Current position

GDDM V3R2 Base Application Programming Reference
SC33-0868-02

The GDF order formats given below contain all relevant coordinates. However, for brevity the start position of the graphics primitive can be omitted. When omitted, current position is used in its place.

Current position is set by each of the orders. It is set to the end point of a line or arc and, except for character strings, the rule is the same as for the corresponding GDDM function.

The difference between an order that specifies the first coordinate pair, and an order that assumes the current position as the starting position is shown by the state of bit 1 of the order code, thus:

0: The order specifies the first coordinate pair.
1: The order assumes the current position as the starting position.
