NO_CLEAR - Removes screen clear commands from programs

   NO_CLEAR is freeware.  It may be distributed freely but may not be
sold or included with any commercial product without the written consent
of CodeHead Software. 


   NO_CLEAR will search any program for VT-52 screen clear commands and
allow you to replace them with carriage return/line feed combinations. 
This is intended to be used with AUTO programs so that instead of each
program writing over the previous screen display, your screen will
scroll up from the bottom, which is especially useful when using
PinHead, a shareware program by Charles F. Johnson which speeds up the
running of programs (to a point where you can't even read the messages
any more).  NO_CLEAR's usefulness becomes even more apparent when you
use version 2.0 of the CodeHead RAM disk which allows you to boot your
AUTO programs off of the RAM disk at lightning speed.

After choosing a file you will be asked if you want to replace each
occurence of the screen clear command.  Note that it is not always
desirable to remove every occurence.  For this reason you should always
use a trial copy of a program rather than the original. 

   Here is a list of AUTO programs containing screen clears which I have
successfully replaced:

     Name of      Number of   Occurence
     Program      Occurences  to Replace
    -------------------------------------
     PinHead           1         1st
     Macro Utilities   1         1st
     G+Plus            1         1st
     LGSelect          1         1st
     STSelect          1         1st
     UIS               1         1st
     CodeHead Spooler  1         1st
     HotWire           3         3rd only


   I'm sure there are many more programs that could benefit from removal
of screen clear commands.  Happy scrolling. 


Technical Description
---------------------

   NO_CLEAR is searching for the VT-52 command "Clear-Home", that is,
Escape "E" (27,69), which clears the screen and places the cursor at the
upper left corner of the screen.  These are replaced (if you confirm) by
CR/LF (carriage return/line feed), or (13,10) which will instead move
the cursor to the left margin and one line down (scrolling the screen up
if on the bottom line).
