This is the default display mode for files that were loaded  in Auto Mode as text data

This selection is disabled for non-Text files, or if Hex Mode Lock is selected.

Settings
Setting WnScroll options

Telling WnScroll how to load a file for display.

Use the options in the File types box set the mode for a file read.

These options become effective on the next file to be loaded.

Auto detect   (default)

will load a file in Text form if possible, otherwise will display a file as formatted Hex data.

Hex (binary)

forces load and display of a file as formatted Hex data,  regardless of file type.

Text

treats the file as Text data, regardless of actual file type.  Useful for over-ride when

the Auto mode fails to recognise a text file.  (see Notes )

Warning ON

if this check-box is enabled, WnScroll will display a warning message if you attempt to

load a binary file while Text mode is locked on. (press OK to continue or Cancel to stop.)

Telling WnScroll how to display a file that is already loaded

Use the buttons in the Display box to choose the display type.

HEX button,	TEXT button (default)

these buttons duplicate the same functions in the Display menu

ASCII Filter  check-box  (default ON in Text Mode)

causes TABS to be expanded, and filters out non-printable characters.

Set File Types list box

click on arrow button to select from Text Files or Hex Files in the drop-down list box.

The File Extensions edit box displays the file extensions you want treated as either

Text or Hex. You may add, delete or modify the contents of this data to suit your own

preferences. Seperate each file extension by a comma.

Click the OK button to register your changes, or the Cancel button to ignore them.


Notes:

WnScroll treats all files as either raw binary (HEX) or as printable characters (TEXT).

When set to Auto detect, WnScroll will attempt to display files in the most suitable format.

If a text file is recognised, WnScroll will display it as plain text. ( you may manually  switch to

HEX and back to TEXT at will))

In some cases WnScroll fails to correctly identify a text file, usually because of embedded format

characters contained in some types of document files. You can over-ride the Auto detect and force WnScroll to load a file in text mode by checking the Text  button in the File types box

A word of caution:    you can force WnScroll to read any file in Text Mode, including files that are

non-text in content,but in some cases an attempt to display such files in Text format will cause

unpredictable results within WnScroll.      Don't force text mode lock unless you need to.

Since all files are actually Hex data, any file type can be processed and displayed in Hex mode.

You may lock Hex mode if you want to force WnScroll to treat all files as binary only. However, any files loaded this way cannot be displayed in Text format (unless first reloaded in Auto or Text mode).
