Draw_Pat_VL ($F437)

These routine draws a series of patterned vectors. The pattern to use must already be specified in $C829. The number of vectors to draw minus 1 must be specified in $C823. The vector list, pointed to by the X register, has the following format:

rel y, rel x, rel y, rel x, ...

Draw_Pat_VL_d starts at the (y,x) coordinates specified in the D register and ignores the first pair of coordinates in the vector list.



DP = $D0

X-reg points to the vector list

$C829 contains the line pattern.



X-reg points to next byte after list

D-reg trashed
