+## Known Issues
+
+CP/M (and workalike) OSes have significant restrictions on filename
+characters.  The FAT application will block any attempt to create a
+file on the CP/M filesystem containing any of these prohibited
+characters:
+
+|         `< > . , ; : = ? * [ ] _ % | ( ) / \`
+
+The operation will be aborted with "`Error: Invalid Path Name`" if such
+a filename character is encountered.
+
+Since MS-DOS does allow some of these characters, you can have
+issues when copying files from MS-DOS to CP/M if the MS-DOS filenames
+use these characters.  Unfortunately, FAT is not yet smart enough to
+substitute illegal characters with legal ones.  So, you will need to
+clean the filenames before trying to copy them to CP/M.
+
+The FAT application does try to detect the scenario where you are
+copying a file to itself.  However, this detection is not perfect and
+can corrupt a file if it occurs.  Be careful to avoid this.

+# WDATE
+
+`wdate` is a utility for CP/M systems that have Wayne Warthen's
+ROMWBW firmware. It reads or sets the real-time clock, using function
+calls in the BIOS. It should work on any RTC device that is supported by
+ROMWBW, including the internal interrupt-driven timer that is is available
+on some systems. 
+
+`wdate` differs from the `rtc.com` utility that is provided with the
+ROMWBW version of CP/M in that it only gets and sets the date/time. 
+`rtc.com` can also manipulate the nonvolatile RAM in certain clock
+devices, and modify the charge controller. However, `wdate` is (I would
+argue) easier to use, as it takes its input from the command line, which
+can be edited, and it's less fussy about the format. It doesn't require
+the date to be set if you only want to change the time, for example.
+ In addition, `wdate` has at least some error checking.
+
+`wdate` displays the day-of-week and month as English text, not 
+numbers. It calculates the day-of-week from the year, month, and day.
+RTC chips usually store a day-of-week value, but it's useless in this
+application for two reasons: first, the BIOS does not expose it. Second,
+there is no universally-accepted way to interpret it (which day does
+the week start on? Is '0' a valid day of the week?)
+
+## Syntax
+
+| `WDATE`
+| `WDATE ` *`<hr> <min>`*
+| `WDATE ` *`<hr> <min> <sec>`*
+| `WDATE ` *`<year> <month> <day> <hr> <min> <sec>`*

+two-digit year starts at 2000. 
+
+    A> wdate /?
+
+Show a summary of the command-line usage.
+
+## Notes
+
+I've tested this utility with the DS1302 clock board designed by Ed 
+Brindly, and on the interrupt-driven timer built into my Z180 board. 
+However, it does not interact with hardware, only BIOS; I would expect 
+it to work with other hardware.
+
+wdate checks for the non-existence of ROMWBW, and also for failing 
+operations on the RTC. It will display the terse "No RTC" message in 
+both cases.
+
+The ROMWBW functions that manipulate the date and time operate on BCD 
+numbers, as RTC chips themselves usually do. wdate works in decimal, so 
+that it can check that the user input makes sense. A substantial part of
+the program's code is taken up by number format conversion and range 
+checking.
+
+## Etymology
+
+The `WDATE` application was written and contributed by Kevin Boone.
+The source code is available on GitHub at

+style display and associated hex keypad.
+
+HBIOS only supports a single DSKY device since there is no reason to have
+more than one at a time.  The DSKY unit is assigned a Device Type ID 
+which indicates the specific hardware device driver that handles the 
+unit.  The table below enumerates these values.

+
+                         Generic CP/M Version 3.00
+
+                    (C) Copyright R.T.Russell 1982-1999
+
+1. INTRODUCTION
+
+   BBC  BASIC (Z80) has been designed to be as compatible as  possible  with 
+   Version 4 of the 6502 BBC BASIC resident in the BBC Micro Master  series.  
+   The language syntax is not always identical to that of the 6502  version, 
+   but in most cases the Z80 version is more tolerant.
