("Priority Build") Tell PHost which build orders you want to have executed first. X is a digit between 1 and 9. You can use each of these 9 friendly codes to designate up to 9 priority builds, PB1 being the most important (first). This friendly code is enabled with the AllowPriorityBuild config option. The exact interpretation depends on the build queue mode (BuildQueue).
- Fifo and PAL queue: the PB build orders are moved to the head of the build queue when you set these friendly codes. You can then reset the friendly codes.
- PBP queue: when you are granted a priority build, PHost performs your most important build order (PBx, with smallest x). Hence you have to keep these friendly codes all the time, because you don't usually know when you'll be granted a priority build.
Full details are on the Build Queue page.
