Show Hex is a 100% assembly program that lets you view and search data in
a file or system memory. For ease of use, input is supported through both
the keyboard and the mouse. In addition, simple integration into the
DC Desktop environment is implemented.
* Getting started
To use from the GEM desktop:
Execute the program. An alert will query you to Run|Install|Quit.
Choosing Install without DC Desktop will Run the program. Once the
file selector appears, choose the file you wish to view.
Another option for DC Desktop 1.2 owners:
Place in the auto folder to auto install in the SHOW chain.
* Screen Display
Data is represented in a three column format: offset, hex value, and
ascii value.
1) Offset is the hex displacement in either the file or memory.
2) Hex value is the byte equivalent of the data. ( FF Hex = 256 Decimal )
3) Ascii value is the text equivalent of the data byte. ( 9 Ascii = 39 Hex )
* DC Desktop Owners
DC Show 1.2 scans the file to show and determines its contents- ascii
or binary data.
While viewing a text file you can toggle to Show Hex with [H].
A binary file is handed off to Show Hex with no toggling accepted.
Control+F2 calls it up when installed.
NOTE: Show Hex is fully supported only in version 1.2 of DC Desktop
with DC Show. There are no restrictions with the use of DC Pick
and/or DC Menu.
