[ASCII] (Hex)

Operand Format Comments
Extended ASCII (Contour <ws><ICS-count>[<ws><IP-counti>]\
+<ws><Ixl>,<Iyl>[<ws><Ixj>,<Iyj>]+)
Absolute coordinates.
Single-byte, binary operand [k] (6B) <BCS-count>[<USCS-Ecount>][<BP-counti>[USP-Ecounti>]]\
+<Lx1><Ly1>[<Lxj><Lyj>]+
Relative coordinates, 32 bit.
- [Ctrl-k](0B) <BCS-count>[<USCS-Ecount>][<BP-counti>[USP-Ecounti>]]\
+<Sx1><Sy1>[<Sxj><Syj>]+
Relative coordinates, 16-bit.
P-counti   The number of points in the ith contour. Must be 2 or greater. In the binary operand form, a value of zero for P-count indicates that an extended count (P-Ecount) will follow

P-Ecount   When P-count is zero, a 2-byte extended count follows allowing for values from 256 through 65,791 which are encoded as an integer (0 to 65,535).

X1,Y1   The first point (in logical coordinates) in the first contour.

Xj,Yj   The jth point (in logical coordinates) in the nth contour.
