The so-called spread sheet is a traditional managerial tool which aids in the
analysis of financial information.   Data is presented in rows and columns
and may represent sales information, inventory, etc.  As a company's budget
changes, the data in the rows and columns are changed accordingly, and the
entire array can be re-examined.  ColorCalc is a computerized spread sheet
which automatically totals the information you are after.  The results can be
handed over to another program, ColorGraph, which will then provide color
graphic displays.  Both programs are written in assembly language.

ColorCalc has 12 single-key commands, such as "L" to load data files or
"D" for data entry.  As many as 51 columns and 52 rows of data may be
entered.  A formula may be entered on the basis of which the data will
then automatically be analyzed.  Such a formula may operate on any
column or row any number of times.  And up to ten formulas may be saved.
(24 formulas on 3600 machines).  ColorCalc operates with a triple-precision
math package which is accurate to the penny up to five billion dollars.
Hard copy print out is supported.

ColorGraph takes data from ColorCalc and draws graphs of any section of the
spread sheet.  You can rescale the graphs, re-color them, relabel them,
and print them --- in black and white on an Epson, for example, or in color
using the PrintaColor inkjet printer.
