-                           DDTZ v2.7
-                       by C.B. Falconer
-                  edited by George A. Havach
-
-Introduction:
-============
-DDTZ v2.7 is a complete replacement for DDT,  Digital  Research's 
-famous Dynamic Debugging Tool,  with improved functionality,  bug 
-extermination,  and full Z80 support.  In general,  DDTZ is fully 
-compatible  with  the  original utility,  but it  has  extra  and 
-extended  commands  and  many  fewer  quirks.   All  Z80-specific 
-instructions can be (dis)assembled,  though in Intel rather  then 
-Zilog format. Furthermore, DDTZ will correctly trace ('T' and 'U' 
-commands) both 8080 and Z80 instructions,  depending on which CPU 
-is operating.  On startup,  the program announces which CPU it is 
-running on.
-
-DDTZ v2.7 now handles the 64180 added opcodes.  It does NOT  test 
-for  a  64180 CPU,  since this cannot be done  without  executing 
-illegal   Z80  instructions,   which  in  turn  will  crash  some 
-simulators.  However v2.7 does not execute any 64180 instructions 
-internally, only in the subject program.
-
-This  issue supplies the "M" version assembled,  to avoid  errors 
-when switching between MSDOS and CPM systems.   The command table 
-is updated accordingly.  Most CPM users are also MSDOS users, but 
-not vice-versa.
-
-The program is invoked by typing
-
-      ddtz<ret>
-or
-      ddtz [d:]filespec<ret>
-
-In  the  second  form,  DDTZ will load the  specified  file  into  
-memory starting at 0100H,  unless it's a .HEX file that sets  its 
-own  load  address.  Besides reporting the NEXT free address  and  
-the PC (program counter) after a successful load, DDTZ also shows 
-the number of memory pages needed for a SAVE.  Instead of  having 
-to write all this down,  just use the 'X' command at any time  to 
-redisplay these three values for the current application.
-
-NOTE:  loading  more  code above the NEXT pointer  revises  these 
-       values.
-
-As  in DDT,  when a program is loaded above the area holding  the 
-'A'  and  'U'  (and now 'W') command  code,  these  commands  are 
-disabled,  and the extra memory  is released to the user.   Thus,  
-DDTZ can occupy  as little as 3K total memory space.  Unlike DDT,  
-however,  DDTZ will not overwrite itself or the system on program 
-loads (except .HEX files).
-
-At initialization,  the stack pointer (SP) points to a return  to 
-DDTZ,  just like for the CCP. Thus, programs that normally return 
-to   the  CCP  will  be  returned  to  DDTZ.    The  'B'  command  
-reinitializes this condition.
-
-
-The intercept vector copies  the BDOS version number,   etc.,  so 
-an  object program  does not know that  DDTZ is running   (except 
-for BIOS-BDOS vector size). Thus, programs that check the version 
-number should execute correctly under DDTZ.
-
-All input parameters can now be entered in any of three formats:
-
-       (1) hexadecimal (as in DDT),
-       (2) decimal, by adding a leading '#' character,
-       (3) ASCII, by enclosing between either single or double
-           quotes; either one or two characters are allowed.
-
-Leading  blanks  in  command lines and parameters  are  absorbed. 
-Either  a  comma  or a (single) space   is   a  valid  delimiter.   
-Either uppercase or lowercase input is accepted.
-
-The  default command  (for anything  not otherwise  recognizable)  
-is 'H'.  This allows convenient calculation, along with the other 
-features described below.   So,  to convert a number,  just enter 
-it!
-
-As  in  DDT,   the prompt character is '-',  and the  only  error 
-message  is  the query ('?'),  which generally kicks you back  to 
-command mode. 
-
-New Commands (Over DDT):
-=======================
-
-NOTE: letters in parenthesis,  e.g.  "(U)",  show the  equivalent 
-      command for DDTZM version (compatible with MSDOS debug).
