*Methodology*
Command:	2.2
Alpha Alias:	Divide Arc
Description:	Computes points by dividing arc segments into equal parts
Data Format:	2.2 Set Radius-Point Arc-Defined No-of-Segments ;
Problem:	Given radius point number 10 and curve point numbers 11, 12, divide the arc segment into three equal parts starting with point number 50.
Solution:	2.2 50 10 11 12 3 ;

Data Description

Command	2.2	Divides an arc segment into a specified number of equal parts and computes points at each division point.
Set	50	Point number to be assigned to the first computed coordinate. The subsequent point numbers are automatically assigned and ordered as designated by the Set point. If the Set point is entered as a positive number, the subsequent points will be numbered in increasing order. If you enter a negative number, the points that follow will be numbered in decreasing order.
Radius-Point	10	Previously computed point number that defines the radius point of the arc.
Arc-Defined	11, 12	Two point numbers defining the arc segment that were previously computed and stored, and that are located on the arc.
No-of-Segments	3	Specifies the number of equal segments into which the arc will be divided. Note: This number must be postive for points set on clockwise curves and negative for points set on counter-clockwise curves as defined by the PC and PT points. Note: The number of segments will always be one greater than the number of points set.
End Command	;	All commands end with semi-colon.
