The values range from 0-15, indicating that the corresponding colour palette entry is the left range of the animation channel's range. 4 words - Right animation limit table Same as the one for left, but this value should be greater than or equal to the corresponding left animation limit value for proper operation. 4 words - Animation channel direction flag This is a table of 4 word values which specify the cycling direction for the corresponding animation channel. A value of 0 indicates that the channel shifts its colours to the left,1= channel is off, and 2=a right shift. 4 words - Animation channel delay This is a 4 word value table which specifies the speed at which the colour registers in the animation channel range will be shifted. The range of permissible values in these variables are 0- 128, indicating the number of 60Hz delay periods between colour shifts. A value of zero in this table indicates the max speed, approx. 60 shifts per second; a value of 60 is approx. one shift per second; a value of 120 is roughly one shift every two seconds. Well that is the file format for Degas and Degas Elite pics. As I said the bottom 16 words are optional. later Barry P.S. Could someone that has the RTX multi-tasking prg., please send me a short review of it.
