- | Program Invocation |
- | |
- +--------------------------------------------------------------------------+
-
- Within the following discussion, none of the parameters is case-sensitive.
- Lower case is used to indicate values that are supplied by you; upper case
- is used to signify values that must be coded as shown.
-
- All switches are shown preceded by a "/"; the switch character may be coded
- as "-" for those of you who prefer this character.
-
- The program is invoked as follows:
-
- DUMP filename [range] [/dest] [/hi-bit] [/width] [/base] [/quit] [/K:blks]
-
- where:
-
- "DUMP" is coded as shown
-
- "filename" is a required parameter, and must be the first parameter
- specified. A drive and/or path may be supplied.
-
- "range" is optional; if omitted, the entire file will be dumped.
- If specified, then any of the following formats may be used:
-
- (a) start [default "stop" value = end of file]
- (b) start stop
- (c) Lnnn [default "start" value = 0]
- (d) start Lnnn
- (e) Lnnn start
- (f) [omitted] [defaults to entire file]
-
- "4G-1" below indicates 4,294,967,295 (hex FFFFFFFF)
-
- "start" is the starting offset within the file (range 0 to 4G-1)
- (default 0)
- "stop" is the ending offset within the file (range "start" to 4G-1)
- (default is last byte in file, unless "Lnnn" is coded)
- "L" is coded as shown, to indicate 'length'
- "nnn" is the number of bytes to be dumped (range 1 to 4G-1)
- (default is remaining file length, unless "stop" is coded)
-
- For format (b), the "stop" value must not be less than the
- start value.
-
- For formats (d) and (e), the sum of "start"+"nnn" must not
- exceed 4G-1.
-
- Radix: For "start", "stop", and "nnn", the value may be coded with a
- prefix indicating one of the following bases:
-
- $ (Hexadecimal): $hhhhhhhh (max. FFFFFFFF)
- ^ (Decimal ): ^nnnnnnnnnn (max. 4294967295 [4G-1])
- % (Octal ): %kkkkkkkkkkk (max. 37777777777)
- # (Binary ): #b...b (max. 1...1 [32 digits])
-
- If the prefix is omitted, the default base is hexadecimal,
- unless otherwise overridden by the "/radix" switch (see
- below).
-
- In all cases, the print range will be converted to offset
- values, and shown on the listing in hexadecimal.
-
- "/dest" is optional; if omitted, the default is "/D"
-
- This controls the destination of the output, and may be coded:
-
- /D (screen via DOS calls; no color coding)
- /S (screen via BIOS calls, with color coding)
- /M (screen via BIOS calls, monochrome)
- /P (printer direct, via DOS calls)
-
- If your video adapter card does not support color mode, then /S
- should be avoided (unpredictable results will occur).
-
- If you use DOS re-direction to the printer (rather than the /P
- switch), then you should also avoid /S.
-
- Refer to the "/width" and "/K:blks" switches below for output
- sizes.
-
- Refer to "Color and Character Translation" for color values
- in use for screen output.
-
- "/hi-bit" is optional; if omitted, the default is "/7"
-
- This controls the high-order bit processing for the character
- portion of the dump for output via DOS calls. Allowable values
- are:
-
- /7 (strip the high-order bit)
- /8 (leave the high-order bit as is)
-
- If /S or /M is in effect, /8 will be assumed unconditionally
- (/7 will be accepted without any indication of error).
-
- Refer to "Color and Character Translation" for character
- translation in the character portion of the output.
-
- "/width" is optional; if omitted, the default is "/N"
-
- This controls the page width. Allowable values are:
-
- /N (narrow) - print 16 bytes of data per line
- /W (wide) - print 32 bytes of data per line
-
- For output to the screen, a check will be made to ensure that
- the current screen width is sufficient to permit /W to be in
- effect. If /W output is directed to the printer, it is your
- responsibility to ensure that the printer has been set up to
- accept print lines of 132 characters.
-
- "/base" is optional; if omitted, the default is "/$"
-
- This controls the radix for "start, "stop" and "nnn" (length)
- values, unless such values are explicitly coded with a radix
- indicator. Allowable values are:
-
- /$ (hexadecimal)
- /^ (decimal)
- /% (octal)
- /# (binary)
-
- "/quit" is optional; if omitted, the default is "/C"
-
- This controls the processing of the (Esc) key during program
- execution. Allowable values are:
-
- /C (confirmation of Esc key required)
- /Q (quit immediately after Esc key is pressed)
-
- "/K:blks" is optional; if omitted, the default is "/K:1" for screen
- output, and "/K:3" for printer output.
-
- This controls the page length. The "blks" value must be coded
- as a one-digit decimal number (range 1 to 9), and defines the
- number of blocks of data lines per page, where a block consists
- of 16 print lines, corresponding to 100H bytes in /N mode, and
- 200H bytes of data in /W mode.
-
- Note that the "/radix" switch has no effect on the
- interpretation of the number specified for "blks".
-
- Once the "page" is complete, a new set of header information
- will be printed (a formfeed will be sent to the printer if /P
- is in effect).
-
- If output is directed to the printer, it is your responsibility
- to ensure that the printer has been set up to accept a minimum
- of ((16*blks) + 12) lines per page.
-
- Page size: The default "page" size for output to the screen is 16 lines,
- plus header information; the default "page" size for output to
- the printer is 48 lines, plus page header information (with a
- form-feed sent at the end of every page).

