- WARNING - FNdb, FNdd and FNdw have now been deleted

- Changes from verion 1.50
- ------------------------
-
- 1.51 No need for space before the '!' writeback marker in ldm/stm
- instructions. eg. LDMIA sp!,{pc,link} is now valid. This avoids
- the old Basic bug where Basic assumed the '!' was an indirection
- operator and flagged an error.
-
- I've fixed the bug which sometimes made SWI string processing
- fail to work. So far as I am aware this now always operates as
- long as the first character of a string is upper case
-
-
- 1.52 Still more improvements to error handler. These are mainly aimed
- at finding ways to intercept errors during preprocessing in order
- to enable the first pass of the assembler to be made without
- crashing. Previously many errors discovered during preprocessing
- caused the program to quit immediately, slowing up development.
-
- Filetypes 'Module' and 'Utility' now don't need an ORG directive
- but will automatically be assembled with a 'run address' of 0.
-
- Cured bug which assumed that an object filename beginning with
- '!' meant 'no filename'. I missed it because I never followed
- the dumb convention of calling application code '!Runimage'
-
- I've corrected the 'feature' which sorted the label list in
- reverse alhabetical order. It's the right way round now!
-
- There's a short demonstration application included now. It's
- not very exiting but it's a bit better that the other example
- files. You will find it in the directory 'Demo'. It is supplied
- 'ready assembled' as well as the source files.
-
-
- 1.53 ---- NO PUBLIC RELEASE OF THIS VERSION ----
- Various internal changes.
-
- The old FNdb, FNdw and FNdd, which have been completely obsolete
- for some time, have been removed.
-
- You can now have multiple comment lines without using a ';' at
- the start of each line. If SAsm finds a '{' at the start of a
- line it will ignore EVERYTHING up to the next '}'. You can
- therefore write whole paragraphs of descriptive text. Obviously
- { and } characters are not allowed within this text. See section
- 'Descriptive text' in the Manual for more details before using.
-
- There is a new directive AREA which is used to set up a data
- area and define offsets within it. This is intended to be used
- with LDR, Rx,[<reg>,#<offset>] type instructions where <reg> is
- a register set to point to the start of the area and <offset> is
- a pre defined constant. This is quite complicated so you'll need
- to read the relevant section of the manual.
-
- OSET variable implemented to make 'poking' data into code
- easier. During assembly the variable OSET is set to a value such
- that OSET+<label> can be used to 'poke' data into the completed
- code where <label> is any global label defined in the ususal
- way. It isn't likely that you will want to do this, but if for
- any reason you do, then by using OSET you can.
-
- There was a 'bug' in the routine that trapped the 'file open'
- error which stopped it working properly. This has now been fixed
- so in theory an open error file should not now cause problems.
-
- 1.54 Minor bugs introduced in 1.53 corrected
-
- Tokenising introduced with more than 6500 lines of source code.
-
- Corrected the bug which wouldn't allow a ':' in an INCLUDE
- filename. This was due to a typing error in my source code!