+
+   BBC  BASIC (Z80) is as machine independent as possible and, as  supplied, 
+   it  will  run  on any CP/M 2.2 (or later) system using  a  Z80  processor 
+   (checks  are carried out to ensure that the processor is a Z80  and  that 
+   the version of CP/M is at least 2.2).  It is minimally configured for  an 
+   ADM3a-compatible VDU.
+
+   Few  CP/M  systems  offer  colour graphics of  the  quality  provided  as 
+   standard  on  the BBC Microcomputer, and no software can  provide  colour 
+   high-resolution graphics from a monochrome character-orientated computer.  
+   However,  many CP/M system users are interested in the  advanced  program 
+   structures  available from BBC BASIC and, within the limitations  of  the 
+   host  computer, BBC BASIC (Z80) provides the programming  structures  and 
+   the non-graphic commands and functions specified for BBC BASIC.
+
+   In order to make full use of the facilities available in BBC BASIC  (Z80) 
+   it is necessary to install a small patch to adapt it to the  capabilities 
+   of  the  host  computer.  The source code of the  patch  present  in  the 
+   distribution version is supplied as BBCDIST.MAC.
+
+   This  documentation  should be read in conjunction with  a  standard  BBC 
+   BASIC  manual.  Only those features which differ from the standard  Acorn 
+   versions are documented here.
+
+
+2. MEMORY UTILISATION
+
+   BBC  BASIC (Z80) requires about 16 Kbytes of code space, resulting  in  a 
+   value  of  PAGE  of about &3E00.  The remainder of  the  user  memory  is 
+   available  for BASIC programs, variables (heap) and stack.  Depending  on 
+   the system configuration, HIMEM can have a value up to &FE00.
+
+
+3. COMMANDS, STATEMENTS AND FUNCTIONS
+
+   The syntax of BASIC commands,  statements and functions is in most  cases 
+   identical  to  that  of  the  BBC  Micro  version  (BASIC  4).   The  few 
+   differences are documented here:
+
+   ADVAL
+   This function is not implemented.
+
+   CALL
+   CALL  sets  up a table in RAM containing details of the  parameters;  the 
+   processor's  IX register is set to the address of this  parameter  table.  
+   The other processor registers are initialised as follows:
+
+               A is initialised to the least significant byte of A%
+               B is initialised to the least significant byte of B%
+               C is initialised to the least significant byte of C%
+               D is initialised to the least significant byte of D%
+               E is initialised to the least significant byte of E%
+               F is initialised to the least significant byte of F%
+               H is initialised to the least significant byte of H%
+               L is initialised to the least significant byte of L%
+
+   The parameter types are:
+
+          Code No.       Parameter Type      Example
+              0          Byte (8 bits)       ?A%
+              4          Word (32 bits)      !A% or A%
+              5          Real (40 bits)      A
+            128          Fixed string        $A%
+            129          Movable string      A$
+
+   On  entry  to the subroutine the parameter table contains  the  following 
+   values:
+
+          Number of parameters     1 byte (at IX)
+
+          Parameter type           1 byte (at IX+1)
+          Parameter address        2 bytes (at IX+2, IX+3, LSB first)
+
+          Parameter type           ) repeated as often as necessary
+          Parameter address        )
+
+   Except  in  the case of a movable string (normal  string  variable),  the 
+   parameter  address  given is the absolute address at which  the  item  is 
+   stored.  In the case of movable strings (type 129) it is the address of a 
+   4-byte parameter block containing the current length, the maximum  length 
+   and the start address of the string (LSB first) in that order.
+
+   Integer  variables  are stored in twos complement form with  their  least 
+   significant byte first.
+
+   Fixed  strings are stored as the characters of the string followed  by  a 
+   carriage return (&0D).
+
+   Floating point variables are stored in binary floating point format  with 
+   their least significant byte first; the fifth byte is the exponent.   The 
+   mantissa  is  stored as a binary fraction in sign and  magnitude  format.  
+   Bit 7 of the most significant byte is the sign bit and, for the  purposes 
+   of calculating the magnitude of the number, this bit is assumed to be set 
+   to  one.  The exponent is stored as an integer in excess 127  format  (to 
+   find the exponent subtract 127 from the value in the fifth byte).
