- Preface
- -------
- This program is intended for every programmer. With this utility you can
- display memory, and search something in memory.
- For example, if you have written a program and it does not work, you
- could alter your program so that it prints the address of the object you
- think is faulty. With DM you can examine this memory while your program
- is running.
-
- This program (DM V1.1) is shareware.
- If you like and/or use this utility I would appreciate it very much
- if you'd send me a contribution of $10 US ($15 if you want to get a new
- update (when one is available)).
- Please send money by international money order, EuroCheck (in Belgian
- Francs (BF) !) or cash, because it's very difficult for me to cash in
- other checks.
- If you want an update please state your current version.
- If you want to use this program for commercial purposes please write
- for permission !
-
- If you have any suggestions or remarks you can write to (Bug reports are
- welcome too)

- WARNING:
- If you want to use this utility you must have Arp 1.3 or later.
- DM is reexecutable so you can use it with ARes, Resident, ...
- DM is not reentrable, so you will get a warning from ARes or Resident
- if you try to use this program twice at the same time.
- This utility uses environment variables (DMMemoryStart, DMMemoryLines,
- DMMemoryMode and DMMemorySearch). These variables correspond more or
- less with the Start, Lines, BYTE,WORD,LONG,ASCII,SEARCH options from
- the commandline. DM uses them to continue a search or a list.

- Syntax
- ------
-
- +-----------------------------------------------------------------------+
- | Commandline template: |
- | Start,Lines,B=BYTE/s,W=WORD/s,L=LONG/s,A=ASCII/s,S=SEARCH/k: |
- |-----------------------------------------------------------------------|
- | Usage: |
- | DM [<Start> [<Lines>]] [BYTE | WORD | LONG | ASCII | SEARCH object] |
- +-----------------------------------------------------------------------+
-
- <Start> : addres to start displaying or searching
- eg
- 0xc05006 (hex address)
- #123a (hex address)
- 5000 (dec address)
- <Lines> : if you want to display memory this is the number of
- lines you want to display
- if you are searching this is the maximum number of bytes
- you want to search
- BYTE : show every long byte per byte (16 bytes per line)
- WORD : word per word ( " " " )
- LONG : long per long ( " " " )
- ASCII : show only ascii on one line (64 bytes per line)
- SEARCH object : search object
- eg
- s 'String'
- s 1253cd02a135 (hexadimal values)
-
- examples:

- DM #10000 1000 s 3200fc0512dd23a5bc
- will search this string from address hex 10000. DM will search
- for 1000 bytes.
-
- DM 0 512000 s 'DEBUG'
- will search from address 0 to the string 'DEBUG'. When the string
- is not found in 512000 bytes, the search will stop.
-
- DM
- DM without arguments repeats the last DM action.
- If for example the previous search succeeded at address 100000,
- when you execute DM again (without arguments) the program will
- continue the search the next 'DEBUG' string.
- If the previous DM action was 'DM 0 a' then executing DM without
- arguments will list the next 16 lines of memory.
-
- DM l
- If 'DM 0 10000 s 00c032a0' (search 0x00c032a0) was the previous command,
- and the object was found at 1239 then 'DM l' will list the memory (in
- longs) at this place in memory. If you want to search the next
- occurance of this long, type 'DM s 00c032a0' and the search will go
- on.
