CUSTOM VIEWER Ver. 1.0 is released into Public Domain and may be distributed 
freely provided this text file (C_Viewer.txt) accompanies it.

The block saving feature should be handled carefully.  There is no error 
trapping.  Check a saved block for accuracy before deleting the  origonal 
test file.

The  program is dimensioned to allow 20,000 lines of text.   This is  303 
pages of 66 lines.

I realize that one thing the ST world doesn't really need is  another 
text viewer.  What started as a small program to allow wider line spacing 
to more easily read the online magazines eventually, evolved into this 
program.  (the evolution process resulted in a larger than necessary 
program, future revisions will attempt to reduce it's size). The 
underlying goal of the program was to allow the flexibility to change its 
various parameters with relative ease, as circumstances and tastes 
dictated.  Such a feature is block saving which was added to allow pieces 
of a text file to be clipped for future reference without exiting and 
loading up a text editor.


PROGRAM FEATURES

MAIN MENU (BOTTOM OF THE SCREEN)

o FONT SELECTION 

The font selection menu allows the selection of the;

     Normal System font - single spaced
     Normal System font - double spaced

                    a graphics mode
     Small Font   - Graphics font at 106 characters per line
     Large Font   - Double height graphics font

The graphics fonts write to the screen more slowly than the system fonts 
but allow for fractional line spacing which the normal system fonts 
don't.

The font selection menu presets the line spacing
