Squish will
  continue to process the BASIC program. When finished the iconbar
  sprite will change to indicate that the process has been completed,
  but that the window is still iconised. Double click on the iconised
  window to continue. Also fixed minor bug when using ADJUST on the
  close window icon to open the programs directory.

  Izzy (01-04-93) - Release version 2.32


* Patch over initialisation routines to cope with new Wimp_Initialise
  specification, as C library doesn't allow for this.

  Izzy (03-04-93) - Release version 2.33


* Patch over 'wimpt' routines. Had to insert our task handle into the
  'wimpt' routines workspace directly, as Acorn have forgotten to tell
  us that 'xfer_send' uses, for in memory data transfers, the 'wimpt_task'
  function - which meant that Squish version 2.33 fell over when doing
  in-memory data transfers.

  Izzy (06-04-93) - Release version 2.34


* Put in hourglass routines to include the LED indicator and changed
  message warning order when you attempt to Squish a program.

              No LED : Initialising general internal routines,
             Top LED : Extracting LOCK information,
          Bottom LED : Initialising variables.
   

* SYS reduction code altered, so that renaming of OS_WriteC (SYS &0)
  does not have it's only zero stripped off by the leading_zero code.

  KJS/Izzy (07-04-93) - Release version 2.35


* Fixed * command bug.

  KJS (15-04-93) - Release version 2.36


* Adjusted !Run file so as not to re-instate a CLib that is already active.

  Izzy (10-05-93) - Release version 2.37


* Removed bug in EOL removal code. Now removes EOL rubbish, without also
  removing out of bound characters at the end of a * command.

  KJS (29-07-93) - Release version 2.38


-----------------------------------------------------------------------------
                                  Special note
-----------------------------------------------------------------------------

* After concatenation, although the tokenised line may be less than or equal
  to 255 bytes long, the UNtokenised may be a lot longer. BASIC editors do
  not like this (sad isn't it?) and kick up errors of the sort : 'Line xxxx
  is too long to be edited.'. Please note that this is not a 'bug' with
  Squish, but a limitation of the editors.
