                 This program is released to the 
               public domain, and distribution is 
                    permitted and encouraged.

     LOOK120 is an experimental program designed to allow viewing 
of 120 columns on a standard IBM Color Display or Enhanced Color 
Display. Please forward any comments you may have to the Doctor.

     The IBM PC is designed to show text in an 80X25 matrix, 
meaning that attempts to view a file with line lengths of greater 
than 80 causes the offending lines to be cut off at 80 or (worse) 
wrapped around to the next line, making the display totally 
incomprehensible. In particular, listing (.LST) files produced by 
the Macro Assembler have long line lengths, and I quite often 
like to look at the listing file to see a memory reference or to 
check on how variables are being stored. This is very difficult 
to do with only 80 columns. LOOK120 fills this need perfectly.

     LOOK120 in its current form is functionally equivalent to 
BROWSE, a program from PC magazine. The only difference is that 
LOOK120 displays the file in a 120 columns, 27 row format. This 
means that the display is a little less readable, but if you 
adjust your monitor's intensity a bit and get lots of Vitamin A 
you should be able to make out everything.

     Invoke LOOK120 by typing:

          LOOK120 [drive:][path\]filename

     or, optionally:

          LOOK120          

     in which case the program will ask you to enter a filename.

     The first page of the file will be displayed in "compressed" 
mode. Now you can give the following single keypress commands:

     ESC       - return to DOS
     Home      - show beginning of file
     End       - show end of file
     PageUp    - show previous page of file
     PageDn    - show next page of file
     Space     - toggle "upper case" mode. Initially, the text is 
                 displayed exactly as it appears in the file. If 
                 "upper case" mode is activated all lower case 
                 letters will be made upper case, as these are a 
                 bit more readable. 

     Again, I stress that this program is its experimental stage. 
If you like the "compressed" display, please let me know and I 
will expand upon this program, giving it search functions, for 
instance. LIST120 is currently written in Turbo Pascal, but a 
finished version would certainly be in Assembler for increased 
speed.
