How do you know that?

@markj, during command-line argument parsing the program refuses to operate on more datasets than MAX_DS.

[markj]

Ok, so PlotSet() sets pl->data[j * pl->width + x] |= val where 0<=val<MAX_DS. So your assertion is true, but only because MAX_DS is a power of 2.

I don't really see the value of the change to be honest.
