Description: 
This is a Manufacturing program on the subject of
Statistical Process Control. This program assumes 
the user have a basic knowledge of SPC. Explaining
how to interpret SPC  outputs is far beyond the
scope of my documentation.
 

features:
* The main display displays arrays&directories. user can quickly
   navigate directories or select arrays for statistical outputs. This
   was inspires by the SX statcatlog
   
*  Database for arrays
*  fast calculation & plot of control charts for Xbar & Rbar
* Unique histogram that shows normality & dispersion of a process
* Basic Statistical info for process
* Infared & Serial port print capabilites
* data management--  edit, copy, move, purge, crdir, search
*  Export feature allows Arrays to be sent to a PC. This feature
   is good if your PC SPC software have importing capabilites.

* and lots more

Analyzing outputs from this package can help detect & eliminate
execessive variation that threatens a manufacturing process. 

Enjoy!
