Numeric circular block words [TURN]

Reserved word	Definition
<ARC-X>	Used in the circular interpolation block to specify the signed X distance from the start point of the arc, to the center of the arc along the X axis.
<ARC-Z>	Used in the circular interpolation block to specify the signed Z distance from the start point of the arc, to the center of the arc along the Z axis.
<RADIUS>	Returns the arc radius in a circular block.
<S-RAD>	Generates the signed arc radius value in a circular block, +R<180 degrees and R>180 degrees.
<Z-CEN>	Returns the absolute Z coordinate position from the Z axis origin to the arc's center in a circular block.
<X-CEN>	Returns the absolute X coordinate position from the X axis origin to the arc's center in a circular block.

Note: To generate the signed distance from the arc's center to the arc's start position, locate the <ARC-Z> and <ARC-X> reserved words in the Word Formatting dialog, and change their FACTOR values to -1. To generate the unsigned distance from the arc's start position to the center of an arc, select the Unsigned value options for these reserved words in the Words Info dialog.