-
-   @  Sets  or  shows (with no parameter)  the internally  stored 
-      "base" value.   Also used with the 'S' and 'D' commands  as 
-      an optional parameter  (though without the '@')  to display 
-      memory  from an arbitrary base marker (offset). When set to 
-      zero (the default), it does not affect any screen displays.
-
-   B  B)egin: resets the USER stack pointer to its initial value, 
-      such  that any program that exits by an RET will return  to 
-      DDTZ.   DDTZ   provides    a  default   stack   space    of 
-      approximately 24 bytes for user programs.
-
-   C  C)ompare first_address,last_address,against_address:  shows 
-      all  the byte differences between two memory areas,  in the 
-      format
-
-       XXXX aa YYYY bb
-
-      where  XXXX and YYYY  are the comparative memory addresses, 
-      and aa  and  bb  are the corresponding byte values.  Can be 
-      used  to  verify   the identity  of  two  files   by  first 
-      loading  them   into  different memory areas with  the  'R' 
-      command (see below).
-
-
-   W  Write:   stores the modified memory area to disk under  the 
-  (K) filename  specified  by the 'I'  command,  overwriting  the 
-      original file from which it was loaded (the user is queried 
-      before  doing  so).  By default,  the image of memory  from 
-      0100H through the "NEXT" value -1 is saved.  "K first_addr, 
-      last_address"  overrides this and allows writing ANY memory 
-      area to a file. Almost a necessity for CPM 3.0 (no SAVE!).
-      K)eep on DDTZ
-
-   X  eXamine:  redisplays the "NEXT PC SAVE" report at any time.
-  (Q) Q)uery size on DDTZ.
-
-   S  S)earch  first_address,   last_addr,  value:  searches  the 
-  (W) specified memory area for the value (a 16-bit word,  not  a 
-      byte) and shows the locations of all such.  Very useful for 
-      finding  CALL's  or JMP's to a particular address, etc.
-      W)here on DDTZ
-
-   Y  Y)our_option  parm1,parm2,address:  executes  an  arbitrary 
-      routine  at  the  specified address,   with the BC  and  DE 
-      registers  set to parm1 and parm2, respectively.
-
-   Z  Displays (but does not alter) the Z80's alternate  register 
-      set,  including the index registers (disabled if running on 
-      an  8080).  On Z80's,   automatically included  as the last 
-      part of the display by the 'X' command.
-
-
-Based (Offset) Displays:
-=======================
- 
-The  'D' and 'E' commands  can use a stored base value  (offset),  
-as  set  by   the  '@' command.   The current  @  value   may  be 
-overridden for a single execution of these commands by adding the 
-base as an extra parameter  in the command line.   The effect  is  
-to  add  this  value   to  the  first/last  address  and  display 
-accordingly.  The address listing on the left becomes  XXXX:YYYY,  
-where  XXXX  is the offset address and YYYY is the actual  memory 
-address being displayed.   For example,  if you have a data  area  
-located at  42B7H  and wish to  preserve easy access,  just enter 
-"@42b7".  Now, "d0,3f" will dump memory starting at 4237H.
-
-
-Further Changes from DDT:
-========================
-
-   A  A)ssemble  now  accepts   the  full Z80  as  well  as  8080 
-      instruction  set,  although it expects them in Intel rather 
-      than  Zilog  format  (see  notes  below   under   the   'L' 
-      command).    When in doubt, see the mnemnonic list below.
-
-   D  D)isplay or D)ump  will accept  an optional third parameter  
-      to  set the base value for a single execution only.  Format 
-      has been cleaned up.
-
-   H  H)ex_arithmetic    on   two  values   also   shows    their 
-      difference  in decimal.  With only one value,  converts  to 
-      hexadecimal, decimal, and ASCII (low-order byte only).
-
-
-   N  N)ame  now allows drive specification  (d:...)  and sets up 
-  (I) the  complete  command  line,   including  both  FCB's  (at 
-      addresses 005CH and 006CH).   The tail (stored at 0081H up) 
-      is NOT upshifted.
