                            GENERAL INFORMATION

This program simply computes degree and hour angle equivalents for a
given angular argument expressed in decimal or sexagesimal format.


The angular input argument can be entered as a string of one to three
numerical elements.

For example, a single input '1.25' would be interpreted as 1.25 degrees
or hours of arc or time.

The dual input '5 35' would be interpreted as 5 or degrees or hours and
35 minutes of arc or time.

The triple input '17 02 03.456' would be interpreted as 17 degrees or
hours and 3 minutes and 3.456 seconds of arc or time.

Anything following the third element is ignored.

The program also displays the angle in radians and its basic circular
trigonometric functions, the sine, cosine and tangent.
