                Patching TFM Kerning Values in WordStar for DOS
                         American Version 7.0D ONLY
                           by Rich Zuris 76702,520

The following patch allows you to change the way WordStar evaluates kerning 
information from tagged font metrics (TFM) files for the HP LaserJet series
III and 4 printers.  Normally, WordStar ignores kerning information for pairs 
that are kerned with values between 7 and -7.  If this loss of detail is 
noticeable to you, you may choose new limits.  

WARNING:  Reducing the truncation will increase the size of your custom 
database (*.DTU) and PDF.  Since this patch has not been tested by 
SoftKey Quality Assurance, unpredictable results may occur; send anomaly 
reports to SoftKey technical support along with the patched WINSTALL.EXE 
file, your DTU database, and PDF.  

RECOMMENDATION:  Change the filter value to +/- 2 (values of 02 and FE).  
This should allow all "noticeable" kerning values into the PDF while 
filtering out those that have little noticeable impact on printed documents 
but take up much PDF space.
