LOOK120
A File View Utility

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.
