Formatted File Data Dump in Hexadecimal and ASCII

Syntax

os9dump [<opts>] [<path>] [<addr>]

Function

os9dump produces a formatted display of the physical data contents

<path>, which may be a mass storage file or any other I/O device.

The

os9dump utility is commonly used to examine the contents of

non-text files.

To use this utility, type

os9dump, the pathlist, and the address within the

file if desired, of the file to display. If you omit

<path>, standard input is

used. The output is written to standard output. When you specify

<addr>, the contents of the file display, starting with the appropriate

address.

os9dump assumes that <addr> is a hexadecimal number.

The data is displayed 16 bytes per line in both hexadecimal and ASCII

character format. Data bytes that have non-displayable values are

represented by periods in the character area.

The addresses displayed on the

os9dump are relative to the beginning of

the file. Because memory modules are position-independent and stored in

files exactly as they exist in memory, the addresses shown on the dump are

relative to the load addresses of the memory modules.