- +--------------------------------------------------------------------------+
-
- Parameter Parsing Tolerances
- ----------------------------
-
- The "filename" must be present, and must be the first parameter. However,
- the remaining optional parameters may be coded in any order (with the single
- exception noted below), separated by at least one blank (optionally any
- number of additional blanks will be accepted).
-
- The "/" indicating switch values need not be preceded by a blank.
-
- If the "range" values are codes as 'start stop', then the "stop" value must
- follow the "start" value, although any switch values may occur between the
- two values.
-
- The following are acceptable forms:
-
- DUMP FILE.EXT /P $00F0/8 ^300 range 240 (hex F0) to 300
- DUMP FILE.EXT L%40 #111 range 7 (bin 111) to 38 (7+32-1)
-
- Parameter errors
- ----------------
-
- Duplicate or conflicting parameters will cause an error to be reported. For
- example, /D and /S may not appear together; the presence of 3 numeric values
- in the "range" specification is illegal, and so on.
-
- The "start" value may not exceed the file length.
-
- The "stop" value (whether coded explicitly or resulting from "Lnnn") must
- not be less than the "start" value and not greater than the file length.

- | Program Execution Control |
- | |
- +--------------------------------------------------------------------------+
-
- While the program is executing the following keys will be recognized:
-
- 1-9 and 0 (scroll delay rate for screen output)
- -----------------------------------------------
-
- The "1" key will cause a long delay at the end of each line
- (slow scrolling)
- The "9" key will cause a short delay at the end of each line
- (fast scrolling)
- Keys "2" to "8" cause the delay to be progressively decreased
- (i.e. the scroll rate will progressively increase)
- The "0" key will cause a zero delay at the end of each line
- ('express' scrolling)
-
- The program starts at speed "0" ('express')
-
- (spacebar) or "P" key to pause the listing
- ------------------------------------------
-
- After a pause has been requested, any key other than (Esc) will cause the
- dump program to resume. The (Esc) key will cause the immediate
- termination of the program (regardless of the /C or /Q setting).
-
- (Esc) to request termination
- ----------------------------
-
- After termination has been requested, you will be prompted to confirm the
- request by pressing the (Esc) key a second time if /C is in effect; any
- other key will cause the program to resume. If /Q is in effect, the
- program will terminate immediately.
-
- Recognition of keystrokes
- -------------------------
-
- Requests for termination or pause will be detected immediately, but will
- not be processed until the end of the current output line.
-
- Similarly, changes in the scroll rate will be detected immediately, but
- will not cause a change in the scroll rate until the end of the current
- output line.

-
- Color Values
- ------------
-
- For /D, the default DOS color settings will be used.
-
- For /S and /M, the following colors will be used:
-
- character range (hex) Color for /S Color for /M
- ======================= ============= =============
- 00-1F red white
- 20-7F (printable ASCII) bright yellow white
- 80-9F magenta white
- A0-FF bright green white
-
- Character Translation
- ---------------------
-
- For /S and /M, no character translation will occur (all bytes will be
- displayed as is).
-
- For /D and /P, the following character translation will occur:
-
- character range (hex) /8 /7
- ======================= ========== ===========
- 00-1F . (period) . (period)
- 20-7E (printable ASCII) as is as is
- 7F . (period) . (period)
- 80-9F . (period) . (period)
- A0-FE as is 20-7E
- FF . (period) . (period)
