\par \pard To program an arc when only the arc centre is given (the radius is unknown) use the address letters I and K.
\par I relates to the address X and is the incremental value and direction (+/-) from the start point of the arc in the X axis to the arc centre (see diagram below).
\par K relates to the address Z and is the incremental value and direction (+/-) from the start point of the arc in the Z axis to the arc centre\f1 .
