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.
