*Methodology*
Command:	77
Alpha Alias:	List CLSta
Description:	Prints increasing centerline stations to three decimal places
Data Format:	77,LineID Station From {Radius-Pt} To {[{Radius-Pt} To] .. } ;
Problem:	Given a series of centerline points and radius points defining an alignment with a starting station of 15+73.24 . Compute and print centerline stationing as shown.
Solution:	77,1 1573.24 99 101 100.1 102 97 111 110.1 112 98 ;

Data Description

Command	77	Prints centerline stations to 3 decimal places in sequence, starting at the specified station point. Prints bearings, distances, and curve data.
LineID	1	Integer value to be used as the object number for the centerline.
Station	1573.24	Station value of the starting point of the centerline.
From	99	Point number of the starting point of the centerline. If you are defining a curve, enter the Point of Curvature (PC) point number.
{Radius-Pt}		Optional radius point if you are defining a curve. Append .1 to this point number to indicate it as the radius point. Enter this value as a negative number if the curve has a delta angle greater than 180° as in a cul-de-sac.
To	101	Point number of the next point to be stationed on the centerline. If you are defining a curve, enter the number of the Point of Tangency (PT).
[{Radius-Pt} To] .. }	100.1 102 97 111 110.1 112 98	Repeating feature of this command. Enter successive points to be stationed. If you are defining a curve, you must enter the radius point with .1 appended to the number, then enter the PT point number. The point entered immediately before the radius point is considered the PC of the curve.
End Command	;	All commands end with a semi-colon.

$     ADVANCED example of using subcommands
$     to calculate distances from known points. 
$     The advantage is that you can change the 
$     width of the road in the 11 command and 
$     it will recalc here to match.