-      I)nput on DDTZ
-
-   U  U)nassemble now displays the raw hexcode,  especially handy 
-  (L) when examining non-code areas. Intel (8080 style) mnemonics 
-      are  used,  so  some  disassembled  instructions  may  look 
-      strange.  E.g., the Z80's 'IN B,(C)' and 'OUT (C),B' become  
-      'INP B' and 'OUTP B', respectively;  'LD (nnnn),BC' becomes 
-      'SBCD nnnn',  'ADD IX,  BC' becomes 'DADX B', and 'JP (IX)' 
-      becomes 'PCIX'. 
-      L)ist on DDTZ
-
-   L  L)oad   now  permits  loading a file into memory   with  an 
-  (R) offset,  which  is  added to the default  load  address  of 
-      0100H.   When reading in  a .HEX file  with  a preset bias,  
-      the   'R'  command will not transfer control to an  invalid 
-      execution point.  Another execution of the 'R' command will 
-      reread the input file, e.g.:
-
-         n blah<ret>
-         l<ret>
-         ...modify the code and generally mess about...
-         l<ret>
-
-      The original file  is reloaded,  and the modifications  are 
-      removed.
-      R)ead on DDTZ
-
-   E  E)nter,  like  D)isplay,  now  accepts an  optional  second 
-  (S) parameter  to  set the base value for  a  single  execution 
-      only.
-      S)ubstitute or S)et on DDTZ
-
-   T  T)rap/trace   on  termination  now shows  the complete  CPU 
-      state. Traps and traces no longer lock up  when  a user RST 
-      7 instruction is executed.   Tracing of BDOS/BIOS calls  is 
-      heavily trun cated,  avoiding clutter and preventing system 
-      crashes.
-
-NOTE: Most of the UNDOCUMENTED Z80 op-codes are handled.  Others
-      can crash the system.
-
-   R  R)egisters  also shows what two-byte values the HL  and  SP 
-  (X) registers are actually pointing to.  On Z80's, displays the 
-      alternate register set.
-      eX)amine on DDTZ
-
-NOTE: Any  use  of the 'W' or 'L' command  resets the system  DMA 
-      transfer address to the standard default value of 0080H.

-                           DDTZ v2.7
-                       by C.B. Falconer

-Introduction:
-============
-DDTZ v2.7 is a complete replacement for DDT,  Digital  Research's 
-famous Dynamic Debugging Tool,  with improved functionality,  bug 
-extermination,  and full Z80 support.  In general,  DDTZ is fully 
-compatible  with  the  original utility,  but it  has  extra  and 
-extended  commands  and  many  fewer  quirks.   All  Z80-specific 
-instructions can be (dis)assembled,  though in Intel rather  then 
-Zilog format. Furthermore, DDTZ will correctly trace ('T' and 'U' 
-commands) both 8080 and Z80 instructions,  depending on which CPU 
-is operating.  On startup,  the program announces which CPU it is 
-running on.
-
-DDTZ v2.7 now handles the 64180 added opcodes.  It does NOT  test 
-for  a  64180 CPU,  since this cannot be done  without  executing 
-illegal   Z80  instructions,   which  in  turn  will  crash  some 
-simulators.  However v2.7 does not execute any 64180 instructions 
-internally, only in the subject program.
-
-This  issue supplies the "M" version assembled,  to avoid  errors 
-when switching between MSDOS and CPM systems.   The command table 
-is updated accordingly.  Most CPM users are also MSDOS users, but 
-not vice-versa.
-
-The program is invoked by typing
-
-      ddtz<ret>
-or
-      ddtz [d:]filespec<ret>
-
-In  the  second  form,  DDTZ will load the  specified  file  into  
-memory starting at 0100H,  unless it's a .HEX file that sets  its 
-own  load  address.  Besides reporting the NEXT free address  and  
-the PC (program counter) after a successful load, DDTZ also shows 
-the number of memory pages needed for a SAVE.  Instead of  having 
-to write all this down,  just use the 'X' command at any time  to 
-redisplay these three values for the current application.
-
-NOTE:  loading  more  code above the NEXT pointer  revises  these 
-       values.