+
+   If the exponent byte of a floating point number is zero, the number is an 
+   integer stored in integer format in the mantissa bytes.  Thus an  integer 
+   can be represented in two different ways in a real variable.  For example 
+   the value +5 can be stored as:
+
+            05 00 00 00 00         Integer 5
+            00 00 00 20 82         (0.5 + 0.125) * 2^3
+
+   COLOUR (COLOR)
+   This statement is not implemented.
+
+   DRAW
+   This statement is not implemented.
+
+   EDIT
+   A command to edit or concatenate and edit the specified program  line(s).  
+   The specified lines (including their line numbers) are listed as a single 
+   line.   By changing only the line number you can use EDIT to duplicate  a 
+   line.
+
+     EDIT 230
+     EDIT 200,230
+
+   The  following control functions are active both in the EDIT mode and  in 
+   the immediate entry mode (i.e. at the BASIC prompt):
+
+     Move the cursor one character position to the left
+     Move the cursor one character position to the right
+     Move the cursor to the start of the line
+     Move the cursor to the end of the line
+     Insert a space at the current cursor position
+     Delete the character at the current cursor position
+     Backspace and delete the character to the left of the cursor
+     Delete all characters to the left of the cursor
+     Delete all characters from the cursor to the end of the line
+
+   The choice of which keys activate these functions is made when BBC  BASIC 
+   is configured for a particular system.  The distribution version uses ^H, 
+   ^I, ^K, ^J, ^A, ^E, DEL (&7F), ^L and ^X.
+
+   To exit EDIT mode and replace the edited line, type RETURN (ENTER).
+
+   To abort the edit and leave the line unchanged, type ESCape.
+
+   ENVELOPE
+   This statement is not implemented.
+
+   GET
+   This  function  waits for a character to be typed at  the  keyboard,  and 
+   returns the ASCII code.
+
+   GET can also be used to read data from a processor I/O port; full  16-bit 
+   port addressing is available:
+
+          N% = GET(X%) : REM input from port X%
+
+   INKEY
+   This function waits for a specified maximum number of centiseconds for  a 
+   character to be typed at the keyboard.  If no character is typed in  that 
+   time, the value -1 is returned.  In the distribution version the delay is 
+   determined by a simple software timing loop, and may be very  inaccurate.  
+   The customisation patch allows this to be adjusted to suit the system  in 
+   use.
+
+   INPUT#
+   The format of data files is different from that used by the BBC Micro, in 
+   part  to improve compatibility with standard CP/M files.  Numeric  values 
+   are  stored  as five bytes in the format documented under  CALL;  if  the 
+   fifth  byte is zero the value is an integer.  Strings are stored  as  the 
+   characters  of the string (in the correct order!) followed by a  carriage 
+   return (&0D).
+
+   MODE
+   This statement is not implemented.
+
+   MOVE
+   This statement is not implemented.
+
+   PLOT
+   This statement is not implemented.
+
+   POINT
+   This function is not implemented.
+
+   PRINT#

+   are  stored  as five bytes in the format documented under  CALL;  if  the

+
+   PUT
+   A  statement to output data to a processor port.  Full 16-bit  addressing 
+   is available.
+
+          PUT A%,N% : REM Output N% to port A%
+
+   SOUND
+   This statement is not implemented.
+
+   TIME
+   This pseudo-variable is not implemented in the distribution version,  but 
+   can be supported by means of the customisation patch.  See BBCDIST.MAC.
+
+   USR
+   As with CALL, the processor's registers are initialised as follows:
+
+               A is initialised to the least significant byte of A%
+               B is initialised to the least significant byte of B%
+               C is initialised to the least significant byte of C%
+               D is initialised to the least significant byte of D%
+               E is initialised to the least significant byte of E%
+               F is initialised to the least significant byte of F%
+               H is initialised to the least significant byte of H%
+               L is initialised to the least significant byte of L%
+
+   USR returns a 32-bit integer result composed of the processor's H, L,  H' 
+   and L' registers, with H being the most significant.
