- ABOUT THIS PROGRAM
- ---------------------------------------------------------------------------
-
- Name : ShowFile
- Version : 1.01 (13 Feb 1995)
- Purpose : *Type/List/Dump files
- Author : Andrew Berry
- Licence : Freeware. Please see conditions at the end of this file.
-
-
- PURPOSE
- ---------------------------------------------------------------------------
- This program is designed to display files of any type using the * commands
- Type, List and Dump. Why can't this be done from the command line? Well, it
- can, only this way is easier. It has the following advantages over the
- command line:
-
- - A specified mode can be entered, the file displayed, and
- then the original desktop mode re-entered. This means that even if
- you normally use mode 27 for the desktop you can set the program to
- display files in a wide screen mode, eg 39, then return to mode 27.
-
- - Options are selected from a window.
-
- - Files are selected by dragging instead of typing long filenames.
-
-
- USING THE PROGRAM
- ---------------------------------------------------------------------------
- Three types of display can be selected. These are Type, List and Dump, and
- are described in detail later.
-
- The main window is opened by clicking on the ShowFile icon on the icon bar.
- It contains four options. These are:
-
- Mode : This selects the mode which will be entered before
- displaying the file. If the mode specified is unsuitable
- then an alternative will be suggested, or a reason given as
- to why it is unsuitable.
-
- Tab expand : This can only be used with the Type and List options, and
- becomes unselectable if Dump is chosen. It has the effect
- of replacing ASCII 9 characters with 8 spaces when
- selected.
-
- Offset : When selected, this specifies the offset from the beginning
- of the file from which to dump the data. Can only be used
- with Dump.
-
- Start : This can only be used if the 'Offset' option is ticked and
- is otherwise greyed out. When selected, it displays the
- file as if it were in memory starting at the specified
- address.
-
- Both the offset and start addresses must be entered in hexadecimal.
-
- Files are displayed by dragging from the filer window onto either the
- ShowFile icon on the icon bar or the options window. Use Ctrl, Shift and
- Scroll Lock as normal to look through the file slowly.
-
- All options take effect as soon as they are altered and are not (currently)
- saved to disc.
-
-
- TYPES OF DISPLAY [RISC OS 3 PRM's page reference]
- ---------------------------------------------------------------------------
- Type : This displays the file using the configured DumpFormat. [2-190]
- List : As Type, but each line is numbered. [2-171]
- Dump : Displays the file in hexadecimal and ASCII codes. [2-162]

- HISTORY
- ---------------------------------------------------------------------------
- 1.00 (21 Jan 1995) - • The first version, fully working. Type, list, dump,
- specify mode, tabexpand, offset and start addresses.
- ---------------------------------------------------------------------------
- 1.01 (13 Feb 1995) - • Bug fix. Pressing Escape when a file was being
- displayed brought up an empty error box on return
- to the desktop.
-
-
- THINGS TO DO
- ---------------------------------------------------------------------------
- • Include option for *Print. This is more complicated as all characters are
- sent to the VDU and some can cause 'unwanted screen effects' and need to
- be filtered out.
- • Option for paged scrolling (a serious omission at the moment)
- • Save options to disc