-
-As  in DDT,  when a program is loaded above the area holding  the 
-'A'  and  'U'  (and now 'W') command  code,  these  commands  are 
-disabled,  and the extra memory  is released to the user.   Thus,  
-DDTZ can occupy  as little as 3K total memory space.  Unlike DDT,  
-however,  DDTZ will not overwrite itself or the system on program 
-loads (except .HEX files).
-
-At initialization,  the stack pointer (SP) points to a return  to 
-DDTZ,  just like for the CCP. Thus, programs that normally return 
-to   the  CCP  will  be  returned  to  DDTZ.    The  'B'  command  
-reinitializes this condition.
-
-
-The intercept vector copies  the BDOS version number,   etc.,  so 
-an  object program  does not know that  DDTZ is running   (except 
-for BIOS-BDOS vector size). Thus, programs that check the version 
-number should execute correctly under DDTZ.
-
-All input parameters can now be entered in any of three formats:

-       (1) hexadecimal (as in DDT),
-       (2) decimal, by adding a leading '#' character,
-       (3) ASCII, by enclosing between either single or double
-           quotes; either one or two characters are allowed.
-
-Leading  blanks  in  command lines and parameters  are  absorbed. 
-Either  a  comma  or a (single) space   is   a  valid  delimiter.   
-Either uppercase or lowercase input is accepted.
-
-The  default command  (for anything  not otherwise  recognizable)  
-is 'H'.  This allows convenient calculation, along with the other 
-features described below.   So,  to convert a number,  just enter 
-it!
-
-As  in  DDT,   the prompt character is '-',  and the  only  error 
-message  is  the query ('?'),  which generally kicks you back  to 
-command mode. 
-
-New Commands (Over DDT):
-=======================
-
-NOTE: letters in parenthesis,  e.g.  "(U)",  show the  equivalent 
-      command for DDTZM version (compatible with MSDOS debug).
-
-   @  Sets  or  shows (with no parameter)  the internally  stored 
-      "base" value.   Also used with the 'S' and 'D' commands  as 
-      an optional parameter  (though without the '@')  to display 
-      memory  from an arbitrary base marker (offset). When set to 
-      zero (the default), it does not affect any screen displays.
-
-   B  B)egin: resets the USER stack pointer to its initial value, 
-      such  that any program that exits by an RET will return  to 
-      DDTZ.   DDTZ   provides    a  default   stack   space    of 
-      approximately 24 bytes for user programs.
-
-   C  C)ompare first_address,last_address,against_address:  shows 
-      all  the byte differences between two memory areas,  in the 
-      format
-
-       XXXX aa YYYY bb
-
-      where  XXXX and YYYY  are the comparative memory addresses, 
-      and aa  and  bb  are the corresponding byte values.  Can be 
-      used  to  verify   the identity  of  two  files   by  first 
-      loading  them   into  different memory areas with  the  'R' 
-      command (see below).
-
-
-   W  Write:   stores the modified memory area to disk under  the 
-  (K) filename  specified  by the 'I'  command,  overwriting  the 
-      original file from which it was loaded (the user is queried 
-      before  doing  so).  By default,  the image of memory  from 
-      0100H through the "NEXT" value -1 is saved.  "K first_addr, 
-      last_address"  overrides this and allows writing ANY memory 
-      area to a file. Almost a necessity for CPM 3.0 (no SAVE!).
-      K)eep on DDTZ
-
-   X  eXamine:  redisplays the "NEXT PC SAVE" report at any time.
-  (Q) Q)uery size on DDTZ.
-
-   S  S)earch  first_address,   last_addr,  value:  searches  the 
-  (W) specified memory area for the value (a 16-bit word,  not  a 
-      byte) and shows the locations of all such.  Very useful for 
-      finding  CALL's  or JMP's to a particular address, etc.
-      W)here on DDTZ
-
-   Y  Y)our_option  parm1,parm2,address:  executes  an  arbitrary 
-      routine  at  the  specified address,   with the BC  and  DE 
-      registers  set to parm1 and parm2, respectively.