+
+
+4. RESIDENT Z80 ASSEMBLER
+
+   The  in-line  assembler is accessed in exactly the same way as  the  6502 
+   assembler  in  the BBC Micro version of BBC BASIC.  That is,  '['  enters 
+   assembler mode and ']' exits assembler mode.
+
+   All  standard  Zilog  mnemonics are accepted: ADD, ADC and  SBC  must  be 
+   followed by A or HL.  For example, ADD A,C is accepted but ADD C is  not.  
+   However, the brackets around the port number in IN and OUT are  optional.  
+   Thus  both OUT (5),A and OUT 5,A are accepted.  The instruction IN  F,(C) 
+   is not accepted, but the equivalent code is produced from IN (HL),C
+
+   The pseudo-ops DEFB, DEFW and DEFM are included.  DEFM works like EQUS in 
+   the 6502 version.
+
+
+5. OPERATING SYSTEM INTERFACE
+
+   The   following   resident  Operating  System   ("star")   commands   are 
+   implemented.  They may be accessed directly (e.g. *BYE) or via the  OSCLI 
+   statement (OSCLI "BYE").
+
+   Control characters, lower-case characters, DEL and quotation marks may be 
+   incorporated in filenames by using the 'escape' character '|'.   However, 
+   there is no equivalent to the BBC Microcomputer's '|!' to set bit 7.
+
+   *BYE
+   Returns control to the operating system (CP/M).
+
+   *CPM
+   Same as *BYE.
+
+   *. [filespec]
+   *DIR [filespec]
+   List  the  files which match the (optional) ambiguous  filespec.  If  the 
+   filespec is omitted, all .BBC files are listed:
+               *DIR           List all .BBC files on the disk
+               *DIR B:*.*     List all files on disk B:
+               *.*.*          List all files on the current disk
+
+   *DRIVE d:
+   Select drive d as the default drive for subsequent disk operations.
+
+   *ERA filespec
+   Erase (delete) the specified disk file or files.  The extension  defaults 
+   to .BBC if omitted.
+
+   *ESC [ON|OFF]
+   *ESC OFF disables the abort action of the ESCape key; after *ESC OFF  the 
+   ESCape  key  simply returns the ASCII code ESC (27).  *ESC ON,  or  *ESC, 
+   restores the normal action of the ESCape key.
+
+   *EXEC filespec
+   Accept  console  input  from  the  specified file  instead  of  from  the 
+   keyboard. If the extension is omitted, .BBC is assumed.
+
+   *LOAD filespec aaaa
+   Loads  the specified file into memory at address aaaa. The  load  address 
+   must be specified. If the extension is omitted, .BBC is assumed.
+
+   *OPT [n]
+   Select  the destination for console output characters.  The value n is in 
+   the range 0 to 2, as follows:
+               
+          0    Send characters to the console output
+          1    Send characters to the auxiliary output
+          2    Send characters to the printer (list) output
+
+   *REN newfile=oldfile
+   *RENAME newfile=oldfile
+   Renames  'oldfile'  as 'newfile'.  If the extension is omitted,  .BBC  is 
+   assumed.
+
+   *RESET
+   Rest the disk system (CP/M function 13).  This command does not close any 
+   files  nor does it perform any other housekeeping function.   You  should 
+   use *RESET after you have changed a disk.
+
+   *SAVE filespec aaaa bbbb
+   *SAVE filespec aaaa +llll
+   This command saves a specified range of memory to disk. The address range 
+   is  specified either as start (aaaa) and end+1 (bbbb) or as start  (aaaa) 
+   and length (llll). If the extension is omitted, .BBC is assumed.
+
+   *SPOOL [filespec]
+   Copy all subsequent console output to the specified file. If the filename 
+   is omitted,  any current spool file is closed and spooling is terminated. 
+   If the extension is omitted, .BBC is assumed.
+
+   *TYPE filespec
+   Type the specified file to the screen. If the extension is omitted,  .BBC 
+   is assumed.
+
+   *| comment
+   This is a comment line. Anything following the | is ignored.