-
-   Z  Displays (but does not alter) the Z80's alternate  register 
-      set,  including the index registers (disabled if running on 
-      an  8080).  On Z80's,   automatically included  as the last 
-      part of the display by the 'X' command.
-
-
-Based (Offset) Displays:
-=======================
- 
-The  'D' and 'E' commands  can use a stored base value  (offset),  
-as  set  by   the  '@' command.   The current  @  value   may  be 
-overridden for a single execution of these commands by adding the 
-base as an extra parameter  in the command line.   The effect  is  
-to  add  this  value   to  the  first/last  address  and  display 
-accordingly.  The address listing on the left becomes  XXXX:YYYY,  
-where  XXXX  is the offset address and YYYY is the actual  memory 
-address being displayed.   For example,  if you have a data  area  
-located at  42B7H  and wish to  preserve easy access,  just enter 
-"@42b7".  Now, "d0,3f" will dump memory starting at 4237H.
-
-
-Further Changes from DDT:
-========================
-
-   A  A)ssemble  now  accepts   the  full Z80  as  well  as  8080 
-      instruction  set,  although it expects them in Intel rather 
-      than  Zilog  format  (see  notes  below   under   the   'L' 
-      command).    When in doubt, see the mnemnonic list below.
-
-   D  D)isplay or D)ump  will accept  an optional third parameter  
-      to  set the base value for a single execution only.  Format 
-      has been cleaned up.
-
-   H  H)ex_arithmetic    on   two  values   also   shows    their 
-      difference  in decimal.  With only one value,  converts  to 
-      hexadecimal, decimal, and ASCII (low-order byte only).
-
-
-   N  N)ame  now allows drive specification  (d:...)  and sets up 
-  (I) the  complete  command  line,   including  both  FCB's  (at 
-      addresses 005CH and 006CH).   The tail (stored at 0081H up) 
-      is NOT upshifted.
-      I)nput on DDTZ
-
-   U  U)nassemble now displays the raw hexcode,  especially handy 
-  (L) when examining non-code areas. Intel (8080 style) mnemonics 
-      are  used,  so  some  disassembled  instructions  may  look 
-      strange.  E.g., the Z80's 'IN B,(C)' and 'OUT (C),B' become  
-      'INP B' and 'OUTP B', respectively;  'LD (nnnn),BC' becomes 
-      'SBCD nnnn',  'ADD IX,  BC' becomes 'DADX B', and 'JP (IX)' 
-      becomes 'PCIX'. 
-      L)ist on DDTZ
-
-   L  L)oad   now  permits  loading a file into memory   with  an 
-  (R) offset,  which  is  added to the default  load  address  of 
-      0100H.   When reading in  a .HEX file  with  a preset bias,  
-      the   'R'  command will not transfer control to an  invalid 
-      execution point.  Another execution of the 'R' command will 
-      reread the input file, e.g.:
-
-         n blah<ret>
-         l<ret>
-         ...modify the code and generally mess about...
-         l<ret>
-
-      The original file  is reloaded,  and the modifications  are 
-      removed.
-      R)ead on DDTZ
-
-   E  E)nter,  like  D)isplay,  now  accepts an  optional  second 
-  (S) parameter  to  set the base value for  a  single  execution 
-      only.
-      S)ubstitute or S)et on DDTZ
-
-   T  T)rap/trace   on  termination  now shows  the complete  CPU 
-      state. Traps and traces no longer lock up  when  a user RST 
-      7 instruction is executed.   Tracing of BDOS/BIOS calls  is 
-      heavily trun cated,  avoiding clutter and preventing system 
-      crashes.
-
-NOTE: Most of the UNDOCUMENTED Z80 op-codes are handled.  Others
-      can crash the system.
-
-   R  R)egisters  also shows what two-byte values the HL  and  SP 
-  (X) registers are actually pointing to.  On Z80's, displays the 
-      alternate register set.
-      eX)amine on DDTZ
-
-NOTE: Any  use  of the 'W' or 'L' command  resets the system  DMA 
-      transfer address to the standard default value of 0080H.
